Smith, B. A. & Nayar, S. K., Mining Controller Inputs to Understand Gameplay. Proc. ACM UIST, Tokyo, Japan, 2016, 157 – 168.

Today’s game analytics systems are powered by event logs, which reveal information about what players are doing but offer little insight about the types of gameplay that games foster. Moreover, the concept of gameplay itself is difficult to define and quantify. In this paper, we show that analyzing players’ controller inputs using probabilistic topic models allows game developers to describe the types of gameplay — or action — in games in a quantitative way. More specifically, developers can discover the types of action that a game fosters and the extent that each game level fosters each type of action, all in an unsupervised manner. They can use this information to verify that their levels feature the appropriate style of gameplay and to recommend levels with gameplay that is similar to levels that players like. We begin with latent Dirichlet allocation (LDA), the simplest topic model, then develop the player-gameplay action (PGA) model to make the same types of discoveries about gameplay in a way that is independent of each player’s play style. We train a player recognition system on the PGA model’s output to verify that its discoveries about gameplay are in fact independent of each player’s play style. The system recognizes players with over 90% accuracy in about 20 seconds of playtime.

Miau, D. & Feiner, S., Personalized Compass: A Compact Visualization for Direction and Location. Proc. ACM CHI, Santa Clara, CA, USA, May 7-12, 2016, 5114 – 5125.

Maps on mobile/wearable devices often make it difficult to determine the location of a point of interest (POI). For example, a POI may exist outside the map or on a background with no meaningful cues. To address this issue, we present Personalized Compass, a self-contained compact graphical location indicator. Personalized Compass uses personal a priori POIs to establish a reference frame, within which a POI in question can then be localized. Graphically, a personalized compass combines a multi-needle compass with an abstract overview map. We analyze the characteristics of Personalized Compass and the existing Wedge technique, and report on a user study comparing them. Personalized Compass performs better for four inference tasks, while Wedge is better for a locating task. Based on our analysis and study results, we suggest the two techniques are complementary and offer design recommendations.

Game engines have become popular development platforms for real-time interactive systems. Contemporary game engines, such as Unity and Unreal, feature component-based architectures, in which an object’s appearance and behavior is determined by a collection of component scripts added to that object. This design pattern allows common functionality to be contained within component scripts and shared among different types of objects. In this paper, we describe a flexible framework that enables programmers to design modular, reusable widgets for real-time interactive systems using a collection of component scripts.

We provide a reference implementation written in C# for the Unity game engine. Making an object, or a group of objects, part of our managed widget framework can be accomplished with just a few drag-and-drop operations in the Unity Editor. While our framework provides hooks and default implementations for common widget behavior (e.g., initialization, refresh, and toggling visibility), programmers can also define custom behavior for a particular widget or combine simple widgets into a hierarchy and build arbitrarily rich ones. Finally, we provide an overview of an accompanying library of scripts that support functionality for testing and networking.

In many complex tasks, a remote subject-matter expert may need to assist a local user to guide actions on objects in the local user’s environment. However, effective spatial referencing and action demonstration in a remote physical environment can be challenging. We introduce two approaches that use Virtual Reality (VR) or Augmented Reality (AR) for the remote expert, and AR for the local user, each wearing a stereo head-worn display. Both approaches allow the expert to create and manipulate virtual replicas of physical objects in the local environment to refer to parts of those physical objects and to indicate actions on them. This can be especially useful for parts that are occluded or difficult to access. In one approach, the expert points in 3D to portions of virtual replicas to annotate them. In another approach, the expert demonstrates actions in 3D by manipulating virtual replicas, supported by constraints and annotations. We performed a user study of a 6DOF alignment task, a key operation in many physical task domains, comparing both approaches to an approach in which the expert uses a 2D tablet-based drawing system similar to ones developed for prior work on remote assistance. The study showed the 3D demonstration approach to be faster than the others. In addition, the 3D pointing approach was faster than the 2D tablet in the case of a highly trained expert.

Assembly or repair tasks often require objects to be held in specific orientations to view or fit together. Research has addressed the use of AR to assist in these tasks, delivered as registered overlaid graphics on stereoscopic head-worn displays. In contrast, we are interested in using monoscopic head-worn displays, such as Google Glass. To accommodate their small monoscopic field of view, off center from the user’s line of sight, we are exploring alternatives to registered overlays. We describe four interactive rotation guidance visualizations for tracked objects intended for these displays.

Many tasks in real or virtual environments require users to view a target object or location from one of a set of strategic viewpoints to see it in context, avoid occlusions, or view it at an appropriate angle or distance. We introduce ParaFrustum, a geometric construct that represents this set of strategic viewpoints and viewing directions. ParaFrustum is inspired by the look-from and look-at points of a computer graphics camera specification, which precisely delineate a location for the camera and a direction in which it looks. We generalize this approach by defining a ParaFrustum in terms of a look-from volume and a look-at volume, which establish constraints on a range of acceptable locations for the user’s eyes and a range of acceptable angles in which the user’s head can be oriented. Providing tolerance in the allowable viewing positions and directions avoids burdening the user with the need to assume a tightly constrained 6DoF pose when it is not required by the task. We describe two visualization techniques for virtual or augmented reality that guide a user to assume one of the poses defined by a ParaFrustum, and present the results of a user study measuring the performance of these techniques. The study shows that the constraints of a tightly constrained ParaFrustum (e.g., approximating a conventional camera frustum) require significantly more time to satisfy than those of a loosely constrained one. The study also reveals interesting differences in participant trajectories in response to the two techniques.

We present a 3D referencing technique tailored for remote maintenance tasks in augmented reality. The goal is to improve the accuracy and efficiency with which a remote expert can point out a real physical object at a local site to a technician at that site. In a typical referencing task, the remote expert instructs the local technician to navigate to a location from which a target object can be viewed, and then to attend to that object. The expert and technician both wear head-tracked, stereo, see-through, head-worn displays, and the expert’s hands are tracked by a set of depth cameras. The remote expert first selects one of a set of prerecorded viewpoints of the local site, and a representation of that viewpoint is presented to the technician to help them navigate to the correct position and orientation. The expert then uses hand gestures to indicate the target.

Smith, B. A., Yin, Q., Feiner, S. K., & Nayar, S. K., Gaze locking: Passive eye contact detection for human-object interaction, Proc. ACM UIST, 2013, 271 – 280.
Eye contact plays a crucial role in our everyday social interactions.  The ability of a device to reliably detect when a person is looking at it can lead to powerful human–object interfaces. Today, most gaze-based interactive systems rely on gaze tracking technology. Unfortunately, current gaze tracking techniques require active infrared illumination, calibration, or are sensitive to distance and pose.  In this work, we propose a different solution — a passive, appearance-based approach for sensing eye contact in an image.  By focusing on gaze locking rather than gaze tracking, we exploit the special appearance of direct eye gaze, achieving a Matthews correlation coefficient (MCC) of over 0.83 at long distances (up to 18 m) and large pose variations (up to ±30° of head yaw rotation) using a very basic classifier and without calibration.  To train our detector, we also created a large publicly available gaze data set: 5,880 images of 56 people over varying gaze directions and head poses.  We demonstrate how our method facilitates human–object interaction, user analytics, image filtering, and gaze-triggered photography.

Magic-lens style augmented reality applications allow users to control camera pose easily by manipulating a portable hand-held device and provide immediate visual feedback. However, strategic vantage points must often be revisited repeatedly, adding time and error and taxing memory. We describe a new approach that allows users to take snapshots of augmented scenes that can be virtually revisited at later times. The system stores still images of scenes along with camera poses, so that augmentations remain dynamic and interactive. Users can manipulate virtual objects while viewing snapshots, instead of moving to real-world views. We present a study comparing performance in snapshot and live mode conditions in a task in which a virtual object must be aligned with two pairs of physical objects. Proper alignment requires sequentially visiting two viewpoints. Participants completed the alignment task significantly faster and more accurately using snapshots than when using the live mode. Moreover, participants preferred manipulating virtual objects using snapshots to the live mode.

We describe a set of interaction techniques that allow a user of a magic-lens style augmented reality application to take snapshots of an augmented scene and revisit them virtually for interaction at a later time. By storing a still image of the background along with the camera pose, this approach allows augmentations to remain dynamic and interactive. This makes it possible for the user to manipulate virtual objects from the vantage points of different locations without the overhead of physically traveling between those locations. Preliminary results from a user study show that participants were able to complete an alignment task significantly faster and as accurately when using snapshots as opposed to physical travel. Qualitative questionnaire answers showed that participants preferred using snapshots over walking and found it less demanding.

As patients are encouraged to become active participants in their own care, recent research has begun to explore the direct sharing of electronic health information with patients during hospital visits. The design of patient-facing views of clinical information is, however, a relatively recent line of inquiry. Research is needed to further understand guidelines for communicating specific types of information to hospital patients. In this work, we focus on cardiology patients’ information needs related to their hospital medications. We assessed these needs to inform the design of interactive, electronic views of medication information for cardiology inpatients. We present results of in-situ interviews with 11 inpatients and 6 nurses in a cardiology step-down unit. Our findings suggest that cohesive trends in medication information needs exist across cardiology inpatients. We discuss interview results and their implications for the design of inpatient-facing information technology. We also discuss key ways in which electronic medication information, formatted for inpatient use, differs from that formatted for outpatient or transitional medication-management use.

Procedural tasks are common to many domains, ranging from maintenance and repair, to medicine, to the arts. We describe and evaluate a prototype augmented reality (AR) user interface designed to assist users in the relatively under-explored psychomotor phase of procedural tasks. In this phase, the user begins physical manipulations, and thus alters aspects of the underlying task environment. Our prototype tracks the user and multiple components in a typical maintenance assembly task, and provides dynamic, prescriptive, overlaid instructions on a see-through head-worn display in response to the user’s ongoing activity. A user study shows participants were able to complete psychomotor aspects of the assembly task significantly faster and with significantly greater accuracy than when using 3D-graphics–based assistance presented on a stationary LCD. Qualitative questionnaire results indicate that participants overwhelmingly preferred the AR condition, and ranked it as more intuitive than the LCD condition.

We describe a simple modeling application and an urban visualization tool in which the information presented on the head-worn display supplements the information displayed on the tabletop, using a variety of approaches to track the head-worn display relative to the tabletop. In all cases, our goal is to allow users who can see only the tabletop to interact effectively with users wearing head-worn displays.

Building on our institution’s commercial electronic health record and custom personal health record Web portal, we developed a tablet computer application to provide interactive information to hospital patients. Using Apple iPad devices, the prototype application was provided to five patients in a cardiology step-down unit. We conducted detailed interviews to assess patients’ knowledge of their inpatient care, as well as their perceptions of the usefulness of the application. While patients exhibited varying levels of comfort with using the tablet computer, they were highly enthusiastic about the application’s ability to supply health information such as their inpatient medication histories and photographs of their care providers. Additional research is warranted to assess the benefit such applications may have for addressing inpatient information needs, enhancing patient-provider communication and improving patient satisfaction.

Objective: To support collaboration and clinician-targeted decision support, electronic health records (EHRs) must contain accurate information about patients’ care providers. The objective of this study was to evaluate two approaches for care provider identification employed within a commercial EHR at a large academic medical center.

Methods: We performed a retrospective review of EHR data for 121 patients in two cardiology wards during a four-week period. System audit logs of chart accesses were analyzed to identify the clinicians who were likely participating in the patients’ hospital care. The audit log data were compared with two functions in the EHR for documenting care team membership: 1) a vendor-supplied module called “Care Providers”, and 2) a custom “Designate Provider” order that was created primarily to improve accuracy of the attending physician of record documentation. Results: For patients with a 3–5 day hospital stay, an average of 30.8 clinicians accessed the electronic chart, including 10.2 nurses, 1.4 attending physicians, 2.3 residents, and 5.4 physician assistants. The Care Providers module identified 2.7 clinicians/patient (1.8 attending physicians and 0.9 nurses). The Designate Provider order identified 2.1 clinicians/patient (1.1 attending physicians, 0.2 resident physicians, and 0.8 physician assistants). Information about other members of patients’ care teams (social workers, dietitians, pharmacists, etc.) was absent.

Conclusions: The two methods for specifying care team information failed to identify numerous individuals involved in patients’ care, suggesting that commercial EHRs may not provide adequate tools for care team designation. Improvements to EHR tools could foster greater collaboration among care teams and reduce communication-related risks to patient safety.

We present results of a survey study indicating that it may be possible to automatically generate such explanations by extracting individual sentences from consumer-facing Web pages. We further inform future work by characterizing physician and non-physician responses to a variety of Web-extracted explanations of medical lab tests.

Hospital information systems have primarily been designed to support physicians and administrators, though recent research has explored the value of patient-facing information displays. Electronic systems can be designed to provide tailored information to patients on their health, their care teams, the status of their hospital stays, and their expected care plans. However, this direct delivery of information from database to patient represents a fundamental change to the traditional flow of clinical information. We therefore explore physician attitudes toward a proposed patient-facing display of information abstracted from a hospital EHR, in the context of an urban emergency department. We find that physicians generally support direct delivery of electronic information to patients, and uncover important concerns to consider in the design of patient-facing information systems.

We describe fieldwork in which we studied hospital ICU physicians and their strategies and documentation aids for

ActiveNotes integrates automated, context-sensitive patient data retrieval, and user control of automated data updates and alerts via tagging, into the documentation process. We performed a qualitative study of activeNotes with 15 physicians at the hospital to explore the utility of our information retrieval and tagging techniques. The physicians indicated their desire to use tags for a number of purposes, some of them extensions to what we intended, and others new to us and unexplored in other systems of which we are aware. We discuss the physicians’ responses to our prototype and distill several of their proposed uses of tags: to assist in note content management, communication with other clinicians, and care delivery.

Electronic medical records are increasingly comprehensive, and this vast repository of information has already contributed to medical efficiency and hospital procedure. However, this information is not typically accessible to patients, who are frequently under-informed and unclear about their own hospital courses. In this paper, we propose a design for in-room, patient-centric information displays, based on iterative design with physicians. We use this as the basis for a Wizard-of-Oz study in an emergency department, to assess patient and provider responses to in-room information displays. 18 patients were presented with real-time information displays based on their medical records. Semi-structured interviews with patients, family members, and hospital staff reveal that subjective response to in-room displays was overwhelmingly positive, and through these interviews we elicited guidelines regarding specific information types, privacy, use cases, and information presentation techniques. We describe these findings, and we discuss the feasibility of a fully-automatic implementation of our design.

St-Aubin B., Mostafavi M., Roche S., Dedual N., A 3D Collaborative Geospatial Augmented Reality System for Urban Design and Planning Purposes, Canadian Geomatics Conference 2010, Apr 2010.
In typical urban planning and design scenarios, good collaboration between implicated participants is fundamental but not necessarily easy to achieve. This can be due to a variety of factors ranging from the different backgrounds of the people involved to the complexity of the tools used by the experts. Furthermore, the collaborative aspect of urban planning and design is often limited to the meetings where designs and plans are assembled and discussed. This paper presents a system we designed to resolve those problems through a collaborative geospatial augmented reality application acting as an intuitive multi-user interactive scale model aiming to facilitate decision-making in urban planning and design projects. The proposed system integrates innovative technologies of geospatial augmented reality with tools for 3D modelling and spatial analysis in order to establish a collaborative augmented reality based urban planning and design system. Early results from our experimentations demonstrate the interesting potential of such a system for interactive and collaborative urban planning and design. The paper presents a comparison of the proposed approach with the existing ones and proposes further development as future work.

This paper explores how historical models of documents as stable information artifacts should be replaced with a new model of information objects that exist around and between document boundaries. The new model is information-centered; files and documents are seen as snapshots in time, part of individual and group information flows. The flows are versioned across multiple documents and applications. This model is based on new fine-grained tracking and analysis capabilities derived from machine learning research. Using these capabilities, we outline a view of documents based on results from an experiment that tracked the activities of 17 information workers doing their regular work over 8 weeks. The research supports certain postmodern theories of work, specifically the notion of “pasting up.” The construct of provenance describes information flows and networks and is the core theoretical base of the paper. The research had two goals: to understand what users do moment to moment and to provide insight for information management. There are further implications for information design in managing multi-tasking workloads, for methods of studying computer-based work, and for an updated desktop user interface

We present activeNotes, a prototype application that supports the creation of Critical Care Notes by physicians in a hospital intensive care unit. activeNotes integrates automated, context-sensitive patient data retrieval and user control of automated data updates and alerts into the note-creation process. In a user study at New York Presbyterian Hospital, we gathered qualitative feedback on the prototype from 15 physicians. The physicians found activeNotes to be valuable and said they would use it to create both formal notes for medical records and informal notes. One surprising finding is that while physicians have rejected template-based clinical documentation systems in the past, they expressed a desire to use activeNotes to create personalized, physician-specific note templates to be reused with a given patient, or for a given condition.

Many collaborative applications, especially in scientific research, focus only on the sharing of tools or the sharing of data. We seek to introduce an approach to scientific collaboration that is based on the sharing of knowledge. We do this by automatically building organizational memory and enabling knowledge sharing by observing what users do with a particular tool or set of tools in the domain, through the addition of activity and usage monitoring facilities to standalone applications. Once this knowledge has been gathered, we apply social networking models to provide collaborative features to users, such as suggestions on tools to use, and automatically-generated sequences of actions based on past usage amongst the members of a social network or the entire community. In this work, we investigate social networking models as an approach to scientific knowledge sharing, and present an implementation called genSpace, which is built as an extension to the geWorkbench
platform for computational biologists. Last, we discuss the approach from the viewpoint of social software engineering.
