This paper describes the Liveboard, a large interactive display system. With nearly one million pixels and an accurate, multi-state, cordless pen, Liveboard provides basis for research on user interfaces group meetings, presentations remote collaboration. We describe underlying hardware software of along with several applications that have been developed. In describing system, we point out design rationale was used to make various choices. present results informal survey users, some...

Live streaming platforms bring events from all around the world to people's computing devices. We conducted a mixed methods study including interviews (N = 42) and survey 223) understand how people currently experience using Facebook Live, Periscope, Snapchat Stories. identified four dimensions that make remote event viewing engaging: immersion, immediacy, interaction, sociality. find both live streams more curated content found on are immersive immediate, yet Stories enable quickly...

We conducted a mixed methods study of the use Meerkat and Periscope apps for live streaming video audio broadcasts from mobile device. crowdsourced task to describe content, setting, other characteristics 767 streams. also interviewed 20 frequent streamers explore their motivations experiences. Together, data provide snapshot early practices. found diverse range activities broadcast, which interviewees said were used build personal brand. They described as providing an authentic, unedited...

We explored the use of awareness information to facilitate communication by developing a series prototypes. The ConNexus prototype integrates information, instant messaging, and other channels in an interface that runs on desktop computer. Awarenex extends functionality wireless handheld devices, such as Palm. A speech also enables callers make over telephone. While prototypes offer similar functionality, interfaces reflect different design affordances context each platform. discuss...

The Montage prototype provides lightweight audio-video glances among distributed collaborators and integrates other applications for coordinating future contact. We studied a group across three conditions: before installing Montage, with after removing Montage. collected quantitative measures of usage as well video-tape user perception data. found that the used short, interactions were like face-to-face conversations in many respects. Yet phone, offered convenient access to people without...

We examined records of minute-by-minute computer activity coupled with information about the location activity, online calendar appointments, and e-mail activity. present a number visualizations data that exhibit meaningful patterns in users' activities. demonstrate how vary between individuals within according to time day, location, day week. Some augment schedule found people's calendars. discuss applications for group coordination (especially across zones) plus opportunities future...

This paper describes VideoDraw, a shared drawing tool, and the process by which it is being designed developed. VideoDraw prototype, videobased, tool that provides "virtual sketchbook" among two or more collaborators. It not only allows collaborators to see each others' drawings, but also conveys accompanying hand gestures of creating using those drawings. Its design stems from studying how people collaborate spaces. Design implications raised studies were embodied in was turn observed use...

Finding 10 balloons across the U.S. illustrates how Internet has changed way we solve highly distributed problems.

Even with the investment of significant resources, video communication in professional settings has not gained mass appeal. This contrasts consumer space where, despite limited resources and low quality solutions, services such as Skype have seen widespread adoption. In this paper, we explore behavior attitudes individuals who actively use both their personal lives. We highlight similarities differences across these two domains, particular focus on interpersonal relationships, spaces,...

This paper describes a new Augmented Reality (AR) system called HoloLens developed by Microsoft, and the interaction model for supporting collaboration in this space with other users. Whereas traditional AR is between two or more head-mounted displays (HMD) users, we describe single HMD user others who join hitching on view of user. The remote companions participate remotely through Skype-enabled devices such as tablets PC's. novel use 3D digital objects where parties can be achieved...

As a field, telepresence has grown to include wide range of systems, from multi-view videoconferencing units humanlike androids. However, the diversity systems and research makes it difficult form holistic understanding where field stands. We propose framework consisting seven design dimensions for telepresence, iteratively developed previous literature, series three surveys, construction two probes, study. These uniquely categorize 17 scenarios. In this work, we explain our development...

Working from home has become a mainstream work practice in many organizations during the COVID-19 pandemic. While remote received much scholarly and public attention over years, we still know little about how people with disabilities engage their homes what access means this context. To understand rethink accessibility work, present paper studies work-from-home practices of neurodivergent professionals who have Autism Spectrum Disorder, Attention Deficit Hyperactivity learning (e.g.,...

To understand the lived experience of how people with disabilities telework in United States, 25 were interviewed. The participants included who are blind or low vision, deaf hard hearing, neurodiverse, have limited mobility/dexterity, and chronic health issues. interviews focused on they used video calling, screen sharing, collaborative editing technologies to accomplish their telework. found ways which design choices made interact people's abilities, especially those since tools rely...

Virtual reality (VR) has the potential to transform many aspects of our daily lives, including work, entertainment, communication, and education. However, there been little research into understanding usability VR for people with mobility limitations. In this paper, we present results an exploration understand accessibility limited mobility. We conducted semi-structured interviews 16 about their thoughts on, experiences with, systems. identified 7 barriers related physical devices that might...

Workplaces around the globe are beginning to rapidly adopt hybrid meetings conduct, plan, and organize their work. While previous literature explores benefits drawbacks of meetings, experiences professionals with disabilities largely missing. With an orientation towards accessible future work, we interviewed 21 unpack accessibility barriers, opportunities, conflicts meetings. We highlight creative ways developed workarounds repairs these tensions. Our paper expands understanding in by...

Much of the support for communication across distributed communities has focused on meetings and intentional contact. However, most interactions within co-located groups occur when people happen to run into each other. Such unintended should also be supported among communities. We conducted a study patterns large, organization found that tend disseminate information using formal techniques, even though usually receive informally. then designed system called Piazza is intended range styles...

Small group design sessions were empirically studied to understand better collaborative workspace activity. A conventional view of activity may be characterized as concerned only with storing information and conveying ideas through text graphics. Empirical evidence shows that this is deficient in not accounting for how the used: a) a setting, rather than by an individual, b) part process constructing artifacts, just medium resulting artifacts themselves. An understanding needs include role...
