Improving User Interfaces for Robot Teleoperation

The FXPAL robotics research group has recently explored technologies for improving the usability of mobile telepresence robots. We evaluated a prototype head-tracked stereoscopic (HTS) teleoperation interface for a remote collaboration task. The results of this study indicate that using a HTS systems reduces task errors and improves the perceived collaboration success and viewing experience. We […] → Read More: Improving User Interfaces for Robot Teleoperation

video text retouch

Several of us just returned from ACM UIST 2014 where we presented some new work as part of the cemint project.  One vision of the cemint project is to build applications for multimedia content manipulation and reuse that are as powerful as their analogues for text content.  We are working towards this goal by exploiting two key tools.  First, we […] → Read More: video text retouch

Ego-Centric vs. Exo-Centric Tracking and Interaction in Smart Spaces

In the recent paper published at SUI 2014,”Exploring Gestural Interaction in Smart Spaces using Head-Mounted Devices with Ego-Centric Sensing”, co-authored with Barry Kollee and Tony Dunnigan, we studied a prototype Head Mounted Device (HMD) that allows the interaction with external displays by input through spatial gestures. In the paper, one of our goals was to […] → Read More: Ego-Centric vs. Exo-Centric Tracking and Interaction in Smart Spaces

Gesture Viewport: Interacting with Media Content Using Finger Gestures on Any Surface

At ICME 2014 in Chengdu, China, we presented a technical demo called “Gesture Viewport,” which is a projector-camera system that enables finger gesture interactions with media content on any surface. In the demo, we used a portable Pico projector to project a viewport widget (along with its content) onto a desktop and a Logitech webcam […] → Read More: Gesture Viewport: Interacting with Media Content Using Finger Gestures on Any Surface

SearchPanel: supporting exploratory search in regular search engines

People often use more than one query when searching for information. We revisit search results to re-find information and build an understanding of our search need through iterative explorations of query formulation. Unfortunately, these tasks are not well supported by search interfaces and web browsers. The only indication of our search process we get is […] → Read More: SearchPanel: supporting exploratory search in regular search engines

AirAuth: Authentication through In-Air Gestures Instead of Passwords

At the CHI 2014 conference, we demonstrated a new prototype authentication system, AirAuth, that explores the use of in-air gestures for authentication purposes as an alternative to password-based entry. Previous work has shown that passwords or PINs as an authentication mechanism have usability issues that ultimately lead to a compromise in security. For instance, as […] → Read More: AirAuth: Authentication through In-Air Gestures Instead of Passwords

Improving the Expressiveness of Touch Input

Touch input is now the preferred input method on mobile devices such as smartphones or tablets. Touch is also gaining traction in the desktop segment and is also common for interaction with large table or wall-based displays. At present, the majority of touch displays can detect solely the touch location of a user input. Some […] → Read More: Improving the Expressiveness of Touch Input

Looking ahead

It is reasonably well-known that people who examine search results often don’t go past the first few hits, perhaps stopping at the “fold” or at the end of the first page. It’s a habit we’ve acquired due to high-quality results to precision-oriented information needs. Google has trained us well. But this habit may not always […] → Read More: Looking ahead

In Defense of the Skeuomorph, or Maybe Not…

Jony Ive is a fantastic designer. As a rule, his vision for a device sets the trend for that entire class of devices. Apparently, Jony Ive hates skeuomorphic design elements. Skeuomorphs are those sometimes corny bits of realism some designers add to user interfaces. These design elements reference an application’s analog embodiment. Apple’s desktop and mobile interfaces […] → Read More: In Defense of the Skeuomorph, or Maybe Not…
