Greenberg, Saul and Fels, Sidney (2009): Exploring video streams using slit-tear visualizations. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3509-3510. Available online

“Slit-tear visualizations allow users to selectively visualize pixel paths in a video scene. The slit-tear visualization technique is a generalization of the traditional photographic slit-scanning and more recent video slicing techniques: after a user specifies a pixel path of interest, the system generates a timeline that replicates those pixels for each frame in the video. These rich visualizations of the video data help users to discover and explore spatio-temporal patterns of activity in a video. In this video, we illustrate the use of slit-tear visualizations to detect movement and incidence of activity in a video scene, accentuate directional motion and small changes in the video, and discover patterns of activity between spatially distinct areas of the scene.”

“In this paper, we explore the practice of using a whiteboard for multiple tasks, and specifically how users employ whiteboards to smoothly transition between related sets of tasks. Our study underscores several basic, but important affordances of whiteboards that support this practice, including visual persistence, flexibility of interaction primitives, and their situated physicality. We discuss the implications of these findings for the design of large display applications.”

You, Wei, Fels, Sidney and Lea, Rodger (2008): Studying vision-based multiple-user interaction with in-home large displays. In: Proceedings of the 2008 ACM International Workshop on Human-Centered Multimedia 2008. pp. 19-26. Available online

“Large displays at home such as TVs are becoming larger in size and more interactive in functionality. When multiple co-located users share the screen space of a large display, when, where and how to display their media contents becomes an issue. This paper compares the use of automatic versus manual methods for managing personal screen real-estate on large in-home displays. We assume horizontally laid out "personal interaction spaces" as the user interface for multiple users to manage their screen real-estate. In this case, users need to sign in and out as well as have their personal spaces placed on the display. We constructed a computer-vision based system that tracks the identities and positions of multiple people in front of the display to support the user studies that compare the use of tracker-based mechanisms versus manual ones for managing the display. Our results suggest that the tracking system shows promise for a) simplifying the user registration process in conjunction with a manual sign-in/out process and b) effective tracker-based user-centric placement of people's interaction space. Proper integration of manual methods could improve the sense of control and ownership for users.”

“We report preliminary results of our ongoing field study of IT professionals who are involved in security management. We interviewed a dozen practitioners from five organizations to understand their workplace and tools. We analyzed the interviews using a variation of Grounded Theory and predesigned themes. Our results suggest that the job of IT security management is distributed across multiple employees, often affiliated with different organizational units or groups within a unit and responsible for different aspects of it. The workplace of our participants can be characterized by their responsibilities, goals, tasks, and skills. Three skills stand out as significant in the IT security management workplace: inferential analysis, pattern recognition, and bricolage.”

In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 501-510. Available online

“Cooking is a daily activity for many people. However, traditional text recipes are often prohibitively difficult to follow for people with language disorders, such as aphasia. We have developed a multi-modal application that leverages the retained ability of aphasic individuals to recognize image-based representations of objects, providing a presentation format that can be more easily followed than a traditional text recipe. Through a systematic approach to developing a visual language for cooking, and the subsequent case study evaluation of a prototype developed according to this language, we show that a combination of visual instructions and navigational structure can help individuals with relatively large language deficits to cook more independently.”

Proceedings of ACM CHI 2004 Conference on Human Factors in Computing Systems April 24-29, 2004, Vienna, Austria. pp. 327-334. Available online

“In this paper we consider the general goal of supporting physical manipulation of digital audio in a specific context: the performance disk jockey (DJ) seeking to migrate from vinyl to digital media. We classify both the DJ's traditional processes and tools and the field's newest technology. D'Groove, our own technological contribution, is a force feedback turntable used to manipulate digital audio in novel ways. We present an observational study of professional DJ's using D'Groove, and discuss this approach's attributes and directions for future augmentation. Finally, we extend our conclusions about the DJ's emerging needs to the broader domain of digital audio manipulation.”

“We have created a gradient-based face navigation interface that allows users to explore a large face space based on an eigenface technique. This approach to synthesizing faces contrasts with more typical techniques for forming composite faces based on the blending of facial features. We compare three ways of moving through the face space, using two types of sliders and a face-wheel. These are adapted from typical color space interfaces since they are commonly used. However, eigenface dimensions do not have meaningful text labels, unlike primary colors, necessitating the use of faces themselves for the labels of the navigation axes. Results suggest that users can navigate with face-labelled axes. They find slider interfaces best suited to finding the neighborhood of a target face, but that the face-wheel is better for refinement once inside the neighborhood.”

Proceedings of the ACM CHI 2000 Human Factors in Computing Systems Conference April 1-6, 2000, The Hague, The Netherlands. pp. 540-547. Available online

“This paper demonstrates how non-isomorphic rotational mappings and interaction techniques can be designed and used to build effective spatial 3D user interfaces. In this paper, we develop a mathematical framework allowing us to design non-isomorphic 3D rotational mappings and techniques, investigate their usability properties, and evaluate their user performance characteristics. The results suggest that non-isomorphic rotational mappings can be an effective tool in building high-quality manipulation dialogs in 3D interfaces, allowing our subjects to accomplish experimental tasks 13% faster without a statistically detectable loss in accuracy. The current paper will help interface designers to use non-isomorphic rotational mappings effectively.”

Fels, Sidney and Hinton, Geoffrey (1995): GloveTalkII: An Adaptive Gesture-to-Formant Interface. In: Katz, Irvin R., Mack, Robert L., Marks, Linn, Rosson, Mary Beth and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 95 Human Factors in Computing Systems Conference May 7-11, 1995, Denver, Colorado. pp. 456-463. Available online

“Glove-TalkII is a system which translates hand gestures to speech through an adaptive interface. Hand gestures are mapped continuously to 10 control parameters of a parallel formant speech synthesizer. The mapping allows the hand to act as an artificial vocal tract that produces speech in real time. This gives an unlimited vocabulary, multiple languages in addition to direct control of fundamental frequency and volume. Currently, the best version of Glove-TalkII uses several input devices (including a Cyberglove, a ContactGlove, a polhemus sensor, and a foot-pedal), a parallel formant speech synthesizer and 3 neural networks. The gesture-to-speech task is divided into vowel and consonant production by using a gating network to weight the outputs of a vowel and a consonant neural network. The gating network and the consonant network are trained with examples from the user. The vowel network implements a fixed, user-defined relationship between hand-position and vowel sound and does not require any training examples from the user. Volume, fundamental frequency and stop consonants are produced with a fixed mapping from the input devices. One subject has trained for about 100 hours to speak intelligibly with Glove-TalkII. He passed through eight distinct stages while learning to speak. He speaks slowly with speech quality similar to a text-to-speech synthesizer but with far more natural-sounding pitch variations.”

INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 683-688.

“A multilayer neural network can learn complicated mappings from inputs to outputs. After learning a mapping from a set of training examples, the network can generalize to new cases. Although the learning can be slow, the network runs extremely rapidly once it has learned so it can be used for real-time applications. To illustrate the potential of this technology for adaptive interfaces, we used a VPL DataGlove connected to a DECtalk speech synthesizer via five neural networks to implement a hand gesture to speech system. Using minor variations of the standard back-propagation learning procedure, the complex mapping of hand movements to speech is learned using data obtained from a single "speaker" in a simple training phase. With a 203 gesture-to-word vocabulary, the wrong word is produced less than 1% of the time, and no word is produced about 7% of the time. Adaptive control of the speaking rate and word stress is also available. The training times and final performance speed are improved by using small, separate networks for each naturally defined subtask. The system demonstrates that neural networks can be used to develop the complex mappings required in a high bandwidth interface that adapts to the individual user.”
