Agustin, Javier San, Hansen, John Paulin, Hansen, Dan Witzner and Skovsgaard, Henrik (2009): Low-cost gaze pointing and EMG clicking. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3247-3252. Available online

“Some severely disabled people are excluded from using gaze interaction because gaze trackers are usually expensive (above $10.000). In this paper we present a low-cost gaze pointer, which we have tested in combination with a desktop monitor and a wearable display. It is not as accurate as commercial gaze trackers, and walking while pointing with gaze on a wearable display turned out to be particularly difficult. However, in front of a desktop monitor it is precise enough to support communication. Supplemented with a commercial EMG switch it offers a complete hands-free, gaze-and-click control for less than $200.”

“We investigate if the gaze (point of regard) can control a remote vehicle driving on a racing track. Five different input devices (on-screen buttons, mouse-pointing low-cost webcam eye tracker and two commercial eye tracking systems) provide heading and speed control on the scene view transmitted from the moving robot. Gaze control was found to be similar to mouse control. This suggests that robots and wheelchairs may be controlled "hands-free" through gaze. Low precision gaze tracking and image transmission delays had noticeable effect on performance.”

“Eye movements are the only means of communication for some severely disabled people. However, the high prices of commercial eye tracking systems limit the access to this technology. In this pilot study we compare the performance of a low-cost, webcam-based gaze tracker that we have developed with two commercial trackers in two different tasks: target acquisition and eye typing. From analyses on throughput, words per minute and error rates we conclude that a low-cost solution can be as efficient as expensive commercial systems.”

“This paper introduces and explains the concept of single stroke gaze gestures. Some preliminary results are presented which indicate the potential efficiency of this interaction method and we show how the method could be implemented for the benefit of disabled users and generally how it could be integrated with gaze dwell to create a new dimension in gaze controlled interfaces.”

“Facial EMG for selection is fast, easy and, combined with gaze pointing, it can provide completely hands-free interaction. In this pilot study, 5 participants performed a simple point-and-select task using mouse or gaze for pointing and a mouse button or a facial-EMG switch for selection. Gaze pointing was faster than mouse pointing, while maintaining a similar error rate. EMG and mouse-button selection had a comparable performance. From analyses of completion time, throughput and error rates, we concluded that the combination of gaze and facial EMG holds potential for outperforming the mouse.”

“The experiment described in this paper, shows a test environment constructed with two information spaces; one large with 2000 nodes ordered in semi-structured groups in which participants performed search and browse tasks; the other was smaller and designed for precision zooming, where subjects performed target selection simulation tasks. For both tasks, modes of gaze- and mouse-controlled navigation were compared. The results of the browse and search tasks showed that the performances of the most efficient mouse and gaze implementations were indistinguishable. However, in the target selection simulation tasks the most efficient gaze control proved to be about 16% faster than the most efficient mouse-control. The results indicate that gaze-controlled pan/zoom navigation is a viable alternative to mouse control in inspection and target exploration of large, multi-scale environments. However, supplementing mouse control with gaze navigation also holds interesting potential for interface and interaction design.”

“The aim of this paper is to examine the learning processes that subjects undertake when they start using gaze as computer input. A 7-day experiment with eight Japanese students was carried out to record novice users' eye movement data during typing of 110 sentences. The experiment revealed that inefficient eye movements was dramatically reduced after only 15-25 sentences of typing, equal to approximately 3-4 h of practice. The performance data fits a general learning model based on the power law of practice. The learning model can be used to estimate further improvements in gaze typing performance. Our experimental results encourage the use of gaze-based interfaces for severely disabled people. This paper provides a taxonomy for gaze actions on dwell time-activated keys and it presents a method by which the learnability of gaze interfaces may be documented.”

Johansen, Anders Sewerin and Hansen, John Paulin (2006): Augmentative and alternative communication: the future of text on the move. In Universal Access in the Information Society, 5 (2) pp. 125-149

“The methods currently available for text entry on small mobile devices exhibit poor performance in terms of input speed, which presents a potential barrier to acceptance and growth. This paper presents an analysis of mobile text entry indicating that the likely solution is a combination of the use of language modelling and careful interaction design and verification. The paper argues that research in augmentative and alternative communication (AAC) is highly relevant to the mobile text entry problem and vice versa, and offers the opportunity to research solutions that will be feasible to implement on future generations of mobile devices. In the design of the system presented in this paper, fewer input buttons, natural language processing (NLP) and multimodal inputs are techniques that have been evaluated and applied. Contrary to initial expectations, analysis and evaluation showed that usability and human factors often are more significant factors in performance than the efficiency of the input method. In the conducted study, simplifications of a text-to-talk system”

“The current methods available for text entry on small mobile devices suffer from poor performance which presents a potential barrier to acceptance and growth. Our analysis of mobile text entry indicates that the likely solution lies in aggressive use of language technology which is beyond the capabilities of current mobile devices. We argue that research in augmentative and alternative communication is highly relevant to the mobile text entry problem and offers the opportunity to research solutions that will be possible on future generations of mobile devices. Fewer input buttons, Natural Language Prosessing (NLP) and multimodal inputs are techniques applied in our design.”

Proceedings of the ACM CHI 96 Human Factors in Computing Systems Conference April 14-18, 1996, Vancouver, Canada. pp. 496-503.

“This is an overview of the recent progress leading towards a full subject-centered paradigm in human-computer interaction. At this new phase in the evolution of computer technologies it will be possible to take into account no just characteristics of average human beings, but create systems sensitive to the actual states of attention and intentions of interacting persons. We discuss some of these methods concentrating on the use of eye-tracking and brain imaging. The development is based on the use of eye movement data for a control of output devices, for gaze-contingent image processing and for disambiguating verbal as well as nonverbal information.”
