Porta Ce Cursor A Contextual Eye Cursor For General Pointing In Windows Envir...Kalle
Eye gaze interaction for disabled people is often dealt with by designing ad-hoc interfaces, in which the big size of their elements compensates for both the inaccuracy of eye trackers and the instability of the human eye. Unless solutions for reliable eye cursor control are employed, gaze pointing in ordinary graphical operating environments is a very difficult task. In this paper we present an eye-driven cursor for MS Windows which behaves differently according to the “context”. When the user’s gaze is perceived within the desktop or a folder, the cursor can be discretely shifted from one icon to another. Within an application window or where there are no icons, on the contrary, the cursor can be continuously and precisely moved. Shifts in the four directions (up, down, left, right) occur through dedicated buttons. To increase user awareness of the currently pointed spot on the screen while continuously moving the cursor, a replica of the spot is provided within the active direction button, resulting in improved pointing performance.

Blignaut Visual Span And Other Parameters For The Generation Of HeatmapsKalle
Although heat maps are commonly provided by eye-tracking and visualization tools, they have some disadvantages and caution must be taken when using them to draw conclusions on eye tracking results. It is motivated here that visual span is an essential component of visualizations of eye-tracking data and an algorithm is proposed to allow the analyst to set the visual span as a parameter prior to generation of a heat map.
Although the ideas are not novel, the algorithm also indicates how transparency of the heat map can be achieved and how the color gradient can be generated to represent the probability for an object to be observed within the defined visual span. The optional addition of contour lines provides a way to visualize separate intervals in the continuous color map.

Morimoto Context Switching For Fast Key Selection In Text Entry ApplicationsKalle
This paper presents context switching as an alternative to selection by dwell time. The technique trades screen space for comfort and speed. By replicating the interface on two separate regions called contexts, the user can comfortably explore the whole content of a context without the effects of the Midas touch problem. Focus within a context is set by a short dwell time and fast selection is done by switching contexts. We present experimental results for a text entry application with 7 participants that show significant speed
improvement over traditional fixed dwell time gaze controlled keyboards. After 8 sessions, 6 participants were able to type about 12 words per minute (wpm), and the fastest participant was able to type
above 20 wpm with error rate under 2%.
