“…To improve the use of screen space, Tula et al [16] proposed that contexts can be dynamically resized. Thus, the context that receives the user focus is maximized, while the other context is minimized.…”

“…We conducted an user experiment to compare the performance of dynamic context switching and dwell time, and to evaluate the combinaton of dwell time with meta-keys. To analyze the data, we adapted the metrics defined in [16] and [17], as described in the next Section.…”

“…The objective of Experiment 1, as described in [16], [17], is to compare the performance of dynamic contexts with fixedsize contexts in a multiple selection task, common in real world applications, such as navigating a collection of pictures or multimedia objects. Another objective is to evaluate the use of meta-keys for navigation and command activation, in a task that required browsing through several pages of items.…”

“…Speed can be compared using the time needed to complete the task, that is computed from the selection of the "Begin" key to the selection of the "Exit" key. In the experiment of Tula et al [16], since each trial could have a different number of digits, it is not fair to use the absolute total time task to compare performance between the different layouts. Therefore, the authors averaged the total time task by the number of selections, including digits and non-digits.…”

“…To improve the context switching paradigm, two extensions have been proposed: the use of contexts with dynamic sizes [16] and the use of meta-keys as escape mechanism to extend the functionality of the interfaces [17]. The purpose of dynamic context switching is to increment the useful screen space by dynamically adjusting the size of the contexts.…”

In this paper we investigate the performance of a gaze-based interaction system that combines Dynamic Context Switching and Meta-Context Switching. These methods are extensions of the Context Switching interaction paradigm. The original context switching idea uses fixed-size contexts. Each context carries the same information, so the user can browse freely within a context without worrying about the Midas touch problem. A saccade to the other context triggers the selection of the item under focus. Dynamic context switching dynamically adjusts the size of a context to improve its useful area, where the context that has the user focus is displayed in full size and the other is minimized. Meta-context switching uses meta-keys to allow the user to escape from the current task and select other contexts or change the operation mode. We have designed and conducted two user experiments to evaluate these new gaze interaction techniques and compare them with selection by dwell time in a search task. The task required browsing through several pages using meta-keys. The experimental results show that dynamic context switching improves user performance when compared to fixed-size context switching and do not cause disorientation. The error rate was significantly higher for dwell time due to the Midas touch problem, although the time spent to complete the task was similar for dwell time and dynamic context switching.

In this paper, we propose a calibration-free gaze-based text entry system that uses smooth pursuit eye movements. We report on our implementation, which improves over prior work on smooth pursuit text entry by 1) eliminating the need of calibration using motion correlation, 2) increasing input rate from 3.34 to 3.41 words per minute, 3) featuring text suggestions that were trained on 10,000 lexicon sentences recommended in the literature. We report on a user study (N=26) which shows that users are able to eye type at 3.41 words per minutes without calibration and without user training. Qualitative feedback also indicates that users positively perceive the system. Our work is of particular benefit for disabled users and for situations when voice and tactile input are not feasible (e.g., in noisy environments or when the hands are occupied).
