“…However, the choice of the output modality also depends on the context in which such devices are used and worn. For instance, in some contexts of use, interaction with mobile and wearable devices needs to be subtle (Pohl, Muresan, and Hornbaek, 2019), non-disturbing to the user and the others (Anderson, Grossman, Wigdor, and Fitzmaurice, 2015), while nevertheless retaining highly informative and effective qualities despite temporary situations and interaction-related constraints determined by the context of use (Heller, Vanacken, Geurts, and Luyten, 2020;Wobbrock, 2019).…”

We introduce VIREO, a web-based software tool for graphical authoring of vibrotactile feedback for mobile and wearable applications. VIREO enables flexible specification of vibrotactile patterns with model-based and free-draw sketch input, and is compatible with mobile and wearable devices that support JavaScript, either natively at the platform level or in a web browser. We demonstrate the practical utility of VIREO by presenting several applications implemented for a smartphone, smartwatch, smart armband, and a pair of smartglasses that integrate vibrotactile feedback patterns authored with VIREO. Also, we present the results of an usability evaluation study involving sixteen participants represented by coders with various programming experience and levels of programming language proficiency, including JavaScript. We discuss our contribution in the context of the results of a Systematic Literature Review that we conducted on the topic of software tools, editors, and platforms developed in the scientific community for authoring vibrotactile feedback. Since one major finding of our review is the little availability of such contributions, we release VIREO as a free web resource for researchers and practitioners that wish to author and integrate vibrotactile feedback in mobile and wearable applications.

“…This type of impairment affects the interaction between user and interface. However, synchronizing interfaces with user needs is a beneficial approach in these situations (Biswas, Langdon, Umadikar, Kittusami, & Prashant, 2014;Heller, Vanacken, Geurts, & Luyten, 2020). Gaze interaction can be utilized to minimize users' close interaction with machines and equipment in high-risk environments or cases of any motor disability (Karlsson, Allsop, Dee-Price, & Wallen, 2018).…”

Significant advancements of eye-tracking technology in extended reality (XR) head-mounted displays have increased the interest in gaze-based interactions. The benefits of gaze interaction proved that it could be a suitable alternative for hand-based interactions when users face situations where they must maintain their position due to mobility impairment. This study aims to assess the user experience of the gaze-based interaction, compared to hand-based interaction, in two movement conditions of static and dynamic. Twenty-four participants took part in this study, and their experience was evaluated in terms of perceived workload, usability, and performance. The results show that gaze-based interactions significantly outperform the hand-based interaction in terms of perceived workload and usability in case of limited mobility. Also, the user performance is significantly higher in gaze-based modes under situational impairment. The findings of this study can be used for designing XR interfaces considering the situation in which the task is performed.
