Expressive haptics for enhanced usability of mobile interfaces in situations of impairments
Designing for situational awareness could lead to better solutions for
disabled people, likewise, exploring the needs of disabled people could lead to
innovations that can address situational impairments. This in turn can create
non-stigmatising assistive technology for disabled people from which eventually
everyone could benefit. In this paper, we investigate the potential for
advanced haptics to compliment the graphical user interface of mobile devices,
thereby enhancing user experiences of all people in some situations (e.g.
sunlight interfering with interaction) and visually impaired people. We explore
technical solutions to this problem space and demonstrate our justification for
a focus on the creation of kinaesthetic force feedback. We propose initial
design concepts and studies, with a view to co-create delightful and expressive
haptic interactions with potential users motivated by scenarios of situational
and permanent impairments.Comment: Presented at the CHI'19 Workshop: Addressing the Challenges of

Situational impairments to mobile interaction in cold environments
Abstract
We evaluate the situational impairments caused by cold ambient temperature on fine-motor movement and vigilance during mobile interaction. For this purpose, we tested two mobile phone applications that measure fine motor skills and vigilance in controlled temperature settings. Our results show that cold adversely affected participants’ fine-motor skills performance, but not vigilance. Based on our results we highlight the importance of correcting measurements when investigating performance of cognitive tasks to take into account the physical element of the tasks. Finally, we identify a number of design recommendations from literature that can mitigate the adverse effect of cold ambiance on interaction with mobile devices
