The document summarizes a study on elderly users' text entry performance on touchscreens. It found that elderly users had higher error rates when using mobile devices compared to tablets. The most common errors were omissions, where users forgot to type words. Insertion errors were also common on mobile devices and correlated with hand tremor. Substitution errors were more common on mobile devices and often due to poor aiming accuracy. Based on the findings, the document suggests implications for touchscreen keyboard design like shifting layouts, understanding typing behaviors, addressing poor aiming, allowing personalization, and compensating for hand tremor. It concludes more research is needed to analyze tremor data and develop touch models.
HoliBraille: Multipoint Vibrotactile Feedback on Mobile DevicesHugo Nicolau
Presentation at Web for All Conference 2015 (W4A'15) #w4a15
We propose HoliBraille, a system that enables Braille input and output on current mobile devices. We use vibrotactile motors combined with dampening materials in order to actuate directly on users’ fingers. The prototype can be attached to current capacitive touchscreen devices enabling multipoint and localized feedback. HoliBraille can be leveraged in several applications including educational tools for learning Braille, as a communication device for deaf-blind people, and as a tactile feedback system for multitouch Braille input. We conducted a user study with 12 blind participants on Braille character discrimination. Results show that HoliBraille is effective in providing localized feedback; however, character discrimination performance is strongly related with number of simultaneous stimuli. We finish by discussing the obtained results and propose future research avenues to improve multipoint vibrotactile perception.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
