Interaction through programmable soft materials
Abstract:
Shape-changing user interfaces (UIs) have been increasingly studied in human-computer interaction (HCI) due to their ability to adapt the interaction to data, tasks, environment, and users. The emergence of programmable soft materials has enabled HCI researchers to design soft, shape-changing UIs with high flexibility. Soft materials like silicone have attracted HCI researchers’ interest due to their compliance with the human body for wearable applications and their remarkable shape-morphing ability. However, little is known about users’ ability to perceive the shape of soft shape-changing UIs and the impact of UIs’ softness on users’ shape perception ability. Moreover, the possibility and challenges of building soft, shape-changing UIs have hardly been discussed.
This Ph.D. thesis addresses three main research questions: (1) How do users perceive soft shape-changing UIs? (2) Which soft shape-changing UIs can be developed, and what are the challenges? and (3) What can soft shape-changing UIs be used for? Firstly, a psychophysical experiment is conducted to study users’ shape perception ability with surfaces under different softness. Secondly, the possibility and challenges of constructing shape-changing interfaces with soft materials are explored. In particular, a new technology is proposed to build soft shape-changing UIs with strength tunability. Lastly, two case studies are presented: The adaptation of the shape of the surface at the back of a mobile phone following the demonstration of the asymmetric efficiency of dominant and non-dominant hands at the back of the device and the study of the perception of a soft shape-changing surface at the back of a smartwatch.
