Hyunyoung Kim - Conception centrée utilisateur de dispositifs physiques changeant de forme

Shape-changing interfaces bring flexibility in physical interfaces through by transform- ing computational devices into any shape or materiality. Shape-changing interfaces will be increasingly available to end-users in the future, along with technology devel- opment. However, we know little about design criteria of shape-changing interfaces for end-users, especially for whom use parameter control interfaces. Parameter con- trol interfaces are often designed based on existing examples such as dials and sliders, and there were few studies to understand user needs behind their usage. On the other hand, there are shape-changing interface taxonomies that allow designers to explore design ideas of shape-changing interfaces systematically, but they are hardly evaluated. In this talk, I discuss my Ph.D. work investigating the two areas of HCI: parameter control interfaces and shape-changing interfaces. I first conduct a forma- tive study to suggest design requirements for parameter control interfaces based on users’ current practice. Second, I refine a shape-changing interface taxonomy by eval- uating its descriptive power by using everyday reconfigurable objects. Lastly, I look into the intersection of the parameter control interfaces and shape-changing inter- faces. I develop two case studies: KnobSlider, a shape-changing interface that can be a knob or a slider, and ExpanDial, a rotational control that extends the interaction modality through shape-changes.
