Open Thesis Topics
Vibrations provided by our smartphone inform us about notifications and events through our sense of touch. By coupling vibrations with user actions such as applying pressure on a surface, one can create illusions of a click (e.g., Apple ‘Force Touch’ trackpad) or change the perceived features of the surface (e.g., softness). While there is a large body of existing research investigating this vibrotactile feedback, designing such structured tactile messages remains a challenge. Leveraging better non-visual cues when interacting with graphical elements on touch user interfaces (UI) would lead to more refined and subtle interaction techniques.
For this thesis, you will build a tool to design vibrotactile effects for graphical touch UIs. Using this tool, a designer should be able to load a UI element and create and refine vibrotactile effects using direct manipulation techniques. These approaches could be similar to existing approaches such as vocalizations , and build on existing vibrotactile libraries  or parametric design tools . This design tool could support building novel touch feedback for the web , thus creating novel opportunities for designing web interactions. Using the created design tool, you will perform a user study investigating the differences in design approaches.
This work focuses on mobile design. The choice of supporting libraries and toolkits remains open for discussion with the supervisors.
