UI Design | Gestural Interactions

For my first year master thesis I wanted to investigate gestural interactions with smartphones further, and specifically with 3D touch actions or force touch actions.


Apple introduced the 3D touch technology in 2015. It's a technology that senses how deeply the users presses the screen. With 3D touch, iPhone users can access apps and complete tasks quicker, and draw using pressure sensitivity. However, support for this technology is only available on Apple iPhones and are limited to certain apps and Apple’s own built-in functions. The support limitation along with the trend of flattening mobile user interfaces contributes to the difficulty to show and to discover the 3D touch actions. Thus, my thesis work explored ways to make possible 3D touch interactions more visible.

The thesis project touches on topics such as multi-touch and gestural interfaces, force gestures, affordances, feedforward and hinting. Using an interaction design process involving methods such as surveys, observations, lo-fi and hi-fi prototyping and usability testing, I investigated the area further. This with the aim of designing a way to enhance the visibility and accessibility of 3D touch interactions.
