Malleable Interactive surfaces for distant mobile tangible interaction

Abstract : Sliders are one of the most used widgets to control continuous parameters - e.g., brightness, sound volume, the temperature of a smart house, etc. On mobile phones, sliders are represented graphically, requiring the user's visual attention. They are mostly operated with a single thumb. While large sliders offer better performance, they present areas difficult for the thumb to reach. This article explores different tangible slider designs to offer eyes-free and efficient interaction with the thumb. The novel designs that we explored are based on a design space encompassing graphical solutions and the unexplored tangible solutions. To evaluate our designs, we built prototypes and experimentally tested them in three experiments. In our first experiment, we analyzed the impact on the performance of the tangible slider's length: either within the thumb's comfortable area or not. In our second experiment, we analyzed the performance of an extensible tangible design that allows operation within the comfortable area of the thumb. In our third experiment, we analyzed the performance of a bi-modal deformable tangible design that allows operation within the comfortable area of the thumb, and beyond this area, with the index finger on the back of the device. This work contributes to the literature by: first, providing a design space for one-handed interaction with deformable tangible elements. Second, analyzing the impact on performance when manipulating tangible sliders outside the thumb's comfortable area. And third, analyzing the impact that deformation has during manipulation.
