The key to touch-enabling very small devices is to use touch on the device backside. In order to study this, we have created the 2.4” prototype device shown below; we simulate screens smaller than that by masking the screen.

The key to touch-enabling very small devices is to use touch on the device backside. In order to study this, we have created the 2.4” prototype device shown below; we simulate screens smaller than that by masking the screen. In a user study, participants completed a pointing task successfully across all (2.4" to 0.3") display sizes when using a back-of device interface. The touchscreen-based control condition (enhanced with the shift technique), in contrast, failed for screen diagonals below 1 inch. A second study provides design guidelines for practitioners who want to design for back-of-device interaction (details: paper draft).
