Deformable User Interfaces (DUIs) often require external confirmation of the status of the interface, which is normally provided visually. We propose that tactile cues can also be employed for this end. In a user study that presents both visual and tactile cues in redundancy, we found that both channels can be combined with no loss in user experience or performance. This validates our design for further research on multimodal designs that make use of no redundancy in the supporting cues.
