Multi-sensory haptic cues have the potential to transmit a wider variety of information in the same amount of time as single-sensory haptic cues. However, these cues also interfere with each other, causing them to feel less salient to users. As it is critical that the multisensory cues transmitted to a user are conspicuous, we use the AIMS Testbed to investigate the perception of multisensory haptic cues and how this perception changes when cues are modified. This project will inform future interations of wearable haptic devices to produce distinguishable and clear multisensory haptic cues to users.
