We present a new handheld multi-actuator haptic device, which provides localized vibrotactile feedback in a small form-factor. To isolate the vibrations generated from the different actuators, we design an original 3D printed deformable structure integrated into the handle. We evaluate the benefits of our isolation structure in a vibrometry study, comparing the proposed version to a rigid structure. A perception study is also conducted to evaluate the distinct perception of vibrations between the two versions of the handle by 12 human users. Finally, we showcase the use of the proposed handle in a virtual navigation task, showing its capabilities for applications where multiple and distinct haptic stimuli need to be provided to the user’s hand.
