(2021-2022) Holitouch: Integration of tactile feedback, proprioceptive feedback and pseudo-haptics to improve the haptic realism of essential 3D user interface elements such as buttons. This approach is based on a wearable device that combines different types of haptic feedback to convey the holistic sensation of stiffness, contact, and activation while interacting with 3D buttons. It provides these sensations by utilizing redundant multisensory cues, i.e., congruent feedback, to create plausible illusions of touch.

(2018-2019) Analysis of proximity-based multimodal feedback for 3D selection in VR. The feedback was provided through the visual, auditory and tactile modalities, while users perform 3D object selections in VR. Both binary and continuous proximity-based feedback affected the ballistic and correction phases of the selection movements. As a result, the feedback influenced the user performance (throughput) significantly, and could be used to reduce depth over/under estimation in 3DUIs.

(2015-2017) Development of haptic technology for 3D interaction; digital fabrication and evaluation of different (wearable and wireless) devices to provide tactile feedback on a finger-, hand-, and foot- basis. The feedback can be modulated according to distances/positions, or can be encoded based on material properties when a collision is detected with a virtual object. All the devices are compatible with motion tracking systems supporting sub-milimeter precision.
