We deep dive today into the ISWC 2024 best paper award.
Tactile feedback mechanisms enhance the user experience of modern wearables by stimulating the sense of touch and enabling intuitive interactions. Electro-tactile stimulation-based tactile interfaces stand out due to their compact form factor and ability to deliver localized tactile sensations. Integrating force sensing with electro-tactile stimulation creates more responsive bidirectional systems that are beneficial in applications requiring precise control and feedback. However, current research often relies on separate sensors for force sensing, increasing system complexity and raising challenges in system scalability. We propose a novel approach that utilizes 3D-printed modified surfaces as the electro-tactile electrode interface to sense applied force and deliver feedback simultaneously without additional sensors. This method simplifies the system, maintains flexibility, and leverages the rapid prototyping capabilities of 3D printing. The functionality of this approach is validated through a user study (N=10), and two practical applications are proposed, both incorporating simultaneous sensing and tactile feedback.
