HAPTIC APPLICATIONS

1. Mid-air Haptic Display

● Non-Contact Airborne Ultrasound Haptic Display

 We are developing a technology that delivers haptic feedback to an arbitrary point in space using focused ultrasound waves. To enhance the focusing quality and intensity, we are advancing the technology of high-speed phase controllers and ultrasound actuators.

 


2. Reconfigurable shape-morphing and tactile display

We are developing a versatile shape-morphing and tactile display based on the reconfigurable electrohydraulic soft actuator. Based on the novel design and working principle, the developed shape-morphing display can provides enriched haptic feedback including dynamic tactile pattern, and localized surface texture with vibrotactile feedback.

Electro-active polymer (EAP) actuators, particularly dielectric elastomer actuators (DEAs), is a flexible soft actuator as a tactile element for wearable interface. With the developed wearable interfaces using DEAs, we can provide programmable tactile stimuli on skin. 


4. Hybrid haptic simulator for rendering car door

We are developing a hybrid haptic simulator to replicate the kinesthetic haptic interaction of car doors. Car doors are composed of various components that generate a combination of passive and active forces. To effectively simulate these dynamics, the system simultaneously controls both motors and brakes to reproduce the haptic sensations of different door models. The hybrid haptic simulator will be integrated with AI to analyze trends in driver perceptional responses to changes in physical factors. This approach enables the optimization of the haptic interaction experience of car doors, enhancing user satisfaction and interaction quality.


5. Haptic for Consumer Electronics

Not only for wearable devices, EAP actuators are also suitable for curved surfaces, such as car handles and other consumer electronics. Therefore, with EAP actuators, haptic touch panels can be implemented on consumer electronics. Our target is to make a consumer electronics with highly transparent panel.
