A novel tactile softness display for minimally invasive surgery
The use of Minimally Invasive Surgery (MIS) in various types of surgical procedures has increased significantly in recent years. However, its scope is limited due mainly to the fact that this procedure does not currently provide tactile feedback without which the surgeon can neither feel nor palpate tissue. In this paper, we describe a new tactile display that reproduces these missing constitue...
متن کاملA New Softness Display Interface by Dynamic Fingertip Contact Area Control
A new softness display system has been developed which controls the fingertip contact area dynamically according to the detected contact force, based on the human softness recognition mechanism. The relative softness cognitive rate of four levels softness using the developed system was 98 percent while ten volunteers touched the device actively. The absolute softness cognitive rate, the rate of...
متن کاملTactile Flow and Haptic Discrimination of Softness
Haptic perception involves both cutaneous perception, through mechanoreceptors lying on the skin, and kinaesthetic perception mediated by the position of the fingers. Analogously, artificial devices should replicate both these perceptual channels, as well. While kinesthetic information is satisfactorily replicated by current technology, cutaneous information is still a challenging task to be pr...
متن کاملPresentation of Softness Using Film-Type Electro-Tactile Display and Pressure Distribution Measurement
Electro-tactile display has simple mechanical structure and it can present tactile stimulus. However, electro-tactile display lacks of feedback corresponding to touching motion. In this research, we developed a device that combines an electro-tactile display and pressure distribution sensor. The device not only solves problem of unnatural electrical sensation, but also enables expression of hap...
متن کاملA dielectric elastomer actuator-based tactile display for multiple fingertip interaction with virtual soft bodies
This paper presents a novel wearable tactile haptic display for rendering soft body sensations to multiple fingertips with electroactive smart elastomers. The system uses newly developed multi-layered hydrostatically coupled dielectric elastomer actuators (DEAs), which have been designed to apply a localised tunable force to a user’s fingertip via a soft electrically-deformable interface. The s...
