What is “Haptics Haptics”?
Haptic: Related to “Touch”
–Originated from the Greek “haptesthai”
–Refers to both “Tactile”and “Kinesthetic”senses
•Haptics: An emerging interdisciplinary field for
–Understanding the human haptic sensory and motor characteristics, and
–Developing a computer-controlled system that allows us to physically interact with a virtual or remote environment through touch
Benefits of Haptics
•Virtual Reality
–Increased realism
–Another input/output modality
•Teleoperation
–Hazardous environment
–Non-accessible environment
•Information Display
–Increased information transfer bandwidth
–Effective in sensory-saturated environment
Surgery Simulation
Safe and risk-free training for surgeons
•Laparoscopic Surgical Workstation
–Immersion Corp.
–5 DoF
Insertion
Pitch
Yaw
Handle twist
Handle grip
Multi Multi-Attribute Haptic Rendering
•Haptic rendering is not perfect!
•Possible interplay among renderer’sefforts for multiple object properties?
•Simultaneous Rendering of Collocated Surface Stiffness and Topography
–Topography perception can be distorted due to varying stiffness with the current haptic rendering methods
–It is due to force constancy that the user exhibits when exploring a virtual surface in order to perceive its topography
Haptic Watermarking
•Watermark
–Data/signals that are imperceptible or perceptible under very limited and specific conditions
–Used to hide information such as copyright
•Haptic Data + Watermark
•Reference
Summary
•Haptics is concerned with our sense of touch.
•Haptics is a relatively new and quickly growing interdisciplinary research field.
•Haptics is fun
