Haptics in Training

Surgery, Driving Simulator, Flight simulators



Why and where Haptics?Cost• Materials used are expensive• Tools used are expensive

The tools/ materials are hard to transport/ store

Skilled teachers are hard to find

Task involves skill developed over a long period of time

Safety is a significant concern


Haptic device design challenge

Keeping haptics cost effective : high forces and large workspaces make device design complicated and hence expensive.

• Need of Expert• Safety measures• Cost of Tool• Portability• Technique intensive, Skill intensive

Tool Selection Criteria for

Haptic simulation

• Type of Grasp: Contact, Precision, Power• Workspace• Degrees of Freedom – x,y,z (translation, roll)

• Degrees of Force feedback – x,y,z (translation, roll)

• Posture while working • Powered or Non Powered Tool
