Integrating Haptic Feedback into Mobile Location Based Services
Haptics is a feedback technology that takes advantage of the human sense of touch by applying forces, vibrations, and/or motions to a haptic-enabled device such as a mobile phone. Historically, human-computer interaction has been visual - text and images on the screen. Haptic feedback can be an …

Tissue classification from electric impedance spectroscopy for haptic feedback in minimally invasive surgery
Haptic feedback is missing in teleoperated surgical robots creating a sensory disconnect from the surgeon and their patient. This thesis proposes using the electric impedance of tissues, instead of the traditionally used mechanical impedance, to develop haptic feedback for surgical robots. Electric …

A body-grounded kinesthetic haptic device for virtual reality
Kinesthetic haptic devices can make us feel that we are touching or holding objects that are not actually there by applying a force directly onto a user's body. As a corollary of Newton's third law, these devices are typically attached to the ground or else they would not be able to apply a net …
