Haptic Interface for Non-Visual Steering
… significant cause of traffic accidents. Existing haptic automotive interfaces typically indicate when and in which direction to steer, but they don't convey how much to steer, as a driver typically determines this using visual feedback. We present a novel haptic interface that relies on an …

Novel haptic interface For viewing 3D images
… an input to be rendered in a 3D display, do the haptic rendering calculations and have a position depending render of the scene. The author presents two main contributions. First, since the haptic devices have a finite work space and limited resolution, we used what we call detail mapping …

Interactive freeform solid modeling with haptic interface
… the issues of interactive solid modeling with haptic interface. A virtual reality (VR) approach is taken to make the use of modeling tools more intuitive and interactive. The virtual sculpting method is based on the metaphor of carving a solid block into a 3D freeform object. The VT interface …

Haptic interaction with three-dimensional bitmapped virtual environments.
… of a system integrating a force-reflecting haptic interface, the PHANToM, with a high-powered computer designed to efficiently compute cellular automata, the CAM-8. My goal was to build a system to allow users to interact with three-dimensional bitmapped simulations running on the CAM. Such …

Digital Control Techniques for High Fidelity Haptic Simulation Systems
Haptic simulation systems allow human users to kinesthetically interact with virtual environment models through a robotic mechanism known as a haptic interface. The sampled-data nature of haptic interfaces limits the range of virtual environment dynamics that can be stably rendered in a haptic …

Characterizing motor control signals in the spinal cord
… lever press task they are trained in. A haptic interface and wireless neural data amplifier system simultaneously collects dynamic and neural data. Isometric force is predicted from force signal using a combination of time-frequency analysis, Principle component analysis and linear …

A haptic control system for functional electrical stimulation of paraplegic legs
… a useful manner. The system proposed here uses a haptic interface, one that utilizes the sense of touch, attached to a user's index and middle fingers. The haptic device allows the wearer to feel with the fingers what would normally be felt by the feet. Movement of the fingers is monitored and the …

Development of a force-feedback laparoscopic surgery simulator
… available. A survey of the issues surrounding haptic (touch) displays and training for laparoscopic or "keyhole" procedures was performed. A number of primary and secondary sources including surgeon consultation , operating room observations, and task analyses were used to accumulate a list of …

Haptic controls in cars for safer driving
… geared towards utilization of the human senses, haptic technologies have been introduced as a way of utilising the sense of touch to either solve real world problems or to enhance present experiences. This thesis focuses on using haptic technology in cars to make the driving experience safer. …

A demonstration and comparative analysis of haptic performance using a Gough-Stewart platform as a wearable haptic feedback device
… other modes of sensory such as auditory or haptic. The University of Texas at Austin's TeMoto hands-free interface reduces the burden on the operator of commanding remote systems by enabling the use of gestural and verbal commands to complete a range of tasks, but the removal of a mechanical …

Craftsmanship and automation in flexible metal spinning
… wisdom of experienced spinning craftsmen using a haptic interface. The validity of the rules is confirmed by a statistical analysis of the results of over 70 experimental trials with craftsmen. Control of both the roller force and the workpiece shape are found to be fundamental for the craftsmen …
