Using Periodic Systems to Model Hand-Haptic Interface Coupling

Design of Cylindrical Whole-Hand Haptic Interface Using Electrocutaneous Display

Precise manual work is frequently required in remote and virtual environments. Cutaneous feedback to the whole hand is a key element in achieving this goal; however, most haptic I/O systems for the hand only present haptic sensations to the tips of the fingers. I propose to use an electrocutaneous display to construct a whole-hand cutaneous feedback system. The display shape is cylindrical, to ...

Haptic interface transparency achieved through viscous coupling

Electromagnetic drives are subjected to an inherent inertia-torque tradeoff that fundamentally limits transparency: the higher the torque, the higher the inertia. We describe a dual-stage design that is not subjected to this tradeoff and that is able to approach perfect transparency for human users. It comprises a large, proximal motor and a small, distal motor to reproduce the transients. The ...

Simulation of the Admittance Control Based Haptic Interface Device

A Haptic Thermal Interface: towards Effective Multimodal User Interface Systems

Despite powerful sensory inputs (e.g., tactile and force feedback), haptic interface systems are still in an early stage of development for accomplishment of a high degree of realism. One of the key elements missing is the ability to present thermal information, such as the thermal conductivity and temperature of an object being manipulated. This real time information is one of the obstacles to...

Haptic Interaction Rendering Technique for HIRO: an Opposite Human Hand Haptic Interface

HIRO (Haptic Interface RObot) is a new device that enables users to interact and feel the virtual object safely. Hand interaction with virtual object requires a more elaborated model than the Haptic Interaction Point (HIP) due to the complex shape of the virtual hand. This paper describes a general haptic rendering of 3D object for hand interaction that takes in consideration the real shape and...
