The telephone is the most ubiquitous computer input/output device with over 200 million units in the U.S. Thousands of applications – from airline reservations to zoo schedules – employ audio output and touch-tone input to control the flow and content of information. Because of the limited information capacity of the telephone, designing useful and usable phone-based interfaces presents a strong challenge to the designer. This paper will focus on the strengths and weaknesses of phone-based interfaces, present design guidelines, and discuss future directions.

Six Degree Of Freedom

A cable-suspended haptic interface (CSHI) concept is presented. The goal is to create an input/output device to provide six-degree-of-freedom (dof) wrench (force and moment) feedback to a human operator in virtual reality or remote applications. Compared to commercially-available haptic interfaces for virtual reality applications, the present concept is driving for lighter, safer, crisper, more dexterous, and more economical operation. The CSHI concept is presented, along with the required mathematical transformations for use of the device.

Control Implementation

This technical brief addresses issues of mechanical emulation of stiff walls and stick-slip friction with a 6-DOF magnetically levitated joystick. In the case of stiff wall emulation, it is shown that the PD control implementation commonly used severely limits achievable wall damping and stiffness. It is also shown that the perceived surface stiffness can be increased without loss of stability by applying a braking force pulse when crossing into the wall. For stick-slip friction, Karnopp’s model was implemented using a PD controller within the stick friction threshold. Even though the PD controller allows some motion during the stick phase, the haptic feedback provided is remarkably similar to stick-slip friction.
