Interface Selection

Chapter

After the decision for the actuator (chapter 9) used to generate the haptic feedback, and after the measurement of forces (chapter 10) or positions (chapter 11), it becomes necessary to focus on the IT-interface. This interface has to be capable of providing data to the actuation unit and catch and transmit all data from the sensors. Its requirements result - such as with any interface - from the amplitude resolution of the information and the speed at which they have to be transmitted. The focus of this chapter lies on the speed of transmission, as this aspect is the most relevant bottleneck when designing haptic devices. Haptic applications are frequently located on the borderline, may it be with regards on the delay acceptable in the transmission, or the maximum data rate in the sense of a border frequency.
