A Shape Recognition Benchmark for Evaluating Usability of a Haptic Environment
نویسندگان
چکیده
This paper describes a benchmark task for evaluating the usability of haptic environments for a shape perception task. The task measures the ease with which observers can recognize members of a standard set of five shapes defined by Koenderink. Median time for 12 participants to recognize these shapes with the PHANToM was 23 seconds. This recognition time is within the range for shape recognition of physical objects using 1 finger but far slower than recognition using the whole hand. The results suggest haptic environments must provide multiple points of contact with an object for rapid performance of shape recognition.

متن کاملApplication-Based Evaluation of Haptic Interfaces
A taxonomy of haptic modes is proposed as a basis for evaluating haptic interfaces. Haptic modes are defined as distinct styles of using haptic perception for purposeful activity. An evaluation method that exercises a single haptic mode tests the hardware and software of the interface on a task that has a clear relationship to actual applications. To demonstrate this approach to evaluation, the...
متن کاملCollaborative Evaluation of a Haptic-based Medical Virtual Environment
There is increasing use of virtual environments for medical training applications. Simulated medical environments allow clinical staff to practise medical procedures without endangering patients. Haptic devices are a key technology in many such systems adding a sense of touch to virtual interactions allowing healthcare practitioners to practise and test their clinical skills in life-like situat...
متن کاملKinesthetic Telepresent Control with Application to Disposal of Mines
This paper presents a novel approach to support disposal of explosive ordnances by application of bimanual haptic telepresent control techniques. For improved task execution the proposed system enables an operator to perceive multimodal feedback, in particular detailed kinesthetic and tactile feedback, from a remote task environment. Details of the developed experimental setup, comprising stere...
