Weisenberger, M. J. Krier, M. A. Rinker, Haptics-e, The electronic journal of haptics research, Vol. 1, No. 4, March, 28, 2000.1545-1143http://hdl.handle.net/1773/34882The ability of observers to resolve the orientation of virtual gratings presented on two different haptic interfaces was investigated. Gratings were presented either with the 2-degree-of-freedom Immersion IE2000, or with the 3-degree-of-freedom SensAble Devices PHANToM. Results showed excellent resolution of both sinusoidal and square-wave gratings with both devices. Possible factors that may have influenced the results, such as force models, force vectors, and end effectors, are addressed.en-USArticle
