在本文中，我们调查的位置的影响，振动触觉刺激在触发的反应，使用两个手持acrypticks。特别是，我们比较性能与刺激提供使用触觉放在手掌上或手背上，并与有吸引力的（走向振动）或排斥提示（远离振动）。实验装置包括两个摇杆和两个手套，每个摇杆和手套沿着基本方向配备有四个寻呼机马达沿着。在不同的区块中，53名志愿者被要求尽可能快地移动摇杆，或者朝向或远离一组振动马达指定的方向。结果表明，参与者在有吸引力的提示下表现得更好（即，在要求参与者沿感觉到的振动的方向移动摇杆的条件下，响应更快并且错误更少），并且从手套传递到手背上的刺激比由摇杆传递到手掌上的刺激给出更好的结果。最后，我们分析了偏侧性、正确反应与反应时的关系、错误反应的方向模式，并对刺激-反应相容性和训练效果进行了分析。
In this paper we investigate the influence of the location of vibrotactile stimulation in triggering the response made using two handheld joysticks. In particular, we compare performance with stimuli delivered either using tactors placed on the palm or on the back of the hand and with attractive (move toward the vibration) or repulsive prompts (move away from the vibration). The experimental set-up comprised two joysticks and two gloves, each equipped with four pager motors along the cardinal directions. In different blocks, fifty-three volunteers were asked to move the joysticks as fast as possible either towards or away with respect to the direction specified by a set of vibrating motors. Results indicate that participants performed better with attractive prompts (i.e., responses were faster and with fewer errors in conditions where participants were asked to move the joysticks in the direction of the felt vibration) and that the stimulation delivered on the back of the hand from the gloves gives better results than the stimulation on the palm delivered by the joysticks. Finally, we analyse the laterality, the relation between correct responses and reaction times, the direction patterns for wrong responses and we perform an analysis on the Stimulus-Response Compatibility and on the training effect.
