Working memory are closely related to everyday cognition (such as remembering the conversation and characters). Studies with hearing, vision stimulation have always been carried out, but studies using tactile stimulation are very little. However, tactile working memory is the ability to reproduce the functionality of the somatosensory system. It is very relevant to elucidation of the somatosensory system and intellectual impairment of tactile. Moreover, Visual and Auditory task have possibilities affect education and living environment, such as number, language and so on. On the other hand, tactile stimulation task can research human cognition without the problem. However, tactile stimulation is presented by hand, so study of tactile working memory does not consider pressure information and influence result. Moreover, Active region of brain is changed from time to time in working memory, it must be considered too. Memory in order to investigate the tactile working memory, device for considering the pressure information and to present the tactile stimulation on constant conditions is indispensable. In this Study, we developed and evaluated a device for tactile spatial research in high magnetic field environment. Consideration to advanced research on fMRI environment in the future, we developed device in High magnetic field environment.
