Abstract
A lot of products of the function that people can operate by touching a screen circulates. Based on the factor, a lot of people can use touch panel devices more widely. On the other hand, there are problems about tach panel devices. It problems are that users cannot feel how you operate tach panel devices, because tach panel devices are flat surface unlike normal buttons and switches. I think this problem is important, because users’ feedback is important by users and manufacturer. We suggest the interface of buttons and switches which is easy to get feedback by users.
