Purpose of this study is to clarify the requirements of the design for user interface using ‘haptic feedback’ generated from active touch to the solid three-dimensional shape. The haptic feedback is the key function to enhance the user's sense of agency in the interaction environment. This is an enhanced study based on the “Ridge Line UI”, that had been presented by author. However, the role of the haptic feedback in the user interface is different. In this study, haptic feedback is used to match the “predicted sensory feedback” and “actually sensory feedback”. In order to design such user interface, the three concepts (“consistency of time” and “real-time performance of haptic feedback” and “introducing of proprioceptive sense”) are introduced. Through the mock-up and self evaluation, these concepts are confirmed whether they act effectively to design that enhances the correspondence between the palm position and the transition of things.
