説明

As one kind of new input device or new information exhibition device, haptic devices representing a tactile feeling of the object are actively researched in recent years. However, existing haptic devices bring some discomfort due to attaching certain devices to fingers, or they need the dedicated exclusive apparatus and panels. Therefore, in this study, we propose a haptic device which can express hardness of the virtual object using solenoid. By simply putting the traditional touch panels such as smartphones or tablets on this device, the device can represent a tactile feeling. The device reproduces reaction force to fingers by displacement of the object according to control voltage of the solenoid, and expresses hardness of the virtual object. As a result of the preliminary experiment measuring the reaction force on prototype device, we show that it is possible to control reaction force using solenoid. In addition, for example of application using this device, we design a software keypad that adds the feel of buttons in image displayed on the touch panel. As a result of this case study, compared with the case not changing the hardness of the imaged buttons, we demonstrate that the case changing the hardness by using our device can finish inputting numbers faster and can reduce the miss ratio of the key typing.
