Recently mobile devices that install a tilt sensor as an input device increased. The tilt sensor has a potential to free the users from complicated button operation. However a small monitor is not enough for quick and accurate tilt control. The purpose of this study is to test if the combination of haptic feedback and tilt sensor might improve the usability of mobile devises. We developed a prototype system providing the haptic feedback over pitch and roll movement of the device. Every inner side of the device contains a solenoid. The reaction force is generated from the impact of the solenoid against the inner wall, and the direction of the force is the perpendicular to each wall. Two type haptic feedbacks; STOP and NOTCH feelings, are available by controlling impact speed of the solenoid. We also developed prototype applications that apply proposed haptic feedback to operations of menu and scroll bar. For example, the STOP feedback is presented when the scrollbar hits a window frame.
