SPIDAR-S: A Haptic Interface for Mobile Devices
In order to introduce the haptic technology to more common users outside the academic sphere, this paper proposed a haptic device SPIDAR-S which is able to be attached to mobile devices such as smartphones and tablet PCs. The proposed device provides a user with one degree of freedom force feedback in the way of pulling one of the user’s index fingers with a string which is driven by a micro motor. Audio signals are adapted as the control signal for the motor’s output torques. Because of its simple structure and compacted size, SPIDAR-S is supposed to be taken around as a portable accessory for mobile devices, enabling a large number of users to enjoy haptic implemented applications in an easier and more casual way.
