Haptistylus: Akma ve dönme hissi verebilen elektronik kalem

With the emergence of pen-enabled tablets and mobile devices, stylus-based interaction has been receiving increasing attention. Unfortunately, styluses available in the market are all passive instruments that are primarily used for writing and pointing. In this research, we describe a novel stylus capable of displaying certain vibro-tactile and inertial haptic effects to the user. Our stylus is equipped with two vibration actuators at the ends, which are used to create a sensation of up and down flow along the stylus. The stylus is also embedded with a DC motor, which is used to create a sense of bidirectional rotation about the long axis of the pen. Through two psychophysical experiments, we show that, when driven with carefully selected timing and actuation patterns, our haptic stylus can convey flow and rotation information with high accuracy. Results from a further psychophysical experiment provide insight on how the shape of the actuation patterns effects the perception of rotation. Finally, experimental and subjective results from our interactive pen-based game show that our haptic stylus is effective in practical settings.
