Abstract—Patient who is suffering hand tremor may find difficulty in performing handwriting task. Responding to this problem, the assistive pen is developed by examining the effect of proposing the Proportional-control in counter the hand tremor affect to the quality of handwriting. Experiments were conducted on an assistive pen placed on the experimental rig that will resemble actual hand tremor writing. The Linear Voice Actuator (LVCA) is used as an anti-tremor device. Based on real-time experiments result, proposed proportional controller shows an enormous potential on an assistive pen in counter tremor movement.
Index Terms—Assistive pen, proportional controller, linear voice coil actuator.
