Abstract
In the use of a laser pointer, tremor counteracts human's control and leads to less accuracy. The objective of this study is to develop a laser pointer with active suppression of the effect of user's tremor. We measured human tremor in the use of a laser pointer and analyzed it in time and frequency domains. As the result, difference in acceleration between in stationary and moving situations was clarified. This result leads to recognition of user's intention if he/she desires to keep or move the pointing position or not. Additionally, we proposed a control strategy to suppress user's tremor effect which combines feedforward based on BMFLC and feedback controllers. Result of the simulation applied this strategy showed its effectiveness.
