Abstract—We present a novel approach as a smartphone based interface that enables the users to control the cursor position in large display space. In the proposed method, computational techniques using image processing and accelerometer processing methodology serves as the core engine for fine cursor control. Unlike previous positioning mechanisms based on image processing, the proposed system is free from restraint of movement with velocity. For the implementation of our system, we combine the block matching algorithm for optical flow with three-axis acceleration to improve an accuracy and clutch.
