Cursor Control using Smartphone in Large Display Space

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