Survey of Techniques to Increase Accuracy of Touch Screen Devices

The objective of this project is to conduct exploratory research into the effort of increasing accurac on touch screen devices. Graphical password schemes have been proposed as a possible alternative to text-based schemes. Human can remember pictures better than text, thus may contribute to a more positive user experience. Graphical password techniques include recall-based click password (e.g. imposing background image so user can click on various locations on the image), and recognize-based selection password (e.g. selecting images or icons from an image pool).
