Abstract:

The popularity of smartphones, mobile electronic devices and many types of information appliances is driving the demand for touch screens.Our Embedded project is to design and develop a low cost feature which is based on embedded platform using ARM architecture. Generally touch screens accept the tapping method for typing the messages, typing methods for small touch screens is still worth studying.Smartphone users facing the difficulties for typing on small touchscreens and experiencing errors in typing the alphanumeric keys bacause of their thick thumbs.Small virtual keypad provides very tiny sizes of keys even with the redused set of keys.So partial keyboard layout requires many number of switches between different layouts.This paper studies a new typing methods Drag-and-Type and Secure Drag-and-Type. In the Drag-and-Type method uses the dragging action for typing the messages instead of direct tapping on the small touch screens. The Secure Drag-and-Type metod is used for secure password entry against shoulder surfing and spyware attacks in the normal tapping methods.The typing speed is controversial, but Drag-and-Type method used when the accurate typing is required.Here we are using the GSM modem to transfer the messages to any number.This method is proposed for improved performance, accurate and secure password entry on the small touch screens for security sensitive appliances.
