Most mobile devices offer a range of methods for inputting data, for example, touch screen, stylus, keypad and voice command. We’ve already looked in some detail at touch screens. Most mobile devices use a virtual keyboard for input, but some have physical keyboards. Blackberry phones (which are specifically designed for handling mobile email) generally have keyboards and the Asus Transformer range of tablets have a keyboard dock which effectively turns the tablet into a laptop. Some devices also offer the facility to use a stylus for input. The Samsung Galaxy Note comes with a suite of applications, called the Premium Suite, designed for use with a stylus. The Suite provides seven templates for a for a range of common tasks, including writing a diary or jotting down notes. You can record each step of your drawings and play them back, use the device as a whiteboard to create diagrams and flowcharts or annotate and save PDF.
