We attempt to create a dynamic keyboard for mobile phones that will change depending on the direction of finger movement. The idea is to create a vector between the last pressed button and the current position of the finger. All buttons touched by this vector will be enlarged to give the user a greater area to select. The vector extends all the way across the keyboard to ensure all buttons beyond the one currently touched are also resized. We hope to achieve a lower error rate using these dynamically changing buttons.
To realise this we will make simulate the finger tracking by creating a prototype in which the use swipes from one button to the next, realising their finger from the screen to select the button they are touching. We compare two prototypes, one with and one without dynamically changing buttons.
