With the ever-increasing popularity of cell phone devices, text based services on such devices are becoming more and more popular. Problems with traditional keypads primarily lie with the placement of the letters alphabetically on the keys. This configuration is comparatively easy for the users to remember but can greatly limit the flexibility of finger movement, as well as require a higher number of keystrokes and key jamming. In attempting to resolve these issues, a novel innovative solution is proposed here, focusing on both the structure of human finger movements and ordering of letters on the keys based on their frequency of use. Simulations and performance measurement of our represented system have shown rapid reduction in key jamming by up to 57 percent, improvements in flexibility of finger movement by up to 11.5 percent and reduction in number of keystrokes by up to 34 percent. © 2011 IEEE.
