Many research projects have been conducted to compare standing text entry with nomadic text entry. Other research projects have compared the input types of touchscreen and physical keyboards while texting. There is few literature that compares the two inputs types during a standing and nomadic text entry. This research was conducted to investigate the differences in error rate and characters per minute for both input types during both text entry conditions. To investigate these differences two devices were used, the iPhone 4 and the Blackberry Curve 9350, to type a phrase during both a standing and walking condition. Both characters per minute and error rate were analyzed. The investigation showed that there were no significant difference in error rate, but there was a significant difference in characters per minute. The touchscreen keyboard performed better in terms of characters per minutes and arguably performed better in accuracy.
