A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R. A mixed model analysis was used to analyse the data. The model to estimate what impact button size has on time is found to be poor while the model to estimate accuracy is assumed to be good. Results show that a button size larger than 6.0mm is required for the average user to have satisfactory accuracy.
