Abstract

Twelve users with a range of ages between 20 and 70, were assessed for their cognitive capabilities and degree of experience with microwave cooker features and then trialled with two microwaves, one with a dials interface and the other with a buttons interface. The users were provided with a set of tasks to complete with each microwave. It was hypothesised that all users would perform better with the dials model but that the difference in performance between dials and buttons would become more pronounced as age increased. This was found to be the case in comparing the performance from the trials, with the strongest correlation occurring between the users age and the time taken to complete the tasks.
