This chapter examines a range of technological solutions to the problem of recording interaction between children and products. Logging the activities of children is an attractive option for usability studies. These methods are unobtrusive and can often run alongside other evaluation activities. Some methods need special treatment when used with children but, in general, the use of these methods is relatively straightforward although care must be taken, especially when recording children, to ensure that the logging method does not interfere with the interaction of the child with the product. The technologies used for evaluation are normally used alongside or as part of the evaluation methods. The technologies covered include automated logging of interactions, video and audio recording, and gaze tracking. Automated logging involves recording the user's inputs to a system in a way that is not intrusive so that the user's actions can be examined or analyzed later. Video and audio technologies have obvious applications for recording users' reactions in observation studies, but they can also be used in interviews as an alternative to simultaneous note taking and in usability tests as a convenient method of recording task completion times. Gaze-tracking technologies can be used to record where users are looking as they perform tasks. |
