For the first experiment, all in all 40 workers were recruited and divided into two groups of 20. With the first group of workers the aim was to measure and compare their performance in doing an assembly activity while they accessed explanatory paper-based information, and when this information was accessible through wearable technology. The workers had to per-form the complete assembly task as fast as possible and only once. By means of the second group of workers it was intended to evaluate how wearable technology can contribute to the training process. A prerequisite was that the workers had to learn how to complete the proposed activity. This involved that they had to perform the full process, until they were able to perform the activity without any kind of support. As the “short-term memory factor” was to be measured as well, the workers had to perform the same task one day later, without any kind of support.
In both cases the workers had to perform the experiment twice: once using paper based support and second using one of the three interaction modalities which were proposed randomly: textile keyboard attached to the sleeve, speech commands and non-explicit or context based interaction.
In the second experiment the 20 participants had to perform the assembly task as fast as possible three different assembly layouts, each of them using a different information access mechanism: 2 HMD (we already had the data using the third HMD from the previous experiment) and the big monitor.
