Abstract [en]

Mixed Reality (MR) is a technique to blend together the real life with virtual reality. Using this technique it is, for instance, possible for experts to assist persons several miles away to perform tasks by talking and  visually aid them. In this thesis the main issue is to see how the delay in such a system for remote assistance eects the users.

A controlled test was carried out with 20 test persons of dierent backgrounds. The study shows that it is very likely to be able to use an MR system for remote assistance even if there is a delay between the user and the expert. As long as they both are aware of the problem and are able to take it easy and do not have to move around too much it is still possible to work with delays to up to 4000 ms.

Furthermore, the average time of completion for a task did not increase with the added delay. It was linear, i.e. the task is not more difficult toperform when the instructions are delayed.
