Due to demand, I decided to provide some information on the set-up of my experimental work during the evaluation stage of MGUIDE. The information below is the briefing participants had to read for experiment 4. Please note, that the main technique for data collection in experiment 4, is think aloud protocol. I conducted the testing with two user groups of 6 participants.
The purpose of this experiment is to investigate the possible effects of two mobile systems for path finding of variable complexity, on your ability to find your way in the castle. You will have to use the systems to navigate along two different routes visiting a number of landmarks in turn (10 to maximum 18), using the system A on one, and the system B on the other. The total duration of the experiment doesn’t exceed 20 minutes per route. For the purpose of the experiment I have created two video applications representing in detail each route of the castle. At each video-clip you will hear the question “What would you do at the particular point, if you were in the castle?” You must answer the question based on the visual (i.e., gestures and landmarks) and/or audio instructions delivered by the system.
For example:
Given this instruction:From where you are, if you look on your right, you will see two chimneys. Opposite the chimneys there is a path that leads to another square. Please follow this path until you will come across a house with a black front-door!
And this clip:
You will have to answer: “I will follow the path on the right of the tree until I see the house with the black front-door”. The next video will show the result of this action (i.e., that you have moved towards the house with the black door), and will pose you a new navigational challenge.
