Executive Summary Introduction The Robot Prototype is designed to test the user knowledge in term of understanding the task requirements to be performed. It tests the user in terms of the reaction, which may conclude if the user found enough information in the interface to deal with requirement. Three Prototypes are generated to test the user performance. The first Prototype (Prototype 1) is a command line prototype which is, an interface showing the user the relative position of the cave walls (up, down, left or right) and requiring the user to take action to move the Robot to avoid colliding with it. The second Prototype (Prototype 2) interface shows the user the relative position of the Robot and gives instructions how to avoid the cave walls. The third Prototype (Prototype 3) is a graphical interface, which shows the user picture of the relative position of the Robot and the cave wall and gives...
