Current virtual simulation techniques often include multi-user interactivity in an environment which can be controlled in real time. These simulation systems are mostly used in military training sessions and in real time gaming experiences, where users have to make more strategic decisions by analyzing the information they receive, in response to the actions of other users in the same virtual environment. In real world, generally, collaborative decision making happens when a team of people work together to control the behaviour of a single object that a single person cannot handle alone. A ship with its crew can be held as an example. When applying this scenario into virtually simulated environments, several users have to involve in representing a single object in the virtual world. Thus the subordinate users need to obtain sufficient information about the activities in the environment in real time that will help to make collaborative decisions. Although users tend to depend on visual and audio based information, use of traditional static visual displays limits the capability of providing rich visual information about the 3D environment the object is mapped into. Conventional static displays are used because of the limitations of Head Mounted Displays such as ergonomic conditions and cost. This work is focused on exploring how Smart devices can be used by a subordinate user to accomplish the task of providing visual information to the main user, beyond the boundary up to which a static display can provide. To serve the above purpose, we propose a solution, “Virtual Eye”, which uses a Smart mobile device with the ability to view the visual output of the virtual world and the ability to control that view according to user's orientation changes and movements with the use of its inbuilt sensors.
