| Description | This paper describes various techniques of accessing objects hidden behind obstacles in virtual environments. Obstacles can be any larger virtual objects or a group of smaller objects. To interact with occluded objects, a user must move around the obstacle to a location where the situation can be seen more clearly. We show some of well known interaction techniques that are suitable for usage in this case. Next, we describe new method, Head Manipulator, for manipulation with an user's location and new aid that allows user to change the visibillity of objects. We propose several combinations of these interaction techniques and tools, and discuss their suitability for the given task. For every method we show its advantages and drawbacks and we say for what situations the method is useful. Subsequently, we describe our experiments when testing these methods and then we conclude with the results from the experiments and from users' observations. |
