Abstract [en]

This thesis is a literature study on how existing research on embodied tool use may support the use of the use of the computer mouse within three dimensional environments, followed by an analysis of a typical scenario in the use of three dimensional environment. Problems with interaction in this domain are well known to designers of 3d programs but not well understood, which results in programs in which mouse controllers are used to control three dimensional objects being more difficult to learn and less efficient to use than would be possible if the interaction was better understood. The problems are often identified by their symptoms, such as the drag-threshold problem, picking problem, and the object rotation/viewpoint management problem, but this thesis will explore what the cause of those problems is, and identifies them all as a single cognitive problem which is found to be caused by a rift between the functioning of the two dimensional tool in use (the mouse and cursor) and the simulated three dimensional environment with which the cursor is interacting. Analyses are performed on a scenario, and result in a pinpointing of the problem and possible solutions to the interaction part of the problem (with design guidelines emerging), as well as finding the possibility that the cognitive roots of the problem result from an incompatibility between body-schema frames of reference for movement between the two dimensional parts of the action and the three dimensional part of the action.
