We introduce a one-handed travel technique for virtual environments (VE), we call Phone-Based Motion Control. The travel technique uses a mobile phone with integrated sensors as a 3D spatial input device. We benefit from the touch capability to change the viewpoint translation in the VE, while the orientation of the viewpoint in the VE is controlled by the built-in sensors. The travel interaction clearly distinguishes between translation (touch based translation control) and rotation (steer based rotation control), putting each set of degrees of freedom to a separate interaction technique. This work examines how many degrees of freedom are needed to perform the travel task as easy as possible. It also investigates different mapping functions between the user's actions and the viewpoint reactions in the VR. For that purpose, four metaphors are developed for the steer based rotation control technique. The results of the user study indicate the trend that 4 DOF metaphors perform best, and that the usage of a mobile roll to control the viewpoint is the desired mapping.
