Input amplifcation enables easier movement in virtual reality (VR) for users with mobility issues or in confned spaces. However, current techniques either do not focus on maintaining feelings of body ownership, or are not applicable to general VR tasks. We investigate a general purpose non-linear transfer function that keeps the user's reach within reasonable bounds to maintain body ownership. The technique amplifes smaller movements from a user-defnable neutral point into the expected larger movements using a confgurable Hermite curve. Two experiments evaluate the approach. The frst establishes that the technique has comparable performance to the state-of-the-art, increasing physical comfort while maintaining task performance and body ownership. The second explores the characteristics of the technique over a wide range of amplifcation levels. Using the combined results, design and implementation recommendations are provided with potential applications to related VR transfer functions.
