Bird: A Point Cursor for Virtual Immersive Environments

Abstract

This paper introduces the Bird, a novel point cursor for immersive virtual environments (IVEs) that enables precise, one-handed control over a point in 3D space beyond arm’s reach. Interaction techniques commonly used in VR today lack this functionality. While direct manipulation allows for control of the position of an object in 3D space, it is limited to arm’s reach. Ray-casting enables interaction at a distance but specifies a line rather than a point, making it impossible to move objects closer or farther without additional mechanics. The Bird overcomes these limitations by allowing users to select any visible object and place it anywhere within view, with one hand and without requiring a controller. We explore a range of use cases that highlight the Bird’s potential to expand the design space for spatial computing.
