ImpAct : Haptic Stylus for Shallow Depth Surface Interaction

ImpAct is a tool which enables users to interact with surfaces using their natural affordances. It is a specialized haptic stylus designed to access the shallow depth area of a touch surface and interact with the 3D digital space with kinesthetic haptic feedback. Usage of ImpAct can be analogous to manipulating an object inside a fish tank using a stick. User perception of ImpAct can be seamlessly submerged in the digital space in order to make direct contact with and manipulation of the digital environment. ImpAct consist of a scalable stem, making it possible to change its effective length when it is pushed against a screen. Simultaneous to these changes in the physical stylus, a virtual stylus is rendered inside the digital space below the screen surface aligned to the axis of the physical stylus (Simulated Projection Rendering). ImpAct is integrated with a force feedback motor to provide haptic sensations to users when they interact with digital objects. With ImpAct, the user has a visually continuous interface to digital space and multidimensional interaction possibilities with haptic feedback, which is "through surface interaction", a new interaction paradigm for surface computing. In the future, ImpAct can be used as a physical tool for modeling, texturing and manipulation in 3D design applications. It also has promising applications as a new gear for gaming, or as a tool in the medical industry for both diagnostics and remote surgery. As we presented, ImpAct is capable of creating non-trivial interaction possibilities and novel application scenarios for surfaces, specially with 3D applications.
