PROTO-TAI: Quick Design Prototyping using Tangible Assisted Interfaces

In the real world, we use our innate manual dexterity to create and manipulate 3D objects. Conventional virtual design tools largely neglect this skill by imposing non-intuitive 2D control mechanisms for interacting with 3D design models. Their usage is thus...
PuppetX: A Framework for Gestural Interactions With User Constructed Playthings

PuppetX: A Framework for Gestural Interactions With User Constructed Playthings

We present PuppetX, a framework for both constructing playthings and playing with them using spatial body and hand gestures. This framework allows users to construct various playthings similar to puppets with modular components representing basic geometric shapes. It...
Shape-It-Up: Hand Gesture Based Creative Expression of 3D Shapes Using Intelligent Generalized Cylinders

Shape-It-Up: Hand Gesture Based Creative Expression of 3D Shapes Using Intelligent Generalized Cylinders

Abstract: We present a novel interaction system, “Shape-It-Up”, for creative expression of 3D shapes through the naturalistic integration of human hand gestures with a modeling scheme dubbed intelligent generalized cylinders (IGC). To achieve this...
Extended Multitouch: Recovering Touch Posture & Identity Using Depth Cameras on a Pen+Touch Tabletop Interface

Extended Multitouch: Recovering Touch Posture & Identity Using Depth Cameras on a Pen+Touch Tabletop Interface

Abstract: Multitouch surfaces are becoming prevalent, but most existing technologies are only capable of detecting the user’s actual points of contact on the surface and not the identity, posture, and handedness of the user. In this paper, we define the concept...
