Providing high resolution tangible user interface components without batteries such as dials and sliders that support dynamic user interface arrangement is challenging. Previous work uses RFID to support limited resolution custom-built components. We demonstrate improved techniques using commercial off the shelf input controls incorporated into passive RFID(More)
This paper presents a new mitten incorporating vacuum layer jamming technology to provide haptic feedback to a user. We demonstrate that layer jamming technology can be successfully applied to a mitten, and discuss advantages layer jamming provides as a wearable technology through its low profile form factor. Jamming differs from traditional wearable haptic(More)
The industrial design prototyping process has previously shown promising enhancements using Spatial Augmented Reality to increase the fidelity of concept visualizations. This paper explores further improvements to the process by incorporating tangible buttons to allow dynamically positioned controls to be employed by the designer. The tangible buttons are(More)
Layer jamming devices enhance wearable technologies by providing haptic feedback through stiffness control. In this paper we present our prototype that demonstrates improved haptic fidelity of a wearable layer jamming device, using computer controlled solenoid to enable fine-grained control of the garments stiffness property. We also explore variable(More)
We present a method for dynamic manipulation and interchanging of tangible objects in a spatial augmented reality environment for use in rapid proto-typing. We call this method MagManipulation. This method improves on existing methods in several ways: allows for the use of abstract and non-uniform curves, allows for ease of manipulation on non-tabletop like(More)
OBJECTIVE The articular cartilage of autologous osteochondral grafts is typically different in structure and function from local host cartilage and thereby presents a remodeling challenge. The hypothesis of this study was that properties of the articular cartilage of trochlear autografts and adjacent femoral condyle are associated with the 3-D geometrical(More)
