We describe an object-oriented constraint solving toolkit, QOCA, designed for interactive graphical applications. It has a simple yet powerful interface based on the metric space m...
We have built a system that allows users to naturally manipulate virtual 3D models with both hands on the Responsive Workbench, a tabletop VR device. Our design is largely based u...
We have developed a MultiMedia Visual Information Seeking (MMVIS) Environment that is the first system to support an integrated approach to the direct manipulation specification o...
Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation may be used to conv...
A framework of complementary behavior has been proposed which maintains that direct manipulation and speech interfaces have reciprocal strengths and weaknesses. This suggests that...
