Abstract Direct manipulation using pointing devices commonly relies on basic interaction tasks such as selection and precise cursor positioning. Traditionally, such tasks use geome...
A framework of complementary behavior has been proposed which maintains that direct manipulation and speech interfaces have reciprocal strengths and weaknesses. This suggests that...

Object alignment is one of the basic operations in drawing programs. Current solutions provide mainly three ways for carrying out this operation: either by issuing an alignment co...
Oscillatory motion is ubiquitous in computer graphics, yet existing animation techniques are ill-suited to its authoring. We introduce a new type of spline for this purpose, known...
In current commercial feature modeling systems, support for direct manipulation of features is not commonly available. This is partly due to the strong reliance of such systems on...
This paper presents a system for graph clustering where users can visualize the clustering and give "hints" that help a computing method to find better solutions. Hints ...
Abstract. This paper reports on user experience with Tioga, a DBMScentric visualization tool developed at Berkeley. Based on this experience, we have designed Tioga-2 as a direct m...

Direct manipulation involves a large number of interacting psychological mechanisms that make the performance of a given interface hard to predict on intuitive or informal grounds...
It is often difficult in computer graphics applications to understand spatial relationships betweenobjects in a 3D sceneor effect changes to those objects without specialized visu...

In this paper, we present techniques for integratingconstraint and direct manipulation approaches to geometric modeling. Direct manipulation positioning techniques are augmented t...
