The CM can recognize new constraints, enforce existing constraints and validate applied constraints. It is part of a more complex VR system [Fernando00 ] Fernando01] Murray02] that supports assem assembly and disassembly operations in immersive ....

....to aid interface designers in constructing effective interfaces for virtual environments. 1. Introduction Previous research into the development of usable Virtual Environment (VE) interfaces has shown that applying 2D techniques can be effective for tasks involving widget manipulation [12, 5, 6]. It has also been shown that the use of physical props for manipulating these widgets can provide effective feedback to aid the user [13, 11] In some cases, however, it is not practical to require the use of physical props because of real world constraints, such as a cramped workspace, or the ....

....have been employed to support interaction in 3 space. Glove interfaces allow the user to interact with the environment using gestural commands [9, 8, 3] Laser pointer techniques provide menus that float in space in front of the user, and are accessed using either the user s finger or a 3D mouse [14, 15, 6]. With these types of interfaces, however, it is difficult to perform precise movements, such as dragging a slider to a specified location, or selecting from a pick list. Part of the difficulty in performing these tasks comes from the fact that the user is pointing in free space, without the aid ....

In Fish Tank virtual reality, where the user s head is tracked while viewing a more conventional display [Deering93] or a virtual workbench [Cutler97], latency in the graphics causes objects to swim or shear as the result of user head motion. The non desirable side effects of latency have motivated us to examine techniques for reducing latency and to study how much system latency is perceptible by human users. The conventional 3D graphics ....

Many types of menus have been developed for use in VEs (Angus Sowizral, 1995; Jacoby Ellis, 1992; Mine, 1997; Mine, Brooks, Sequin, 1997) but none of them simultaneously address the issues of efficient, comfortable, and precise selection of a large number of menu items.

There are many examples of both commercial and academic versions of such systems. Recent examples include the Responsive Workbench [2], the ImmersaDesk [4] the Immersive Workbench [5] and the Visionmaker PS [12] We have added a force feedback device to such a display, whose working volume is superimposed on the visual display volume. This adds the dimension of touch; the user can not only see and point at virtual objects but ....

....but only a few systems use two handed manipulations on a single object. Polyshop [11] uses symmetric two handed tools for rotating, scaling, or stretching objects. Users can also align objects via anchors and constraints. The CHIMP system [12] uses two hands for object scaling. Cutler et al. [6] developed a variety of two handed tools for object positioning tasks. They also presented two versions of a two handed grab tool, which allowed them to orient objects easily using two hands, and to pass objects from one hand to the other. There is a variety of constraint based systems. One of ....

We are just beginning to explore the types of software tools and interfaces that might further assist such collaborative interaction. Cutler et al.
