Figure 1: Twiddler2 Chording Keyboard and Isometric Joystick. RELATED WORK Our interaction techniques are based on Zeleznik s discussion [7] of 2D devices for 3D manipulation and navigation and Zhai s bulldozer navigation metaphor [8] They do not require direct reference to points on the display, which is difficult with eyeglass mounted wearable displays. We have also employed a tilt sensor in two of our 3D navigation methods. Tilt ....

.... generation of post WIMP interfaces that leverage application specific knowledge and human skills to realize a more powerful, natural, and task efficient user interface (e.g. see Fig 5) Examples of our recent work are 3D widgets [14, 3] free form deformations [24, 42] and gestural interfaces [60, 62, 61, 13]. 3D widgets demonstrate how parameters can effectively be represented by 3D geometry and embedded in a 3D dataspace. Our system Sketch [60] is a gestural interface for 3D geometric conceptual design which demonstrates that 2D drawn gestures can specify rich, context sensitive commands to realize ....

Our system builds on concepts from a number of researchers, including: Proprioception and the placement of objects relative to the body in [11] Viewing and manipulation of objects using the Worlds in Miniature [20] and Voodoo Dolls [17] techniques; Two handed 3D interaction techniques in [7] and [23]; Selection and manipulation techniques like the GoGo arm [18] and various others covered in [2] The WearTrack system and its variety of user interfaces in [6] Another existing powerful modelling system is MultiGen Smart Scene [12] which allows users to construct and manipulate objects in a ....

....[PIER97] that allow the user to manipulate the objects in the selection buffers. Image plane manipulations treat the objects as flat 2D entities, and map 2D movements of cursors into 3D transformations of objects. Any of the input devices can be used with this, and two handed manipulation [ZELE97] is particularly useful as the user can rotate or scale the object using one hand as a reference for the other. 6 Rendering system A major core component of Tinmith evo5 is the rendering system. It is a full hierarchical modelling system, similar to SGI s Inventor [STRA93] in that it implements ....

....attached to the cursor. Therefore, it is not possible to alter objects in directions the user is facing. Tinmith Hand may use any of the four cursors to perform image plane transformations on objects, although the two handed input gloves are the main method envisaged. Other previous work such as [2, 7, 19] also used two handed techniques to work in 3D environments. We have found rotation manipulation particularly well supported by two handed interaction techniques. By using two hands, the user can specify the orientation to apply based on the angle the hands form, and scale an object based on the ....

....with advantages in certain conditions. For example, techniques that use spotlights [17] gaining functions for movement [21] the image plane [20] and the aperture of a cone created by a tracker [11] can compete as mechanisms for selection at a distance, while two trackers [27] two pointer input [32] or proprioception [18] can compete to support object manipulation. Several authors have created evaluation techniques for these new ITs, in particular for tasks such as traveling [6] grabbing, and object manipulation [5] 16] 22] 23] Some of these studies have produced testbeds where the ....

....or its color as it is being created. 1 Deering used a mouse and a tracker to explore a similar two hand interaction technique [10] Others, have also explored two handed interaction and noted several advantages over one handed input when the two handed interface is designed properly [7] 18] [27]. The most compelling advantage to using two hands in this case comes when the glove and the brush are used simultaneously to paint one stroke that contains a smooth transition between multiple colors. Typically, artists use this technique by starting a stroke with the non dominant hand held ....

....The user can rotate and scale the diagram simultaneously by single dragging. If the cursor moves toward or away from the diagram s center, the diagram scales. If the cursor rotates around the center, the diagram rotates. 1 We assume one handed, single pointing device operation. Some systems [3] use two handed operation with a keyboard or another pointing device in the non dominant hand. Move Rotate Scale Moving the pivot Figure1: Integrated Manipulation. The user can move, rotate, and scale the diagram, and can move the pivot without mode switching. Figure2: The diagram rotates ....

.... University have recently demonstrated a 3D modeling interface that relies purely on gestural sketching of geometry and commands and has a vocabulary of over 20 gestures [9] they have extended this type of interface to twohanded interaction, a combination of techniques that shows much promise [8]. This system, Sketch [9] was used to create a 3D model of a baseball field in a matter of mere minutes (Figure 2) Sketch uses unconventional, non realistic rendering techniques to make the 3D model appear like an informal line drawing. The two car images depicted in Figure 3 show how an exhaust ....

....invocations with their orthographic counterparts. For example, to display the color wheel, the user gestures the letter C , and to invoke a snapping mode the user draws the letter S . A di erent approach to extending the functionality of a gesture system is to support two handed interactions[7]. The use of two hands e ectively increases the amount of context that can be provided for each operation. For example, when using two hands to control two independent cursors, it is a simple matter to specify both ends of a line segment simultaneously something which can t be done with a single ....

....to a good location [3] or the system may automatically initiate an animated camera change when it perceives that the user needs to be in a different location to perform an interaction task [4] Transitioning between camera techniques has been largely unaddressed in the literature. Zeleznik [8] discusses fluid gestural transitions between camera interaction techniques in a system related to UniCam that, however, requires two 2 DOF input devices. Gleicher also enables elegant transitions between camera manipulations using Through the Lens Camera Controls [2] controls that enable a ....
