....easily perform additional non navigation tasks with their hands. Widget based controls are also popular for navigating within virtual environments. The most relevant widget to our work is Pausch s implementation of a navigation technique based on flying into a hand held world in miniature (WIM)[11]. This technique allows a user first to indicate a desired new viewing location using a handheld miniature representation of the virtual environment, and second to be seamlessly flown to that location by an animated transformation of the hand held WIM. The primary disadvantage of this and most ....

The small sphere by the user s foot indicates his position in the miniature. which was used for selecting and manipulating virtual objects[14] as well as navigation and locomotion[11]. However, instead of treating the WIM as a hand held object, we wanted to achieve an effect similar to walking through a miniature environment landscape, such as Madurodam in The Hague. Consequently, when a user invokes the Step WIM, a miniature version of the virtual environment is placed ....

A number of techniques for 3D interaction have been developed, including object selection 97a] flying, grabbing and manipulating [RH92] worlds in miniature [PBBW95] combination of different modes of speech, gesture and gaze at the interface to allow real time interaction with a graphics display, two handed interaction 97, CFH97] and exploiting proprioception [MBS97] Among them, haptic visualization, as an augmentation to visual display, has the ....

To notify the user that this is happening, we first replace the registered world overlay with the WIM model, but at full scale and properly registered. Then the WIM is interpolated in scale and position to its destination configuration [25]. This animation provides useful information that makes it possible for the user to orient herself with respect to her current position in the WIM. Additional spatial orientation help is provided by the introduction of the avatar, which is highlighted for a few seconds. Figure 6 shows the UI just ....

To notify the user that this is happening, we first replace the registered world overlay with the WIM model, but at full scale and properly registered. Then the WIM is interpolated in scale and position to its destination configuration [25]. Figure 4 shows the user interface just after this transition. Because the head body alignment is relatively constant between these two pictures, the position of the projected WIM relative to the display is similar in both pictures, but the differing position and orientation of the body ....

....of the scene. These views are usually larger views of the database used both to give the user a better understanding of the environment he is moving in, and to help navigation by producing map like information. These extra views can be displayed either on separate viewports, or in the same one [2, 6, 15, 17]. An alternative consists in allowing the user to scale the virtual world down to a miniature, selecting a new viewpoint, and then rescaling the miniature world back up using the newly selected viewpoint [8, 3] ffl A second approach provides the user with objects attached to the viewpoint in ....

Unlike the WIM [15], it seems that this operation isn t perceived by the user as disorienting. The reason may be that the user doesn t see a camera icon but the view which is passed to the main view. The Magic Mirror, together with these functionalities has been tested for different tasks. We have identified five ....

This technique is most appropriate for close examination of single objects from different viewpoints, e.g. interior design (see Fig. 5) ffl scene in hand: this is the complementary technique to eyeball in hand. Sometimes this can be quite useful for orientation or coarse object placement [23]. ffl Sometimes it is desirable to be able to control the viewpoint without hands .

....The Step WIM is a miniature version of the world that is placed on the ground, under the user s feet in the virtual environment. The idea is derived from Stoakley s hand held World In Miniature which was used for selecting and manipulating virtual objects[21] as well as navigation and locomotion[16]. However, instead of treating the WIM as a hand held object, we wanted to achieve an effect similar to walking through a miniature environment landscape, such as Madurodam in The Hague.

....to navigate to a specific place by simply walking to a desired location in the WIM and invoking a scaling command, causing the Step WIM to animate scaling up around the user s feet 1 , thereby seamlessly transporting the user to the specified virtual environment location. As Bowman[1] and Pausch[16] discuss, animation of the Step WIM is essential to the user s sense of location. In situations where the Step WIM is either too large or too small, the user can, upon command, increase or decrease the size of the wim. 3.1 Invoking, Scaling and Dismissing the Step WIM In addition to the effect ....

....effects of changes since the scale of the user and world are different, a small motion by the user results in a large motion in the world. Another idea employing scaling is to have two copies of the world, one large and one small. In the World in Miniature (WIM) technique (Stoakley, Conway, and Pausch, 1995), the user manipulates small objects in a dollhouse world held in the hand, and the corresponding full size objects move accordingly. This has been extended in the recent voodoo dolls technique (Pierce, Stearns, Pausch, 1999) in which the user creates his own miniature parts of the ....

....this assumption was the NASA Ames VIEW system [Fisher] Users could create a window that looked into a different location; when they resized that window to fill their view the system actually teleported them to that location. Pausch used a similar idea for navigation using a handheld miniature [Pausch95]. To move to a different location the miniature grows and moves so that the user occupies the desired position in the expanding miniature. When the miniature reaches 1:1 scale the system teleports the user to that position in the virtual world. Pierce breaks this assumption in a different way ....

....AND USER TASKS IN VES 53 An interesting implementation of the scene in hand metaphor, discussed previously, is the WIM developed at the University of Virginia [UVA, 1996] The WIM is a miniature representation of the VE. When users move objects in the WIM, the corresponding virtual object is moved [Pausch et al. 1996]. If desired, the WIM can contain a graphical representation of user position and orientation (typically a camera and viewing frustum) that can be manipulated to specify new user locations and orientations. When specifying new locations via virtual object representation, the immersive world must ....
