Pop Through Button Devices For VE Navigation and Interaction
This paper presents two devices: the FingerSleeve and the TriggerGun, which are aimed at providing pop through buttons to allow more interaction with virtual environments. This kind of research has already been led on desktop mouses for instance. Here, the finger pressure is used to control the environment, letting the hands of the user free.
Pop through buttons have three states. The hard thing is to make the user being perfectly able to choose the state. The TriggerGun looks like a joystick and has two pop through buttons, one for the index finger and the other one needing a finger to move. The FingerSleeve is to be put on the index finger and uses a tracker with six degrees of freedom. The two buttons are close but the distance between them should be shortened.
These pop through buttons have been used for three techniques. First, ZoomBack displays a laser which can point to objects and make the user move to them. Second, LaserGrab uses the same principle as ZoomBack but allows the user to choose the place he wants to end and if he wants to be in orbital mode. Finally, Snapshot allows users to take pictures, where they can travel to once taken. Also, the FingerSleeve has been tested in CavePainting to replace the Pitch glove as a simpler device, which satisfied testers.
Thus, these two devices allow many actions with their four states while remaining easy to deal with. Users where indeed happy with their use of ease. However, a major breakthrough will be to make these devices wireless for a better immersion. Another step will be to allow additional techniques by spotting intermediate states where only one button out of two is released. Finally, the design and dimensions could be enhanced for a better comfort.
