....detectors are subject to physical noise (for example, any metal near a Polhemus tracker tends to have rather strange effects on its behaviour) and some software is still required for filtering. On the other hand, they consume little computing power (in fact one of the first gloves, the Z glove [ZL87] was attached to a Commodore 64 hardly a rival to a Cray) This means that cost can be kept down. It also adds to their portability and some of the gloves (such as the CyberGlove [KL89] have been road tested, while attached to small palm top computers. 2.6 Whole Hand Input Devices Much of ....

This was soon followed by a more regular device, which was later to become the VPL DataGlove [ZL87, ZL92] which is shown in figure 2.6. This device (which is, by the way, heavily protected by patent laws) was built by Thomas Zimmerman, who also patented the optical flex sensors used by the ....

....of human machine interaction. Currently, there are several available techniques that are applicable for hand gesture recognition, which are either based on auxiliary devices or computer vision. A typical widespread device based example is VPL data glove, which is developed by Zimmerman in 1987 [4]. In this system, user wears a VPL data glove that is linked to the computer. The glove can measure the bending of fingers, the position and orientation of the hand in 3 D space. Data glove is able to capture the richness of a hand s gesture. Its successful example is real time American Sign ....

In 1979, the put that there experiment [3] already used primitive gestural input. More recently, the availability of new devices to track hand gestures (such as the VPL Dataglove [19]) and the advent of virtual reality systems have popularized the concept of gestural input. The expected advantages of hand gesture input can be summarized as follows: Natural interaction: Gestural input makes use of the natural human communicative skills to interact with a computer.

....the person wearing the badge. Because IR is fairly directional and requires a relatively clear line of sight for reception, users desiring privacy can simply put the badge in a pocket, preventing the receivers from picking up the transmitted signal. Instrumented gloves, such as the VPL DataGlove [Zimmerman et al. 1987], Virtex CyberGlove, and Exos Dexterous Hand Master, provide information about finger joint angles. The DataGlove accomplishes this with a set of ten fiber optic cables, one for each of the first two joints of the hand s five fingers. Each cable is run in a loop along the back of its finger, and ....

The glove has specifically positioned flex sensors capable of recognising an 80 character superset of the Single Hand Manual Alphabet for the Deaf. By far the most successful glove is the VPL DataGlove, developed by Zimmerman [45]. The DataGlove is based on patented optical fibre sensors along the backs of the fingers, two for each finger. Like the Sayre glove, finger flexion bends the fibres, attenuating the light they transmit. This analog signal is sent to a processor which determines the joint angles based on ....

A therapist undertakes the painstaking process using a mechanical goniometer to obtain the range of motion for each individual joint. This process often takes hours to complete. ....
