 Introducation Data Glove Computer Graphics

Data gloves are devices equipped with sensors that capture the movements of the hand of the user in order to select or manipulate objects in a virtual world. Data gloves were introduced three decades ago and since then have been used in many 3D interaction techniques. However, good data gloves are too expensive and only a few of them can perceive the full set of hand movements. In this paper we describe the design of an image-based data glove (IBDG) prototype suitable for finger sensible applications, like virtual objects manipulation and interaction approaches. The proposed device uses a camera to track visual markers at finger tips, and a software module tocompute the position of each finger tip and its joints in real-time. To evaluate our concept, we have built a prototype and tested it with 15 volunteers. We also discuss how to improve the engineering of the prototype, how to turn it into a low cost interaction device, as well as other relevant issues about this original concept.

What does Dataglove mean?

A dataglove is an input device that is essentially a glove worn on the hand that contains various electronic sensors that monitor the hand's movements and transform them into a form of input for applications such as virtual reality and robotics. Some datagloves enable tactile sensing, allowing the user to seemingly feel a virtual object and to apply fine-motion control.

A dataglove is used to capture physical phenomena, such as the bending of fingers, as data. It also often contains a motion tracker such as an inertial or magnetic tracking device that captures the position and rotation of the hand/glove. These movements are then interpreted by a driver or software made specifically for the glove so that the gestures can be converted into an input for a separate program such as for virtual reality, games or for controlling animatronics or other kinds of robots.

A data glove is an interactive device, resembling a glove worn on the hand, which facilitates tactile sensing and fine-motion control in robotics and virtual reality. Data gloves are one of several types of electromechanical devices used in haptics applications.

Tactile sensing involves simulation of the sense of human touch and includes the ability to perceive pressure, linear force, torque, temperature, and surface texture. Fine-motion control involves the use of sensors to detect the movements of the user's hand and fingers, and the translation of these motions into signals that can be used by a virtual hand (for example, in gaming) or a robotic hand (for example, in remote-control surgery).

Within a virtual reality room or other VR environment, a data glove can allow you to interact normally with objects -- turning doorknobs, for example -- and receive haptic feedback to replicate grasping a doorknob and feeling the object in your hand rather than just making a gesture in air. Haptic feedback is essential to immersiveness, which enables user engagement in virtual environments, particularly for applications like VR gaming.
