optical methods of tracking human movement

Optics may also be used to track our movement. An elementary method of optical tracking involves attaching several light sources to a glove or body tights and then monitoring their movements in three-dimensions. Nonetheless, this only tracks a narrow quantity of points. Gesture interpretation by computing systems currently happens. It involves computer simulation of the configuration of hands, arms, and face -- integrating concepts across the fields of anatomy, kinesiology, and human visual processing. Link to From Geography to Reality provides more material about this.

Touch and motion based interaction from computers to human beings is the result of work on motion and touch, but it is less developed than haptic communication from humans to computers. Humans feel things through several methods. Macroscale information concerning the locations of parts of the body comes from proprioceptors that track muscle contraction and expansion. Besides information about body location, this information response provides macroscale information about object attributes (such as size, shape, weight and motion) built on the relative resistance that the object brings to movement of human fingers, arms, etc. We all also get small scale information about attributes of things such as texture, moisture, and temperature. This small scale feedback comes from mechanoreceptors in the skin. Link to Virtual Tours Maplewood, Minnesota provides additional information on this topic.
