Disclosed is a method and apparatus, applied to eyewear that incorporates computing capabilities, for controlling the cursor using two small, identical controller devices attached to adjacent fingers. This approach allows the user to perform computing directives without the need for an associated flat plane upon which to place the fingers.

Finger Controllers for Computing Eye Wear

As eyewear products that incorporate computing capabilities further develop , the difficulties of the logistics for adapting the use of a computer incorporated into a person's eyewear remain. In typical computer usage, a person must be able to select items, scroll, select text, drag, and perform other actions that require control of a system cursor. Tracking eye movements provides some element of cursor control ; however, additional input is needed to provide a comprehensive solution . Consider a person

wearing a pair of computing eyeglasses. The cursor control options available on a touch screen device are not readily available on a pair of eyeglasses .

A method is needed to provide such additional input through a cursor controller for eyewear that incorporates computing capabilities.

In one approach to permit control similar that that available on a touch screen , the user

wears a small device on a finger, in the form of a ring or a finger cap, that incorporates a camera or other technology capable of detecting finger movement relative to a surface. In such an embodiment, the finger is used to control the cursor and make selections, as it is on a touch screen device. This is an interesting and useful embodiment; however, it limits the user to scenarios in which the user's finger has ready access to a stable surface against which they can move a finger , and it assumes that random finger movements can be somehow differentiated from those intended for cursor control.

A more interesting scenario is that in which a user has no surface upon which to work ; for instance, a user might be having a discussion with a colleague while standing in a hall, or may be searching for information while walking down the street.

The novel contribution is a method and apparatus for controlling the cursor in 'free space'. With this approach, a pair of small devices, worn on adjacent fingers, can control the cursor for computing eyewear to provide all necessary functionality , while eliminating the random or unwanted actions that can occur if a single such device were employed.

Two small, identical controller devices are attached to two adjacent fingers . The devices are asymmetric, having a working orientation with a specified area nearest the fingernail, and a 'front' area facing the end of the finger. For instance, in one embodiment, the devices are shaped as rings, with an opening on one side. In this embodiment, the opening is worn over the fingerprint area of the finger , and the ring has a 'front' worn toward the finger tip, creating a top, bottom, right, and left relative to the hand. This arrangement orients the devices relative to the hand and wrist such that, if the fingers are moved downward with the palm facing down, the direction detected is the same if that motion is performed with the palm facing up . This allows the user to act as if the interaction is with a plane that can be variably oriente...
