Disclosed is a method for a knuckle pointer for simultaneous keyboard/handwriting control. Benefits include improved usability and improved performance.

Background

              The keyboard does not map to the complete screen interface. With some personal digital assistant (PDAs), adding a keyboard requires the user to either add a mouse or pick up a stylus every time a field is selected. Other tablets, with build in thumbwheels have similar problems. For, example, tablets with right handed scrolling wheels and pen interfaces require right-handed users to put down the stylus to manipulate the wheel. Then, when a user has set the screen view appropriately, the user must let go of the wheel, pick up the stylus, and tap a few things on the screen.

Description

              The disclosed method is a knuckle pointer that consists of a ring with a variable-length pointer attached. The ring is a band worn on the index finger of the user’s natural writing hand. The pointing device tip is smooth so that it does not scratch the touch-screen surface. The ring band is approximately 0.5 inches long and fits between the base and middle knuckle (see Figure 1). By making a fist, the pointing device is available for moving the curser on the screen like a traditional stylus.

              The pointing device has a slight cut-away allowing its underside to clear the top of the middle knuckle so that finger movement is unobstructed. The pointer is placed slightly off center from the top of the ring. The pointer is moved towards the thumb so it can gently pinch the band to secure the pointer. By p...
