The J-K Computer Keyboard


The J-Keyboard eliminates the mouse in most text (i.e. non graphic) environments.

Benefits are:

  1. Increases productivity. No need to lose time moving the hand to and from the mouse.
  2. Reduces footprint. No need for the space occupied by the mouse pad.
  3. No retraining. Identical functionality to a mouse.
  4. Cost saving. Both the cost of the mouse, and the mouse port, is eliminated.

How Does It Work?

When typing, the home keys for the Index and Middle fingers of the Right Hand are the J and K keys. These keys are modified to enhance their functionality and eliminate the mouse.

Imagine you are typing, and you need to use the drop-down menu system for an editing function.

  1. Press both the J and K keys simultaneously, and momentarily. This switches the keyboard from “Typing Mode” to “Mouse Mode”.
  2. The cursor jumps to the middle item of the Menu Bar at the top of the screen.
  3. Applying a difference in pressure exerted by the Index and Middle fingers on the J and K keys provides the user with a Left / Right “Rocker” Control of the Cursor. This is used to intuitively move the cursor Left or Right horizontally along the Menu Bar to the desired Menu Bar Item.
  4. Releasing both the J and K keys selects the Menu Bar Item.
  5. The cursor jumps to the middle item of the Drop Down Menu chosen.
  6. Touch or proximity sensors along the top and bottom edges of the J key, or a force direction sensor incorporated in the J key, provides an Up / Down Control of the Cursor. This is used to intuitively move the cursor Up or Down Vertically along the Drop Down Menu, to the desired item.
  7. The selection is validated by a single (or double) press on the K key, to mirror normal mouse functionality.
  8. Further Sub Menus are navigated in a similar intuitive fashion.
  9. If there are no further Sub Menus for a given selection, the “Mouse Mode” is cancelled after the last selection is made. The Menu Bar reverts to its inactive state,and the keyboard reverts to “Typing Mode” and functions as a normal keyboard.
