WYSIWYP – "What You See Is What You Press" 
Describes the concept underlying a innovative, patented Chordic Graphical User Interface (CGUI) that can be used to control a wide range of mobile devices. It involves the principle whereby on-screen buttons or icons (called indicia) are mapped to one or more digits of the hand. Each indicium represents a user initiated instruction or input which is displayed in a one-to-one correspondence with the keys. In essence, the spatial arrangement of the graphical components indicates which combination (called a chord) of one or more digits, and thus which respective one or more keys, are to be activated in order to produce a particular action.

The CGUI is intuitive and easy to learn (demos). Once mastered, the CGUI permits the user to understand any screen of controls or options presented to them. It has some specific advantages over conventional input methods. Little or no visual concentration is required; once a particular software navigational path is learnt, haptic muscle memory enables the user to remember the chord sequences - not unlike a musical instrument. It is fast and intuitive, no carefully tracking a cursor to a pull-down menu, selecting, releasing, etc. Conventional pointing devices such as mice require a unique visual/physical effort for every selection, a chordic input merely requires the simple motor action of articulating the fingers. Being visual the learning curve is negligible, and any new screen is always manageable in much the same way that a mouse once understood is forever useable.

The input device requires only one hand and the compact nature of the CGUI makes it feasible to include it in numerous hand-held devices eg; mobile phones, remote controllers, camcorders as well as wearable and mobile computers. Other applications may possibly extend to Non-Roman character input devices and the physically challenged.
