Abstract
Described herein are techniques related to a leveled touchsurface with planar translational responsiveness to vertical travel. Examples of a touchsurface include a key of a keyboard, touchpad of a laptop, or a touchscreen of a smartphone or tablet computer. With the techniques described herein, the touchsurface is constrained to remain in a level orientation during planar translational movement between depressed and unpressed positions along a diagonal line with respect to a vertical axis. Also, with the techniques described herein, a planar-translation-effecting mechanism imparts a planar translation to the touchsurface while it travels vertically (e.g., downward) as the user presses the touchsurface. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
