Leveled touchsurface with planar translational responsiveness to vertical travel

A human-machine interaction (HMI) apparatus comprising:

• a touchsurface configured to be presented to a user to facilitate, at least in part, human to computer interaction therethrough by the user depressing the touchsurface;
• a leveling mechanism operatively associated with the touchsurface, the leveling mechanism being configured to constrain the touchsurface to a level orientation while the touchsurface travels downward as the user depresses the touchsurface;
• a planar-translation-effecting mechanism operatively associated with the touchsurface, the planar-translation-effecting mechanism including one or more ramps that are configured to impart a planar translation to the touchsurface while the touchsurface travels downward on the one or more ramps as the user depresses the touchsurface.

• a leveling mechanism operatively associated with the touchsurface, the leveling mechanism being configured to constrain the touchsurface to a level orientation while the touchsurface travels downward as the user depresses the touchsurface, wherein the leveling mechanism includes one or more ramps positioned under and/or around the touchsurface so as to ameliorate and/or eliminate wobbling, shaking, rotating, and/or tilting of the touchsurface while the touchsurface travels downward as the user depresses the touchsurface;
• a planar-translation-effecting mechanism operatively associated with the touchsurface, the planar-translation-effecting mechanism being configured to impart a planar translation to the touchsurface while the touchsurface travels vertically, wherein the planar-translation-effecting mechanism includes at least one inclined plane down which the touchsurface rides while the touchsurface travels downward as the user depresses the touchsurface, the at least one inclined plane being configured to impart the planar translation to the touchsurface while the touchsurface travels downward as the user depresses the touchsurface.
