Harmonizing a projected user interface

A method for adapting a property of a projected user interface based on at least one property of a surface on to which the projected user interface is projected, the method comprising:

• determining the at least one property of the surface;
• determining a relevant user interface setting based on the determined at least one property of the surface;
• and
• applying the determined relevant user interface setting to the projected user interface, such that the property of the projected user interface is changed according to the determined user interface setting,
• wherein the projected user interface is updated such that at least one of animations or sound effects of the projected user interface appear to match the at least one property of the surface, wherein:
• on a less deformable surface, a pressed button results in a hard surface animation;
• and
• on a more deformable surface, a pressed button results in a soft surface animation.

A projecting device for projecting an interactive user interface onto a surface and for adapting a property of the projected user interface based on at least one property of the surface, the device comprising:

• a projector configured to project the user interface onto the surface;
• a sensor configured to determine the at least one property of the surface;
• and
• a processor configured to:
• determine a relevant user interface animation based on the determined at least one property of the surface, wherein the determined relevant user interface animation appears to match a physics of the surface;
• and
• control the user interface projected by the projector such that the updating of the projected user interface in response to the user interaction with the elements of the projected user interface is applied according to the determined user interface animation based on the determined at least one property of the surface.
