Patent application numberDescriptionPublished
20090140989User interface - The invention relates to a user interface for controlling an electronic device. The user interface includes a sensor element that has a sensor surface and is arranged to form a location indicator that indicates a location of a spot of the sensor surface that is closest to an external object. A force sensor is arranged to form a force indicator that indicates strength of a force directed to the sensor surface. A processor unit is arranged to control the electronic device on the basis of the location indicator and the force indicator. A user of the electronic device is enabled to control the electronic device by using different levels of the force directed to the sensor surface. Therefore, the electronic device can be controlled with a smaller number of repetitive pressing and release actions.06-04-2009
20100039832Changing Graphics in an Apparatus Including User Interface Illumination - An apparatus includes a light guide. A first light input section receives light in a first direction into said light guide. First direction-dependent outcoupling structures selectively couple out light propagating in said first direction in said light guide. A second light input section receives light in a second direction into said light guide. Said second direction is different than said first direction. Second direction-dependent outcoupling structures selectively couple out light propagating in said second direction in said light guide.02-18-2010
