Abstract: A system has a contactless user-interface through which a user controls a functionality of the system. The contactless user-interface has a detector sub-system and a user-feedback sub-system. The contactless user-interface has an alert mode and a control mode. In the alert mode, the user-feedback sub-system has a display monitor to provide a visible acknowledgement to the user, in response to the detector sub-system having detected the presence of the user within a an alert range. The contactless user-interface transitions from the alert mode to the control mode in response to the detector sub-system detecting an initialization gesture of the user. In the control mode, the contactless user-interface controls the functionality in response to the detector subsystem detecting a control gesture of the user. The visible acknowledgement is made to mirror the movements of the user.

Abstract: A display mechanism for showing search results, which is well-suited to displaying programming events on an electronic program guide, selectively aggregates items in result lists according to features having identical or similar values. Each aggregated item is represented by a respective symbol. A user interface may be provided to permit the selective expansion of the symbols. The resulting list has much less repetition than a list according to the prior art in which each search result is shown explicitly.

Abstract: A sorting mechanism sorts results utilizing one or more sort keys selected based upon the user task context, the content type relating to the items being sorted, and/or user-preferences. Intuitive or default sort keys such as program/song title are selected based on the user's objectives as inferred from task parameters or user selection of primary sort keys, but may be changed by the user, with the results are displayed in an ordered listing based on the sorting with the selected sort keys.
