Abstract: Systems, devices, and methods described herein provide an input device having keys operatively coupled with light devices that emit light out of the keys. The input device is associated with different modes of operation. The light devices emit the light out of the keys responsive to a selected mode of operation being a first mode of operation. The light devices stop emitting the light out of the keys responsive to the selected mode of operation being a different, second mode of operation. The light devices are activated to indicate the selected mode of operation. One or more processors perform first functions associated with the keys during the first mode of operation and perform different, second functions associated with the same keys during the second mode of operation.

Abstract: A convertible self-checkout system includes a base and a stand rotatably mounted to the base. The stand includes an input/output device facing in a first direction and a product scanner, and the stand is positionable relative to the base in at least a first angular position and a second angular position. The input/output device is an interactive video display, and the interactive video display has a first mode corresponding to the first angular position and a second mode corresponding to the second angular position. A sensor determines an angular position of the stand relative to the base and communicates the angular position to the interactive video display. The stand further includes a video display facing in a second direction substantially opposite from the first direction.

Abstract: A method and system that provides for the automatic identification of complementary retail items, based upon a selection of specific characteristics of a consumer's shopping pattern or history, is provided. More particularly, the present invention relates to a method and system that provides for a methodological analysis of selected shopping characteristics in relation to recognition of specific shopping patterns and/or purchased item relationships with customer-specific identified complementary items, and the automated generation and identification of product preferences and purchasing patterns specific to a select consumer. Additionally the present invention is readily used with point of sale (POS) terminals, kiosks and retail-based computer systems.
