Claim Text:
1. An apparatus comprising: a controller; a first part comprising at least a first proximity sensor; a second part comprising at least a second proximity sensor; a third part comprising at least a third proximity sensor on one face of the third part and a fourth proximity sensor on an opposing face of the third part; an arrangement configured to add the third part between the first part on a first stack and the second part on a second stack to change a configuration of the apparatus between a first configuration in which the first part and the second part are adjacent and exposed side-by-side on top of the different first and second stacks and there is no third part between the first part and the second part, and a second configuration in which the first part and the second part are separated by the third part, the first and second parts are no longer adjacent, and the third part is adjacent to the first part and is adjacent to the second part, wherein the controller is configured to pair the first part and the second part, not the third part, as a user interface when the apparatus is in the first configuration, and is configured to pair the first part and the third part, not the second part, as a user interface when the apparatus is in the second configuration and the first part and the third part are exposed side-by-side on top of the different first and second stacks, and is configured to pair the second part and the third part, not the first part, as a user interface when the apparatus is in the second configuration and the second part and the third part are exposed side-by-side on top of the different first and second stacks, wherein the apparatus is configured to identify whether the apparatus is in the first configuration or the second configuration and whether the first part and the third part are exposed side-by-side on top of the respective first stack and second stack or whether the second part and the third part are exposed side-by-side on top of the respective second stack and first stack by detecting communication between the first proximity sensor and the third proximity sensor but not between the fourth proximity sensor and the second proximity sensor to determine that the third part and the second part are exposed side-by-side on top of the respective first and second stacks, and by detecting communication between the second proximity sensor and the fourth proximity sensor but not between the third sensor and the first sensor to determine that the first part and the third part are exposed side-by-side on top of the respective first and second stacks.
