Abstract: An optical wireless communication device comprises: at least one of a transmitter and a receiver configured to transmit and/or receive light comprising an optical wireless communication signal representing data; at least one adjustable shutter element associated with the at least one of a transmitter and a receiver, wherein the at least one adjustable shutter element and the associated at least one of the transmitter and the receiver are adjustable between a first configuration and a second configuration such that in the first configuration the at least one adjustable shutter element is configured to at least partially block or partially redirect light having a first selected property and at least partially allow light having a second selected property to pass through unaffected such that transmission and/or reception of the optical wireless communication signal by the at least one of the transmitter and the receiver is substantially altered.

Abstract: A computing device is operable to work in conjunction with a companion electronic device. The computing device and the companion electronic device each have their own electronics and/or own operating system and each is able to construct a partial or complete user environment. The computing device is operable to send data to the companion device, on request of the companion device, which the companion electronic device then uses to locally construct its own user environment, in whole or in part.
