Abstract: Devices and methods are disclosed for a user interface permitting interaction directly between a user and devices of a device environment. A user interface device includes a display screen and memory storing representations of devices, their functions, and interaction rules. A processor displays the representations of devices and functions with connections shown between the representations on the screen to visually present the interaction rules. Choices may be provided through a user interface for user initiated learning in the environment so the user may initiate state changes on the devices themselves to produce the interaction rule. Additionally, the user may create a rule by selecting representations of devices and their functions on the screen to associate a function of one device with a function of another device. Also, a choice of device to query for information may be displayed on the screen, and the queried information is displayed once received.

Abstract: Devices and methods are disclosed for controlling content within a device environment through interaction among electronic devices of the environment. The device has a transmitter, receiver, memory storing interaction rules and content rules and a processor for implementing the interaction rules and content rules in association with the transmitter, receiver, and other devices of the environment. Methods involve obtaining content information of the media about to be played and comparing the content information to the content rules stored at a device. An instruction about playback of the media content is generated. Methods may also involve seeking rights information for media content and determining whether rights information exists for identified media content in response to the request. When rights information does exist for the identified media content, a message is sent that includes the rights information.

Abstract: Devices and methods are disclosed for establishing device interaction among electronic devices of an environment. The device has a transmitter, receiver, memory storing interaction rules and a processor for implementing the interaction rules in association with the transmitter, receiver, and other devices of the environment. The device also includes components for performing the device specific functions and a state sensor for determining the logical or physical state of the device. The methods involve detecting a change of state at a device and then communicating in accordance with the interaction rules thereafter. The communication may involve broadcasting change of state messages to the environment, directing change of state messages to specific devices, and directing requests and/or directing replies to requests. Through device interaction, changes of state may automatically occur at one device in response to a change of state at another in order to reduce the burden on the user.
