Abstract: Described is a technology by which mobile telephones are organized and/or operate based upon special relationships with other users and/or other mobile telephones. A mobile computing device is coupled to another mobile computing device so as to have a special relationship therewith, including after subsequent decoupling. When the mobile telephones that have a special relationship are thereafter coupled together, the devices may operate differently (relative to their operation when coupled to other mobile telephones). Also described is a single user interface screen that outputs an identifier (e.g., an image) of a potential recipient, along with communication options, such as to call, send a text message, share data, show information or send a predefined message.

Abstract: Described is a technology by which a mobile telephone sends and/or receives and outputs a “mobile hug” comprising a personalized special message. A mobile hug output comprises vibration rhythms (patterns) and/or other sound and/or image data that identifies a source of the incoming information, and/or may convey a personal message. A mobile hug protocol is exemplified in which a vibration timeline, a sound timeline, and/or an image timeline each comprising units from which a sender can assemble a “sentence” to convey the special message.
