In one embodiment, a method executed by at least one processor includes receiving first historical location information identifying a first location area at which a first user was present at a first time and receiving second location information identifying a second location area at which a second user was present at a second time. The method includes determining that the first historical location information and the second location information each correspond to a particular location area and determining that a characteristic related to the first user corresponds to a preference related to the second user. In response to these determinations, the method includes causing information related to the first user to be presented to the second user. The information related to the first user includes the first location area of the first user relative to the second location area of the second user.

An information service provides search and notifications to inform when certain people (e.g., friends, family, business contacts, etc.) are nearby so as to facilitate communications with those people. Users may define lists of people whose locations may be tracked by positioning equipment based on personal communications/computing devices carried by the people. The information service processes this people and place data to identify those of the listed people that are in the user's vicinity, and provide notifications and user-initiated search results informing the user such as via the user's personal communications/computing device.

Users may control visual cues reflective of the user's social intentions and/or state of perception during use of personal electronic devices. In some embodiments, the visual cues may be provided by visual indicators on headphones, such as a multi-color LED, which change status based on the user's desired interactions with others. An LED embedded within an earphone may, for example, glow red when a user prefers not to be interrupted or when a user's device inhibits perception of external sounds, or glow green when a user is open to and available for interaction with others. The visual indicator status may be controlled manually by a user, or automatically. Visual cues may implement multiple discrete states, or may vary along a continuum of color and/or illumination level. A cloud server may track a user's visual cue state, for use in controlling or otherwise interacting with other network-connected services.
