Detector Devices for Presenting Notifications and Supporting Context Inferences

Techniques can relate to a multi-purpose a detector surface on a network device. A stimulus variable can be identified at a detector device based on an environmental stimulus detected by a sensor. The detector device can include the sensor. The detector device can transmit an initial communication to a device. The first communication can include the stimulus variable. A new communication that includes data corresponding to another device can be received at the detector device. The detector device can determine, based on the stimulus detected by the sensor and is further based on the new communication, that a visual stimulus is to be presented. The visual stimulus can be presented.
