Approaches are described for controlling and filtering the display of content by computing devices. In particular, a mobile computing device can adjust the playing of media content (e.g., audio, video, images, games, ringtones) according to situational appropriateness and other environmental factors occurring around the device. For example, a mobile computing device such as a smart phone could use image and audio information captured by its sensors to determine that minors are present within the vicinity of the mobile phone, and filter certain portions of media content that would be deemed inappropriate for those minors. The environmental information can be determined based on data gathered by various sensors of the mobile device, including but not limited to cameras, microphones, global positioning system (GPS) devices, light sensors and others.
