Intelligent Adjustment of Phone Behavior

From PDI

Mobile phones should be able to dynamically adjust their ringer volume and other behavior based the environment and context. For example:

• Before ringing, a phone could use its microphone to sample ambient noise in order to know how loudly to ring. If you're in a restaurant, it will ring loudly so that you can hear it over the noise, but if you're working quietly in your office, it can ring softly.
• A user should be able to configure the type of ring for different contexts. For instance, a soft tone for when it's quiet, or a loud alarm for when it's noisy.
• Phones could use heat sensors to determine if they are in your pocket, and only vibrate rather than ring. If it determines that it's not in your pocket, it shouldn't bother vibrating, and should only use an audible tone.

Users could customize all kinds of behavior based on environmental contexts like ambient light, ambient noise, heat signature, proximity to the face, etc.
