In our times mobile phones are nearly ubiquitous. We rarely (if ever) rely on standard phones, and we use phones in the most unexpected situations/places. While this advantage of mobile devices doesn't usually have any negative impact on our private conversations, it can affect business/official phone calls. It's quite common to hear dogs' barking, street noise, kids screaming during important teleconferences. It seems that some people are not aware how sensitive a standard microphone can be, and keep forgetting about switching to mute when not conversing.
In this publication we suggest a method for dynamic activation of microphone/loudspeaker based on a phone's orientation and proximity sensor's readings. The idea of this publication is to present a user with an option of switching to teleconference mode (this basically means that user is expecting that he will not actively take part in the conversation during its entire duration). When in the teleconference mode, the phone's operating system identifies situation when the phone is not being held closely to one's face and is lying horizontally on some surface - this should enable listen only mode. The listen only mode disables microphone and enables loudspeaker (unless headphones are plugged in). When the phone is being picked up and held vertically close to one's face, loudspeaker is disabled and microphone switches on. When the phone is in horizontal orientation but still in user's hands (it could be detected using thermometer, altimeter or light sensor) loudspeaker should also be disabled, but the phone should remain in mute mode.
Almost all smart phones nowadays have sensors like accelerometer and gyroscope. Those two senors are sufficient to define in which position smart phone is held (vertical, horizontal - from gyroscope) and if it has been moved (any direction - from accelerometer).
