Sociology of cellular

"The Effects of Mobile Telephones on Social and Individual Life" is an interesting paper by Motorola sociologist Dr. Sadie Plant. Joi points out the fascinating stuff on cellular body-language:
Those who use their mobiles with this light touch often have their index finger aligned with the aerial at the top of the phone. There are also variations in the ways in which people’s eyes respond to a mobile call. Some mobile users adopt the scan, in which the eyes tend to be lively, darting around, perhaps making fleeting contact with people in the vicinity, as though they were searching for the absent face of the person to whom the call is made. With the gaze, the eyes tend to focus on a single point, or else to gaze into the distance, as though in an effort to conjure the presence of the disembodied voice.
