Japanese researchers have developed a strange new device that will sense the mood of the individuals in a room. Called a "Symbiotic Hosting Online Jog Instrument", or SHOJI for short, the device transmits a colored light whose hue and brightness vary according to temperature, movement, humidity, infrared radiation, ultrasonic vibrations and other factors that may be affected by the human beings in its vicinity. Its inventors intend to market the device to corporations wishing to monitor the emotions of their employees, and it sells for about $3,000 a unit. What will they think of next? Lie detectors in conference rooms?
