State-of-the-art sensors that can measure stress levels, mood, posture, performance and even smell took centrestage at Asia's top high-tech fair in Tokyo.
The big-screen TVs and entertainment systems that were all the rage 10 years ago at the CEATEC fair have gradually been replaced by tiny sensors that accurately measure the minutest facet of the human body - a Japanese speciality.
Electronics giant Panasonic showcased a prototype of an armchair that measures how much the user's hands sweat along with the seating position and facial expressions via a camera, all to determine stress levels.
This could be useful for an airline pilot or long-distance truck driver, for example, but could also one day find its way into the workplace.
"You could imagine such a chair in the office and by combining the results with air conditioning and lighting levels, you could adjust the ambiance of the office to enable people to relax if necessary," a Panasonic demonstrator said.
Components manufacturer Murata Manufacturing has pioneered a small device that is held for a minute between the thumb and forefinger to measure pulse rates and the nervous system.
"We are going to start selling this very soon to companies, so they can measure how stressed their employees are. Transport and taxi companies are especially interested," said Takashi Hayashida, a spokesman for the firm.
Staff equipped with sensors could be under permanent surveillance to "improve their posture and productivity," according to Japanese electronics firm TDK.
This also extends to the field of play, with Fujitsu demonstrating a 3D analytical system based on sensors to improve the performance of gymnasts.
Sensors are also being put to work to improve healthcare - especially for the elderly, with nearly 28 per cent of the Japanese population over 65.
