The same company has also invented a sensor which can be placed in luggage to reveal whether suitcases get bashed around by handlers during flights -- and reveal a suitcase's location should it get lost in transit.
Furukawa said the sensor was a prototype that they hoped could be commercialized by a luggage manufacturer.
Electronics giant Panasonic also displayed their vision of what a hi-tech home could look like, complete with a variety of gadgets and appliances that communicate with each other.
That includes a mirror which, when hooked up to the rest of the gadgets in the home, can display your body mass index (BMI) -- a measure of body fat based on height and weight -- when a user sits down in front of it.
The mirror can also gauge how healthy your skin is as well as overlay virtual cosmetics on a user's face to help guide their morning make-up routine after a regret-tinged night on the tiles.
The same home also boasted a dining room table and window which can react to conversations -- displaying, for example, images of a recent trip a family might have taken once they start talking about it.
Company spokesman Daisuke Uehara said their presentation was an idea of what a home might look like in 2018-20.
"There are no concrete commercialization plans but we already have this technology to realise if customers wanted it," he said.
About 530 companies are taking part in the trade show, around one quarter foreign exhibitors from 19 countries and regions, led by China, Taiwan and the United States.
