Sony's Bravia WE5: scans for viewer movement

The electronics giant recently launched the 100Hz Bravia WE5 “Eco” TV, which is fitted with a motion-sensor that tells the set to switch its display off if you’ve fallen asleep during yet another late night film, or have stepped into the kitchen to make some cheesy burritos.

But Christian Brown, Sony UK’s Senior Product Manager for TVs, this week hinted to Register Hardware that the feature – officially called Presence Sensor – could soon become a standard feature on more of its tellies.

“I would hope it [Presence Sensor] will become a standard feature, otherwise it wouldn’t have been put on there,” he said.

Presence Sensor could become a standard feature on larger sets

Although Presence Sensor doesn’t turn down the sound or put a blanket over you, Sony claimed that the feature cuts the WE5’s power consumption by approximately 50 per cent.

It’s worth noting that Sony’s not the only TV manufacturer adding power-saving features to TVs. The backlight built into Philips’ Eco Flat TVs can be dimmed to help reduce the sets' overall power draw. And late last year Sharp demoed a 52in solar-powered set. ®
