LG Electronics has unveiled a fitness wristband to monitor the user's heartbeat, calorie consumption and movement, as well as incoming phone calls and music controls.
The Lifeband Touch measures performance via fitness apps and a touch screen.
It can also be combined with earphones that measure blood flow signals from the inner part of the ear to monitor heart rate and oxygen consumption.
Film director Michael Bay walked out of a major product launch on the first day of the Consumer Electronics Show in Las Vegas after appearing to be lost for words.
The director of the Transformers films and Pearl Harbour was speaking at the launch of Samsung's new curved TV when he stopped abruptly, saying: "The type is all off, sorry. I'll just wing this".
A Samsung executive then prompted him to ad lib with some questions, but the director apologised and walked off stage.
Michael Bay later explained on his website that he "got so excited to talk" that he skipped a line, causing the autocue to "get lost".
"I guess live shows aren't my thing," he added.
