The glasses can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glasses using your voice, and a touchpad on the right arm of the frame.

　　Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glasses. “I thought this is something I definitely need for my classroom and hopefully for my personal life too. ”

　　The Professor’s Google Glasses look like a pair of bright orange glasses, without the actual glass. But there’s a tiny rectangular glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class.

　　But not everyone is excited about Google Glasses. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog. “It is essentially going to allow people to come in and spy on you and record that, without you knowing what is going on. ”

　　Google says that it has already addressed that concern. Mr Dale explained that in order to start the camera or record a video, the owner must say something out loud. “I activate the device, and say ‘Okay, glass, take a picture. ’Similarly, I have to push a little button on the top here so everybody around me will know a picture is being taken and a video is being recorded. ”
