Sony today announced SmartEyeglass, the company's take on Google's recently shelved Glass project. The device interacts with the surroundings in similar ways, connecting with compatible smartphones to render text, symbols and images into the wearer's field of view. Developer pre-orders have actually kicked off for the Sony SED-E1 SmartEyeglass, which will set you back $840 before tax. Units will be available in Japan, Germany, the UK and US from March 10.
