Similar to Google Glasses, the Raspberry Eye takes advantage of Raspberry-compatible LCDs to attach your favourite pocket-sized computer to your head. Literally. Compared to your average pair of Google Glasses the Raspberry Eye is considerably cheaper costing around $100 compared to the standard $1500 Google Glasses. As a DIY project the Raspberry Eye revolves around the Raspberry Pi- meaning that all the scripts can be written using python. An advantage of this is that you can customise your Raspberry Eye as much as you want, letting you upload your own programs to make full use of this portable ‘head camera’.
