DIY Smart Glasses Built with a Raspberry Pi Zero W #piday #wearable #raspberrypi @Raspberry_Pi

DIY Smart Glasses Built with a Raspberry Pi Zero W Hackster Blog

Redditor Infranix built these DIY smart glasses that are reminiscent of Google Glass. Via Hackster.io:

The original Google Glass smart glasses were essentially a small computer mounted to the frame of a pair of glasses. Users could interact with it using a touch pad or voice commands, and information was displayed on a small projection in their field of view. The Google Glass also included a forward-facing camera that could be used to analyze the world or take photos and video — a major factor contributing to the privacy concerns. Infranix’s smart glasses work in a similar way, but omit the camera.

The computer that Infranix used is a Raspberry Pi Zero W single-board computer (SBC) that is mounted to one side of the glasses. On the opposite side, there is a 1200mAh LiPo battery and charging circuit. A small microphone is used to pick up voice commands, which are then processed using a speech-to-text app and used to trigger some action via a Python3 user interface software. The final component is the heads-up display, which Infranix built used a small OLED screen that is reflected off of a piece of transparent plastic so the user can see it.

  1. See, problem with this and Google Glass is they looked ghastly due to the massive asymmetry in the design.
    If the designs were more symmetrical they could not only look much nicer, they could have more functionality embedded inside.

    This does look better in terms of the larger display, but the huge arm coming out, again, looks bad. (IMO)
    I think if you are going to have a huge arm like that, you are better off making it come from the top so as to not block your sideways peripheral vision. Sideways peripheral vision is more important than upwards peripheral vision in almost all daily life unless you live in the wilderness where height comes in to play.
    Preferably, you could center that arm from the top middle of the glasses and have the projection come in from the middle slightly diagonally. You’d need to tilt the screen and maaaybe use a lens to get the orientation proper, but it could work well and look nice. If not, you could try minimize the footprint of the projection circuit and put it right in the middle across from where it was originally, then flip the panel.
    Plus, in that arm you could add circuitry rather than have it clear since it won’t be blocking the useful side peripheral views.
    One thing I would definitely consider doing in a further revision of this is hard-wire the connections so there isn’t huge USB connectors sticking out. Easy enough to do compared to the above since it’s a much more substantial change.

    I like all the various takes people have come up with for AR and smart glasses. With the ever increasing performance and shrinking computers it’s only going to get better.
    When graphene or similar substrate finally arrives to market, hoooo boy it’s going to change the whole wearable computing industry. Can’t wait.
    Finally we might be able to get that AR baseball from Eureka! TV show!
