"Parviz: We have a pretty powerful processor and a lot of memory in the device. There’s quite a bit of storage on board, so you can store images and video on board, or you can just live stream it out. We have a see-through display, so it shows images and video if you like, and it’s all self-contained. It has a camera that can collect photographs or video. It has a touchpad so it can interact with the system, and it has gyroscope, accelerometers, and compasses for making the system aware in terms of location and direction. It has microphones for collecting sound, it has a small speaker for getting sound back to the person who’s wearing it, and it has Wi-Fi and Bluetooth. And GPS.
