The app is free. A subscription opens every lesson, in every school year.
In the picture
- Glasses camera: captures the scene in front of the wearer.
- Belt pack processor: converts camera images into electrical signals.
- Wireless link: carries signals from the processor to the implant.
- Retina electrode array: stimulates retinal cells to send visual signals.
Examples
- A phone sending a photo to a printer over Wi-Fi.
- A cochlear implant turning sound into electrical pulses.
Key takeaways
- The camera and processor are outside the body; the electrode array is inside the eye.
- The wireless link connects the external processor to the implanted array.
