The wearable device tracks the user's eye movements and pupil position to move a mouse cursor around on a device.
People who cannot use their hands with full efficiency may find it extremely difficult to interact with touchscreen devices. So as to determine where you are looking, one of the IR CSI cameras feeds a continuous video stream to the Raspberry Pi Compute Module 3+ running OpenCV (which is a library focused on real-time-computer-vision).
New research suggests that graphene—made in a specific way- could be used to make more durable hydrogen fuel cells for cars. In the study, published in the journal Nanoscale, scientists produced graphene via a special, scalable technique and used it to develop hydrogen fuel cell catalysts.
