The idea of a “contact lens display” concept might one day become the ultimate way to implement augmented reality (AR), but it’s a highly challenging endeavor. MojoVision is one of the companies working to make this happen and its CEO has done it demonstrated a Mojo Lens prototype placed on his eye.
The Mojo lens is a contact lens with all the electronics to: a 0.5mm display with extremely small 1.8 micron pixels. The small size of the display currently limits the effective image resolution, but this could be improved later.
The content of the display is visible even in bright daylight and even with closed eyes.
The lens communicates with a computer via a 5GHz radio, and so data flows back and forth, including the image data. Mojo Vision says the communication is low-latency, but it’s unclear how responsive it is.
Eye movements are tracked using an accelerometer to stabilize the image in the user’s field of view. This motion data allows the computer to compensate for eye movement when updating the rendered image.
Mojo Vision uses the person’s gaze as a control, and commands can be given by looking and perhaps staying on the target for a short time. Many AR applications already have similar interfaces with XR (eXtended Reality) headsets.
It is a milestone to build such a contact lens completely wireless. The company says Mojo Lens is powered by “medical grade micro batteries.”
while it is a science fiction level of technological achievement, one has to wonder how the image quality is, how wide the field of view is and what the cases are. At a high level it would be great to have a high resolution display as it would be so helpful in all sorts of XR applications.
On the other hand, many people are reluctant to have anything on their eye, especially when it comes to electronics and a battery. I suspect that even if it worked perfectly today, it would take many years and killer application before it became mainstream.
