[…]Dr. Prabhakar clearly set up the DARPA’s latest incarnation as a return to the big vision, swing for the fences approach. She discussed DARPA’s approach to managing risks while creating high impact technologies. In this vision, DARPA’s role is to help scientists and innovators to “remove early risk” which might prevent them from obtaining investment and bringing novel ideas to market. DARPA was described by one presenter as a “always friendly, but somewhat crazy rich uncle” and they made it clear that they were going to put a fair bit of money behind these ideas.
This meeting was focused around the launch of the new program office, the Biotechnology Program Office, although other program managers were present. The BTO is headed Dr. Geoff Ling who is a practicing Army medical doctor. Dr. Ling is an energetic spokesman for the DARPA vision and the BTO. And it is notable that it is an M.D. that is in charge of this effort because many of the developments being undertaken by the BTO are simply going to revolutionize the practice of medicine as we know it today. With the energetic Dr. Ling in charge, you can imagine it getting done. […]
The first Program Manager to present, Phillip Alvelda, opened the event with his mind blowing project to develop a working “cortical modem”. What is a cortical modem you ask? Quite simply it is a direct neural interface that will allow for the visual display of information without the use of glasses or goggles. I was largely at this event to learn about this project and I wasn’t disappointed.
Leveraging the work of Karl Deisseroth in the area of optogenetics, the cortical modem project aims to build a low cost neural interface based display device. The short term goal of the project is the development of a device about the size of two stacked nickels with a cost of goods on the order of $10 which would enable a simple visual display via a direct interface to the visual cortex with the visual fidelity of something like an early LED digital clock.
The implications of this project are astounding.
Consider a more advanced version of the device capable of high fidelity visual display. First, this technology could be used to restore sensory function to individuals who simply can’t be treated with current approaches. Second, the device could replace all virtual reality and augmented reality displays. Bypassing the visual sensory system entirely, a cortical modem can directly display into the visual cortex enabling a sort of virtual overlay on the real world. Moreover, the optogenetics approach allows both reading and writing of information. So we can imagine at least a device in which virtual objects appear well integrated into our perceived world. Beyond this, a working cortical modem would enable electronic telepathy and telekinesis. The cortical modem is a real world version of the science fiction neural interfaces envisioned by writers such as William Gibson and more recently Ramez Naam.
