Virtual Reality Contact Lenses Are One Step Closer to Reality
As Dr. Michio Kaku has been predicting for years, we are inching ever closer to producing virtual reality contact lenses that will add a layer of interactive, rich information over our mundane visual landscape.
The newest innovation comes from a joint venture between DARPA (Defense Advanced Research Projects Agency) and a technology company called Innovega.
Innovega describes the new technology and its potential applications thusly:
Innovega designers and partners considered the future of personal media, social networking, and mobile computing, and converged upon an aggressive design-point that meets today’s needs as well as demands of high-performance AR which require a see-through and panoramic display interface. Innovega refers to its innovative product as a ‘lifestyle interface‘, since consumers view their digital content in a way that is similar to how they see the world around them. By providing a transparent, fashionable, and comfortable interface that is consistent with today’s active lifestyles, the architecture also eliminates the social barrier that traditional opaque and bulky video eyewear seems to create.
Now, before you rush and order your own Innovega iOptik set-up, there are a few caveats. For one thing, you won’t be able to just insert a contact lens and start living in your own personal version of Minority Report. The new contact lenses are only half of the equation; you also have to wear a set of proprietary glasses that work in conjunction with the lenses to produce the promised futuristic effect. The lenses themselves act primarily as dynamic focusing tools, using nano-fabricated elements to make the optics of the “augmented reality” glasses work correctly. If Innovega follows through on this promise, iOptik users will have access to a quasi-virtual “screen size that is equivalent to a 240 inch television (viewed at a usual distance of 10 feet).”
While the lack of a self-contained contact lens that can act as a virtual overlay on your vision might seem a tad disappointing, the new Innovega technology is a big step toward realizing that dream. In the past, virtual reality or augmented reality technology has required either giant helmets, bulky headsets with various accessories, or complex systems of cameras and projectors. Innovega has shrunk this down to a pair of glasses and contact lens. Can full, in-eye virtual reality be far off?
Ever since we've had the technology, we've looked to the stars in search of alien life. It's assumed that we're looking because we want to find other life in the universe, but what if we're looking to make sure there isn't any?
Here's an equation, and a rather distressing one at that: N = R* × fP × ne × f1 × fi × fc × L. It's the Drake equation, and it describes the number of alien civilizations in our galaxy with whom we might be able to communicate. Its terms correspond to values such as the fraction of stars with planets, the fraction of planets on which life could emerge, the fraction of planets that can support intelligent life, and so on. Using conservative estimates, the minimum result of this equation is 20. There ought to be 20 intelligent alien civilizations in the Milky Way that we can contact and who can contact us. But there aren't any.
Building a personal connection with students can counteract some negative side effects of remote learning.
- Not being able to engage with students in-person due to the pandemic has presented several new challenges for educators, both technical and social. Digital tools have changed the way we all think about learning, but George Couros argues that more needs to be done to make up for what has been lost during "emergency remote teaching."
- One interesting way he has seen to bridge that gap and strengthen teacher-student and student-student relationships is through an event called Identity Day. Giving students the opportunity to share something they are passionate about makes them feel more connected and gets them involved in their education.
- "My hope is that we take these skills and these abilities we're developing through this process and we actually become so much better for our kids when we get back to our face-to-face setting," Couros says. He adds that while no one can predict the future, we can all do our part to adapt to it.
Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.
