Watch out: Wearable projects time, emails and Twitter notifications onto your hand

A new take on the wristwatch presents a sleek way to not only tell time, but view notifications from your smartphone as well — all on the canvas of your skin.

The watch, called Ritot, safely projects its messages onto your hand instead of using a screen or a typical watch face.

Simply shake your hand or press the button on the watch and the time appears on your skin. Sync it with the Ritot phone app to receive caller ID and text messages, emails, Facebook messages, Twitter alerts and notifications from any other apps you’d like.

Unlike some other wearable technology devices, which can be bulky and indiscreet, Ritot has attempted a simpler approach.

In terms of design, the waterproof band is made of aluminium with a leather finish that resembles a stylish accessory rather than a bulky piece of tech gear. It comes in black or white, but wearers can choose between more than 20 colours for the projections.

Ritot also differs from other smartphone notification wearables in that it can actually show you the message you receive, instead of simply vibrating to let you know that you should take out your phone.

A sport version of the watch made of rubber and plastic is also available. This style could be useful during runs or exercise sessions because of its large, projected interface, making it easy to read your mileage and calories burned just by looking at your hand.

The technology behind Ritot is a tiny pico projector encased within the bracelet that is activated through a touch sensitive button. The high quality of the projections makes notifications readable during the day or night and in any weather.


Projecting the time or short messages onto your hand could be useful in on-the-go situations where it would be inappropriate to pull out your phone. Perhaps further developments to this technology could take Ritot beyond projections of simple messages to providing more detailed projections of actual screens.

Each Ritot watch comes with a base that enables the wearer to change the colours of its projections, charge the watch wirelessly and change the display mode. In a less high-tech but nonetheless useful feature, the base also doubles as an alarm clock.

The San Jose, California-based startup behind Ritot has recently launched an Indiegogo campaign to fund the development of the product, hoping to mass produce and distribute the watches by early next year.

Steve “Woz” Wozniak to advise hologram emoji company that he calls “groundbreaking”

Apple’s co-founder Steve “Woz” Wozniak has found himself a new gig; Woz has joined the hologram emoji company, Mojiit, as an adviser.

In his role as advisor to Mojiit, the legendary entrepreneur and engineer will help assemble a world-class engineering team in addition to bringing investors and partnerships to the newly launched startup. Wozniak will also serve as mentor to Mojiit founder, Jeremy Greene.

“I’m thrilled to join Mojiit as an advisor,” said Wozniak. “Jeremy is a natural leader, the company is groundbreaking, it’s going to change the ecommerce space, and it’s a lot of fun.”

Created in 2017, Mojiit is the latest startup technology venture from Greene. The company’s tech essentially enables users to project and share 3D hologram emojis via smartphones.

The platform turns users into emojis by scanning their face, which can then be sent to loved ones and friends. Once a Mojiit message is received, it will map the area where it is received and place the Mojiit hologram there in real time, so it works in a similar way to Pokemon Go.

“Steve is one of the best and brilliant engineers in the entire world. But outside of that, he’s a wonderful man,” said Greene. “There isn’t anyone I’d want to be in business with more than this guy. He’s a legend. Who better to learn from than the guy who created the computer?”

In addition to consumer use, businesses of all kinds can tap into hologram emojis with Mojiit’s technology.

Mojiit investors already  include NFL alum Ed Reed, and the company was able to raise a total of $1 million in its seed round of funding.

Alongside the appointment of Woz, Entourage and Ballers producer Rob Weiss recently joined the company as a creative director.

“It’s exciting to expand beyond television and film to digital platforms,” said Weiss. “Hologram technology brings incredible opportunity to entertainment and media. I’m thrilled to be leading creative at Mojiit.”

Nanoengineers send antibiotic-delivering micromotors into the body to treat cancer-causing infection

Nanoengineers have demonstrated for the first time how “micromotors” that measure half the width of a human hair can be used to transport antibiotics through the body.

Nanoengineers at the University of California San Diego tested the micromotors in mice with Helicobacter pylori infections, which can also be found in about two-thirds of the world’s population and while many people will never notice any signs of its presence it can cause peptic ulcers and stomach cancer.

The mice received the micromotors – packed with a clinical dose of the antibiotic clarithromycin – orally once a day for five consecutive days.

Afterwards, nanoengineers evaluated the bacterial count in each mouse stomach and found that treatment with the micromotors was slightly more effective than when the same dose of antibiotic was given in combination with proton pump inhibitors, which also suppress gastric acid production.

Micromotors administered to the mice swam rapidly throughout the stomach while neutralising gastric acid, which can be destructive to orally administered drugs such as antibiotics and protein-based pharmaceuticals.

Because gastric acid is so destructive to traditional antibiotics drugs used to treat bacterial infections, ulcers and other diseases in the stomach are normally taken with additional substances, called proton pump inhibitors.

But when taken over longer periods or in high doses, proton pump inhibitors can cause adverse side effects including headaches, diarrhea and fatigue. In more serious cases, they can cause anxiety or depression.

The micromotors, however, have a built-in mechanism that neutralises gastric acid and effectively deliver their drug payloads in the stomach without requiring the use of proton pump inhibitors.

“It’s a one-step treatment with these micromotors, combining acid neutralisation with therapeutic action,” said Berta Esteban-Fernández de Ávila, a postdoctoral scholar in Wang’s research group at UC San Diego and a co-first author of the paper.

The nanoengineers say that while the present results are promising, this work is still at an early stage.

To test their work, the team is planning future studies to into the therapeutic performance of the micromotors in animals and humans, and will compare it with other standard therapies used to combat stomach diseases.

UC San Diego nanoengineers also plan to test different drug combinations with the micromotors to treat multiple diseases in the stomach or in different sections of the gastrointestinal tract.

Overall, the researchers say that this work opens the door to the use of synthetic motors as active delivery platforms in the treatment of diseases.
