People who are deaf or cannot speak, or both – have long been aided by the American Sign Language (ASL) in communicating with people. Although the accuracy of the communication solely depends on the understanding of people on both ends, that can be a problem if one or more conversants are not that fluent in ASL. Researchers at Cornell University have recognized this problem and want to leverage the goodness of wearable technologies to make it smoother for people who are differently abled to communicate with the world as they intend to.

The experts at the university have employed the smart ring platform to develop a wearable that tracks the American Sign Language gestures of the wearer to accurately transcribe them into understandable text or audio to a computer or a smartphone. They call it the SpellRing, and it can be worn on the thumb to get the desired input for the translated data. The wearable comes with embedded sensors including a mini-gyroscope to measure the angular data from hand movement. The on-board speakers and mic detect the inaudible sound waves from the movement. All these components are housed inside a 3D-printed housing that’s no more than the size of a quarter.

The smart AI ring can detect all 26 letters in the English language with micro-sonar technology to precisely track the fingerspelling of the wearer. For more accuracy sonar images are also fed into the system. The data that is received from all the sensors and hardware is then processed by a deep-learning algorithm. All of this is done in a split second time to predict the ASL fingerspelled by the wearer. To make possible an in-depth and unbiased view of the wearable for further development, the researchers from Carnegie Mellon University and Stony Brook University, along with the researchers from Cornell University have tested the wearable thoroughly.

In the conducted tests, 20 amateur and experienced ASL signers were asked to spell more than 20,000 words to see the accuracy of the AI-assisted wearable ring. The 3D-printed wearable passed with a combined accuracy of around 90 percent with both signed words, as well as, sentences. It was even tested to perform actions such as web search, map navigation, or typing in notes with the input. According to Hyunchul Lim, lead author of SpellRing’s papered documentation, “ASL is a very complicated, complex visual language,” and the focus is right now on tuning the algorithm to make the AI ring understand words and phrases with maximum accuracy.

The SpellRing is currently in the prototype stage and there is no word on the availability of the ring yet. The team is confident that even in the current stage, ASL fingertyping will be significantly faster than typing on your smartphone’s keyboard. Researchers want this ring to be a tool for fast and accessible text entry with a niche set of benefits targeted toward a set of users. The prospects of this AI ring graduating to the wearable market are very high since it costs just $30 to make the current prototype AI ring. When it will be mass produced that cost can be further trimmed down.

Teenage Engineering-inspired flashlight concept breaks the mold with a boxy design

In the course of using some everyday products, we probably seldom stop to question why things are designed the way they are. Why are appliances like speakers and air purifiers traditionally rectangular and boxy while flashlights and lamps are cylindrical? Sometimes, the answers lie in history and practicality, but other times it’s just a matter of convention and the lack of motivation to think outside the box.

This flashlight design concept, however, isn’t afraid to dare to be different, perhaps even to the point of sacrificing some ergonomics. Embracing a trending design aesthetic, it isn’t just breaking the mold by throwing out most conventions. It is also challenging those conventions to see what’s possible if we’re not afraid to ask “What if?”

Designer: Nikhil Kapoor

Industrial design aesthetics has carried a rather negative connotation of being cold and impersonal, but recent trends have cast a more positive light on modern renditions of the design language. Teenage Engineering’s products, in particular, have presented a certain flavor of minimalism that embraced the cold surface of metal, the angular and sharp edges of boxes, and an intentionally limited color palette.

The FL-1 flashlight concept embraces these design elements to shock and confound. Instead of the conventional barrel form, it comes in a box that will admittedly be cumbersome to hold for long periods of time, at least depending on the size. It could easily fit in the palm of your hand, as many EDC flashlights do these days, but the sharp edges could bite into your skin over time.

The design does have a few interesting features beyond its industrial aesthetic. The rectangular shape gives it enough room to fit two LED lights, which can be turned on individually or together with a simple sliding switch mechanism. There’s also a display to show the remaining battery charge so you’re never caught unaware. The flashlight is charged via USB-C, which is the only reference to the correct scale of the object.

Like Teenage Engineering’s designs, the FL-1 practically uses only two colors, or three if you count the contrasting shade of gray. A vibrant orange backside increases its visibility, but only if it’s upside down, while there’s no method for seeing the flashlight in the dark if it’s right side up. The concept definitely has its flaws, but it is still a worthwhile thought experiment on how we can challenge the status quo and come up with designs that aren’t just different but also even better.

Sarang Sheth

Few moments in fantasy history are as iconic as Gandalf’s showdown with the Balrog on the Bridge of Khazad-dûm. Now, thanks to a collaboration between Drop and The Lord of the Rings, this epic clash has been immortalized in a way that combines fandom with functionality. The Balrog and Mithrandir Artisan Keycap and Spacebar set offers a chance to bring the magic of Middle-earth to your fingertips, and it’s more than just a collector’s item. It’s a fusion of premium craftsmanship, stunning design, and technical precision that adds a touch of the fantastical to your everyday typing experience.

Designer: Dwarf Factory for Drop

Crafted by Dwarf Factory, each piece is an artisan masterpiece in resin, featuring rich details that evoke the essence of these legendary characters. The Balrog, with its fiery menace and aggressive stance, looks ready to engulf your entire keyboard, while Mithrandir stands resolute, channeling his defiant power just as he did when facing the beast. The level of detail is extraordinary—from the flame-like textures on the Balrog to the serene yet powerful expression of Gandalf, these keycaps are tiny works of art. Available in a 1u size for both characters, and with the Balrog also available as a 6.25u spacebar, these keycaps not only add visual impact but are also fully functional. They integrate smoothly with Cherry MX switches and clones, making them a natural fit for most mechanical keyboards.

The 1u Balrog keycap is nothing short of a fiery masterpiece. Designed to reflect the raw power and menacing presence of Durin’s Bane, it features intricate detailing that brings the dark, fiery creature to life. With its flame-engulfed body and haunting expression, the keycap feels like it’s radiating heat right off your keyboard. The resin material used for the keycap captures the vivid colors of fire, from the burning red to deep molten black, creating a striking visual contrast that mirrors the Balrog’s destructive force. Every angle of this 1u keycap has been meticulously designed to showcase the Balrog’s fearsome nature, making it a perfect choice for those looking to add an element of danger and mystery to their keyboard setup. It fits comfortably on any Cherry MX switch or clone, ensuring that it’s as functional as it is eye-catching.

Mithrandir, or Gandalf, takes center stage in the second 1u keycap, offering a calm but powerful contrast to the Balrog. In this design, Gandalf is depicted in his role as the Grey Pilgrim, holding his staff and ready to face down the ancient evil with the iconic line, “You shall not pass!” The keycap perfectly captures the quiet strength and wisdom that defines the wizard, with intricate detailing in his robes and an expression of calm determination. Crafted in resin, the Mithrandir keycap offers a more subtle aesthetic compared to the fiery Balrog, but its craftsmanship is no less impressive. The muted grey tones and flowing details create a sense of movement, almost as if Gandalf himself is preparing to strike. This keycap serves as a symbol of resilience and courage, and for fans of The Lord of the Rings, it’s a meaningful reminder of Gandalf’s pivotal role in the story.

The pièce de résistance, however, is the 6.25u Balrog spacebar. A true showstopper, this spacebar turns your keyboard into a battleground between the Maiar. Unlike the 1u keycap, the spacebar offers a wider canvas, allowing for even more detail in the Balrog’s fiery design. The flames stretch across the length of the spacebar, creating a dramatic scene that feels like it’s pulled straight from the depths of Moria that comes to life with the backlight switched on. The spacebar also features subtle texturing that mimics the rugged look of stone, further emphasizing the destructive force of the Balrog. With its large profile and vivid design, this spacebar commands attention and becomes the focal point of any keyboard. And, like the other keycaps in the set, it’s compatible with Cherry MX switches, ensuring that your epic setup doesn’t sacrifice functionality for style.

The custom-made keycaps are the perfect combination of nostalgia and utility, seamlessly blending a piece of Tolkien’s world into your everyday life. Whether you’re aligning yourself with the fiery might of the Balrog or the steadfast courage of Mithrandir, these keycaps turn your keyboard into a mini piece of Middle-earth. And with their high-quality resin construction, you can trust that they’re built to last, no matter how epic your typing battles become.

Priced at $49, a notable drop from its original $65, the Balrog and Mithrandir Artisan Keycap and Spacebar set is available for pre-order now, with an estimated shipping date of February 10, 2025.
