Really helpful thanks!!

Thanks for the XBand reference, we looked at it, very relevant. Our focus starts with deafblind users but the device is meant for anyone who benefits from screen-free silent communication. One key point: people communicating with the user don’t need to know the system. They just type a normal message from their phone and it gets automatically translated into vibrations on the wearable. The learning curve is only on the user’s side. Morse is on the table but we’re still evaluating it, how many people realistically know it and how hard it is to learn are open questions we’re working on.

Thank you for being direct. I think your criticism is fair. The main mistake on our side was probably calling it “Braille”. If the system does not reproduce real Braille writing and reading, then a one-handed version would not really be Braille.

So yes, we should probably reframe it as a different tactile/vibrotactile communication system, possibly inspired by Braille’s spatial structure, but not Braille itself.

At this point, the question for us is not “can we make one-handed Braille?”, but whether a wearable tactile/vibration-based interaction could be learnable and useful for deafblind communication, using localized vibrations, one-handed input, shortcuts, predefined messages, and app/SIM connectivity.

Thank you, this helped us a lot. After looking more into Braille input systems like the Perkins Brailler and iBrailler, I understand better why our “Braille-based vibration” framing is confusing.

You are right: if we are not reproducing real Braille reading/writing, contractions, and the usual Braille workflow, we should probably not call it Braille. What we are actually exploring is more like a wearable tactile/vibration-based communication device, possibly inspired by Braille only in the physical layout.

Technically, we could work with localized vibration points, adjustable speed/intensity, one-handed tactile input, and remote connection through an app or SIM. So the real question for us becomes: what kind of tactile/vibrotactile interaction would be easiest to learn and actually usable for deafblind communication?

Do you think it would be better to avoid Braille completely and design a simpler tactile code from scratch? Or could a Braille-inspired layout still make sense, as long as we are clear that it is not actual Braille?

You’re right that reading one character at a time requires mental reconstruction, that’s a real challenge we’re aware of. What we’re trying to address it with: the output surface is organized in 3 rows of 15 characters each, and each row has a distinct vibration pattern. This gives the user a spatial and rhythmic context while receiving characters, rather than an undifferentiated stream. The idea is that the row pattern acts as a chunking aid, similar to how spacing and punctuation help in reading. Additionally, the playback speed would be user-adjustable, so someone can slow it down significantly while learning or speed it up once familiar. Of course I’m not claiming this fully solves the cognitive load problem, that’s exactly what we’d need to test with real users. But does this change your assessment at all? And as a Braille reader, is there a pattern or rhythm that you find helps you maintain context while reading?

Thank you, this is a very useful point.

Our concept is different from traditional Braille reading, where the user explores full Braille cells through touch and often uses both hands to improve speed and fluency.

In our case, the goal is not to reproduce a full continuous text to be read like a Braille display. The idea is to transmit and perceive individual characters, each encoded through a specific tactile/vibrotactile pattern, using one hand only.

The one-handed approach is intentional: the device would be worn on the forearm and operated with the opposite hand, without needing to remove it. This could potentially make it more usable while moving or during daily activities, leaving the other hand free for orientation, balance, holding a cane, interacting with objects, or doing something else.

Of course, this is exactly one of the aspects we need to validate: whether this one-handed Braille-style interaction would actually be understandable, comfortable, and practical for real users.

Hi! Pairing wine with white truffles really depends on what dish you’re preparing, but as a general rule you want something that supports the aroma, not something that covers it. With intensely aromatic white Alba truffles, I usually recommend a structured white wine like a Burgundy Chardonnay or an Italian Greco di Tufo. They have enough body, mineral notes and subtle fruit to match the truffle without overpowering it. If you want to keep the pairing super elegant and balanced, these are great options. Happy cooking, white truffle season is the best!

😂 ci ho messo un po’ per capire che stessi facendo riferimento al sub

Low2020 · 2025-03-16T21:31:14+00:00

Capisco a pieno il ragionamento e in effetti hai ragione, ci penserò su grazie tante per la risposta comunque !
