Lilygo T-Glass
lilygo.ccI had access to a Google Glass device through the university I worked for. This looks a lot simpler to develop for, and probably a good deal more usable as a heads up display for random stuff. Not to mention shockingly less expensive. Battery life on the Glass was also very poor. This can only do better on the battery front.
Interesting to see this here. I've got one on order, with the intention of making a google maps direction HUD (→ 0.3 Boren Ave) for cycling as I never remember which are the ideal turns, dislike watches, and think it'd be fun.
Overall, the lilygo ecosystem is a lot of cool ESP tech, with surprisingly poor software and community support.
wouldn't an audio cue be superior?
There are three issues I have with audio queues:
- it's an unexpected mental context switch - if I'm concentrating on anything else, it takes a moment to switch to interpreting directions, sometimes enough to miss information
- if the traffic is not smooth, the distance becomes harder to judge - the turn is in 2km, but I did two stops, so how far is it now?
- "third left" becomes vague if you've passed a left while the message is played - was that included or not?
Constant information you can reference at any point is so much better for me. (Although a "tell me the directions again right now" button would solve some of them too)
hang on. we're talking about on a bicycle.
- a HUD visual would have the same context switch
- distances would be in half-blocks.
- a repeat direction button on the handlebar (or vox) would be easy
> a HUD visual would have the same context switch
I disagree. With visual I can choose to look at the directions whenever I want to whereas an audio cue comes out of no where and is distracting to me. I can filter out my phone in my car showing directions and look over at the phone mount whenever I need to but I always turn of audio cues because they drive me crazy when they interrupt what I’m thinking about and/or listening to.
Via headphones? Not in traffic, ideally. Sounds dangerous
it's for a bicycle. for the HUD you have to wear the device. so i was thinking the same for audio. you can wear an IEM loop or also glasses with a loud enough speaker on the arm.
or it can be much louder and mounted to the bike.
It looks like the focus here is managed in the simple way with the distance. Are there any optical tricks to make the display closer (less sticking out), but still fake-distant? I know displays in cars and serious HUDs do a bit of mirror magic to "redirect" the distance, but that would make the side more bulky. Are there any other good ways?
Fresnel lens lined up with it on the glasses, or bifocals?
