Our experience with voice input in Tutorial for Glass
When you need to input data in Glass, voice is the natural way. For sure, engineers will imagine methods to connect it to a keyboard but nothing can beat voice. It's much more natural, intuitive and convenient than any other alternative. A very cool feature of a tutorial or digital assistant in ...

The T4G team is enjoying the Easter break. We hope you can also relax, to help, here you have a new blog post of Tutorial for Glass. The Web client is a differential element of Tutorial for Glass where the tutorials and digital assistants are composed.Surely, most users will never create content ...

Does anyone know if Twitter finally stopped supporting their Glassware? they, of course, disabled any new users several months back, but the app still worked if you didn't turn it off in MyGlass - which I never did. I haven't been getting tweets for the last couple of days.

I'm trying to program this Android phone app in which there is a button by clicking which I can open an app on a Google Glass that is paired with the phone. I was wondering how this can be done, if at all. Maybe through BLE or something?

Never have really thought about doing something like this before. I will start by saying that I am not sure this can be done. But, if you do have the Glass App running you can have the Android app discover the Glass by trying to open some sort of socket via Bluetooth and send data to and from Glass. Just thinking outside the box in case this can't be done ;) Good luck!

It sounds crazy but Tutorial for Glass service will offer glassware an open architecture
We're currently integrating the App and web client with the T4G API. If you remember this post, the API is a strategic element of Tutorial for Glass that will differentiate how we provide services. Instead of offering a close product, which does not offer you any options and all you can do to ...

Probably a silly question, hope anyone can help with me:
After I install an app on google glass using eclipse and I can check it using "adb shell pm list packages -f" in Mac terminal and saw the app already be installed. But I still cannot find it in glass menu.

I know that when I side loaded apps it took a bit for them to actually show up, not only that but I had more success with using the gdk to load to app rather than adb for some reason.

"Does my Glassware need a web site to be approved?"
I was chatting with a friend earlier today about the process of Glassware review and Google's required materials for submission. One thing she was asking was about the need for a web site to accompany the project - which is primarily to be used, upon approval and listing in MyGlass, as your documentation, which your listing will link to as the Support page.

I obviously can't speak for Google, but in my own experience, this doesn't have to be a full-on professionally-designed web site. While many Glassware vendors go this route, you don't necessarily have to. With my projects, I've previously listed simple resources such as the GitHub README page for my project, or the GitHub wiki for my project, or GitHub's amazingly simple Pages feature, which auto-generates and themes a really nice-looking content based on your project. I haven't gotten dinged about the content being irrelevant or insufficient, so it's a cool tip to pass on. It's not the most-polished approach, but seems to work.

(Keep in mind these examples I've cited are basically all the same content, which took me an extra 20 minutes to write-up prior to sending my Glassware off to be assessed.)

https://github.com/jasonsalas/TrendingTimeForGlass/blob/master/README.md
https://github.com/jasonsalas/TrendingTimeForGlass/wiki/Tech-talk-presentation

The bottom line is that it's required you include some sort of helpful information your users can refer to when you get approved, but this doesn't have to be another project in itself.

Sidepack is at Nextgenlens!

Curious what side pack is all about?
SidePack is an external wearable battery pack for Google Glass. SidePack houses a 500 mAh battery allowing for extended use of Glass. SidePack slides onto the left side Glass with frames or no frames. Once slid on the microUSB cable wraps around the back of your neck doubling as a lanyard. Charging SidePack is easily done by plugging in a microUSB cable. SidePack's unique glowing case quickly let's you know the current battery status.

How do you use the Glass browser?
When +Allen Firstenberg and I were putting our book on Glassware design together, we drafted a chapter on using the on-board browser. It's one of the most-polarizing topics within our community - some see it as necessary and helpful (since you'll need to go to the web at some point), while others find it to be a clunky implementation and contradictory to the wearable mindset.

Not too many people have built specifically for the Glass browser - although +GlassFrogger is an HTML5 game that's a fantastic example of Mirror API Glassware to access the headset's on-board sensors and generated gestures and motion data, which are passed to an HTTP server running the game instance, in this case moving the character.

So participate in the poll based on your usage of the Glass browser, and if you've developed content or a service targeted to that viewport, share your experience and/or ideas in the comments. :)

My Google Glass and Mobile supports Bluetooth LE.Can I use the Bluetooth LE for two way communication between Glass and mobile.I try to send an image from Glass to mobile and again send response to Glass using bluetooth LE.Is it possible to do this?

About this community

Welcome to the Glass Developers Community! This is an unofficial Glass community for developers, where we can talk about applications, design, best practices, and developer related news. Google Glass will no doubt require a new approach to building mobile applications. Limited screen size, battery life, interactions and user attention span. Applications run on servers rather than the client, meaning backend developers now become frontend developers. Technologies like Google+ Sign In and Google Apps Engine becomes relevant for client developers in a completely new way. The goal of this community is to talk about these challenges, and promote building applications for Glass. If you know any developers interested in Glass, do not hesitate to invite them!

When developing for Google Glass, does anyone else stumble on getting GC_FOR_ALLOC for some allocations? Trying to figure out if I'm somehow leaking memory or if this is supposed to be normal.

Can anyone share the experience with boundary between developing glassware using GDK and Mirror API considering the native computing power of the glass? I want to run a Convolutional Neural Network feedforward on glass with real-time response but wondering which to choose.

If you need access to camera, Mic, etc... actual hardware requires the GDK

Here's a slide from the folks at Mozilla Research working on virtual reality for the browser (https://air.mozilla.org/channels/vr/). It's germane to our work as wearable developers in building immersive experiences for Glass in clarifying what those types of experiences should actually be.

An always-interesting talking point about +Google Glass has been its web browser. Unlike many topics within the Glass community, the browser tends not to be a polarizing issue – in my experience, opinions on the user agent often skew towards the negative, or even more damning, complete apathy (indifference being a fate worse than death for a consumer product). Admittedly, I’m an outlier – in countless conversations throughout Glass’ beta lifespan, whenever the topic of the Glass browser came about I’d typically be The Guy to fly the flag in defense of it. As in, the only guy.

When +Allen Firstenberg and I were writing Designing & Developing for Google Glass (http://www.amazon.com/Designing-Developing-Google-Glass-Differently/dp/1491946458), we initially dedicated a chapter to web access within the head-mounted display. And while in terms of capabilities the Glass browser stands toe-to-toe with other mobile browser platforms, two concerns always bubble up: How is most web content presented in such a small viewport?, and Does the experience of surfing the web on Glass contradict the wearable goal of microinteractions? That’s what we sought to investigate.

Sadly, our material was destined for a place on the cutting room floor, as it just didn’t jive with the rest of the discussion about the system…which in some people’s minds probably serves as a metaphor for the Glass browser overall. Ouch.

So here's our lost chapter, "Wearable web access with Google Glass". It’s still worth knowing what the potentials are for experiencing browser-based content on your head when you inevitably need to step out of the timeline and get on the Web.

Enjoy!

I've got some Glassware currently under review, and some of the feedback from the wearables team included this notable gem: a Share/Send option IS coming to the GDK. Such a facility to date has only been available through the Mirror API, using webhooks to link actions with designated sharing contacts, but it's certainly needed.

Great news!

+Trish Whetzel And now after pondering this some more, I'm going to protoytype the same service using the Mirror API (or a hybrid model) to see how it might all play out. I had some architectural/scaling/UX concerns at the beginning, and a live card in that regard is still the better choice, but with sharing being a major attraction, I might release it that way.

For a really good primer on immersive Glassware with great design, check out +CamFind's new app in MyGlass. It's an effective combination of the Glass user input tools, voice prompts, audible feedback, and card collections. It's a really well done translation of its mobile clients to the wearable model.

UPDATE - I made an interesting discovery: the vocalized cues from the female Glass voice say "Processing image" with an almost Canadian pronunciation on "processing" (try it to see what I mean), and the search results seem to lean towards British and Australian domains. 
 
Visual search on Glass with CamFind
+CamFind's new wearable app went live today, which lets you leverage powerful, non-intrusive image recognition while on the go with +Google Glass. I've stress-tested it a bunch of times this morning, and simply stated, it works.

It's not just that objects are identified, but how particular it is - CamFind can recognize branded items as well as generic objects, as the screencaps I've attached indicate. It seems to use a combination of colors, objects and text as input signals and then gets an idea of what the image is. Amazing.

I'm trying to find VERY obscure items to thwart it. but I haven't been able to yet! The core idea is implemented extremely well on Glass, using voice commands and the shutter button, and card bundles. Without any documentation, it's easy to figure out on the first try.

CamFind also maintains a very healthy API at https://www.mashape.com/imagesearcher/camfind

Enable the Glassware at https://glass.google.com/u/0/glassware/5008771194826684822, or use the mobile clients for iOS and Android at http://camfindapp.com.

It's a really well-put together project, +Joe Evans - shows you what you can do with a really good backend. :)

Some other visual search tools we've got for Glass: +Fancy's Glassware, which uses search-by-color and returns matching products in its database; and Preview, which does image recognition from a corpus of movie posters.

REALLY creative takes on the notion of wearable search!
