Jason opened the meeting by welcoming the two guest speakers from Microsoft, who joined via Zoom. They talked about Microsoft Soundscape.

Amos Miller introduced himself. He started off in the UK, and introduced Melanie.

Melanie Maxwell said that they are both calling in from Redmond Washington, and are both part of the Soundscape team. Amos explained that the team is spread out over the U.S. and the UK.

Amos began by describing how Soundscape differs from other GPS aps. We wanted to explore how we could use technology to enrich peoples’ awareness of their surroundings. How could we have a greater understanding of what’s around us, and where it is in relation to where we are, to aid with orientation, way-finding, and our experience out doors. The way we achieve that is through the use of 3D audio, or spatial audio. This means,  sound that you can hear, that sounds like it’s in space around you, not between your ears. You can imagine that if you were standing on a street corner, and there was a Starbucks across the road and to the right in front of you, you would hear the word, “Starbucks,” coming from that direction. Instead of Soundscape telling you there’s a Starbucks 200 metres in front of you and to the right, it will just say the word, “Starbucks,” and you will hear that it’s 200 metres in front of you and to the right, just from the nature of the way you hear it through the headphones. For the best experience, it does require stereo headphones, and we can have a long conversation about that; that’s definitely unusual, especially for our community when you’re out doors, and trying to hear the ambient sounds as well. There are very good solutions for that, so there is a lot of reasons why Soundscape persisted to advance the thinking and the experience. When you walk down the street, you will hear those call-outs in 3D around you, giving you that P.O.I. information. We’ll also talk about how you can navigate to your destination using what Soundscape refers to as the audio beacon.

Before I dive into that though, I’ll give some background to the project. I’m the Product Manager for Soundscape in Microsoft Research in Redmond. This work started out 4 or 5 years ago when I was still in the UK. I was involved with the local guide dog organization there, and working with them to try and figure out how technology can integrate into our own independence and mobility when we’re out and about, but in a way that enhances that experience. Some people from Microsoft started working with mobility instructors, and guide dog and cane users. We explored a range of ideas long before we figured out how to solve the problem. We landed on this notion of how important it is to enhance the awareness, but not tell the person what to do in that space. A lot of what orientation and mobility trainers will do with us is to work on a specific route, but especially how to perceive the environment, how we read the cues that the environment is giving us from a sound perspective, echo location, traffic noise, direction of the wind, the tactile feeling of the ground: all of the signals we can get from the environment in order to orient, and make good navigational decisions. The work that we did with Guide Dogs in the early days of Soundscape was really to see how we can build on that. The idea of sound playing a big role in the perception of the space, was really how this idea evolved. Soundscape as an ap, is the first incarnation of that idea.

The ap is free, and available from the Ap Store. It does rely on map data, and so it does need to be able to access that data. For the most part, it will download the necessary data from the environment that you’re in, and from that point forward it’s not using data. So it’s not constantly drawing on your data plan, but it does require one. We’ve tried to optimize it so that the data usage is minimal, and in certain situations, it will also work in areas where there is no data.

Bose frames are a very good way to get the stereo effect. Bone conducting headphones are another good way. EarPods or standard headphones will work, but they will block your ears to ambient sound. Putting it in one ear to keep the other ear free won’t be effective because you won’t get the signature 3D effect. Amos said that he personally likes EarPods because of their sound quality, and it’s possible to insert them lightly into the ear and still have ambient sound. Some sports headphones are a good solution too, Plantronics for example. This type of headphone rests around the back of your neck, and clips over the ear. They sit in front of the ear canal without blocking it. They’re used commonly by runners and cyclists.

Melanie then took over. She began by running through some of the core features. The demo she provides will be limited because it can’t be presented in proper 3D audio.

“I’m going to walk us through the home screen first. Our goal with anything we design is that we want it to be really simple to use, and accessible. One thing you’ll notice is that we don’t have a lot on the home screen. I’m going to walk us through the home screen. The, set audio beacon, is one of the largest buttons on the screen. There are also buttons for, my location, nearby markers, around me, and, ahead of me. There are two parts of Soundscape; there are automatic components, where you can put your phone in your pocket and hear things, and there’s an active component, which are the buttons on the home screen. For example, if you want to know more about your current location, you can tap the, your location, button. Tapping on it gives you information about nearby intersections, what direction you’re facing, and then what intersection is closest to you. If you’re inside, you might here that you’re inside. The callout will change depending on where you are. When your phone is in your pocket and you’re moving, Soundscape relies on directionality of movement from the phone itself.

Another callout we have is, what’s around me. You’ll get location names and distances of places around where you are. You can change a setting between metric and imperial. You have choices for the Soundscape voice as well, including a French Canadian voice. Soundscape uses GPS, so it will only work inside buildings if map data is available. Either way, accuracy inside a building isn’t going to be as good. We have had users make audio beacons inside buildings. This can work reasonably well in a very large building, but we’re not at a place of very good accuracy in buildings.

There are two ways of finding a building. One way is to create your own marker. This relies on the accuracy of GPS. We recommend that if you want to create a marker, walk around the location a bit, as in, walk back and forth in front of it, to allow the phone to get as pinpointed a location as possible. This should get your marker accuracy to within a few metres. You won’t get 1 metre accuracy. Don’t try to create the marker when you exit a building, because the phone won’t be pinpointed enough yet with GPS.

There is a more complicated way as well. Soundscape uses Open Street Maps, which is an open-source ap that anyone can update. A lot of the buildings in Open Street Maps have their entrances marked. If Soundscape can find a building entrance on Open Street Maps, it will default to using that. Adding something to Open Street Maps isn’t an accessible process unfortunately, because it’s visual map-based. If there’s a building entrance that’s particularly important to you, you could try to have someone go into Open Street Maps and enter it for you, and it will show up in Soundscape. Open Street Maps update themselves once per week, but it might take two weeks for it to show up in Soundscape. Markers that you create yourself with Soundscape show up immediately.

To create a marker at your current location, from the home screen, find the, mark current location, button, located near the top of the screen. Double tap that. If you start in a tutorial screen, you can dismiss it. A name will be automatically assigned, but you can edit it. Pressing done, means the marker will exist as a custom P.O.I. There’s another whole page of controls where you can edit and manipulate your markers.

This moves us on to a unique feature of Soundscape, beacons. Beacons are one way of navigating to a specific place. Instead of giving you step by step instructions for you to follow in order to find your destination, Soundscape creates a sound that emanates from the destination you’ve set, and you navigate from that. This is done by using a marker, and turning it into a beacon, then activating it.

Start by double tapping on the button on the home screen called, set audio beacon. On the next page, you have a few options. You can set an audio beacon on a marker you’ve already created, or you can enter an address that you want to find. You can also browse nearby places and choose one to place a beacon on. You can also filter nearby places by category, restaurants etc.

 

To set a beacon on an existing marker, from this page, double tap on the, browse your markers, button. Here, you can browse your existing markers. Double tapping on a marker will set it as a beacon.”

Jason added that he and Chris Chamberlin are producing a tech podcast, and one of their recent episodes was on Soundscape. In it, they do a stereo demonstration of setting and following a beacon. Listening to this episode with headphones will give a very accurate experience of using Soundscape.

Amos then opened it up for questions. One member reported that some of the stores Soundscape announced for her in real time, were closed. The response was that the ap is getting its data from Open Street Map, so if their data isn’t up-to-date, Soundscape won’t be getting accurate information. Amos made the point that there will always be a question mark between you and the technology. “In Soundscape, we try to stay on the right side of not pretending that we can do more than what we think we can. We’ll never give you an impression of greater accuracy than what we can actually give you with the technology. A great example of that is, if you’re navigating to somewhere and you get close, Soundscape will tell you you’re close, then turn off the beacon, leaving the specific locating of an entrance to you. There will always be cases where there’s a dissonance between the technology and your experience. We give you all the information we can, but you’ll always have to make sense of it based on your own senses. We had an early incarnation of the ap that tried to follow a road. Sometimes the data would be wrong, but testers would follow the beacon out into the middle of an intersection, even though all of their awareness of their surroundings tells them it’s not a good idea. All GPS aps will tell you to use your best judgment, and then they’ll give you instructions that are pretty difficult to ignore. We’ve always been very careful in the design of Soundscape, not to give the impression that it knows better than you about the space you’re in.”

A member asked whether they are considering adding functionality that would allow Soundscape users to update information in Open Street Map, using a Soundscape interface.

Melanie replied, “That isn’t something that’s on our immediate road map, but it is something we’ve discussed. There is a, send feedback, button in Soundscape where we welcome information. We can’t necessarily respond to every report by updating Open Street Maps, but we definitely do add our own updates routinely, so it’s worth reporting this way if you want to. Open Street Map is open source with a strong community, and we’ve found that if we flag a particular area as being poorly represented, the community will often step up to fill in the gaps. It may be useful for the visually impaired community in Toronto, to make contact with the Open Street Map community in Toronto to see if the two groups could work together.

Another member said that she finds it hard to operate the phone and work her dog. Is there another way to interface with the ap?

Amos responded that most of the information you need will be announced even with your phone locked and in your pocket. If you have the kind of headphones that have play/pause and fast-forward/rewind buttons on them, the play and pause button has a few functions. One press will mute or unmute Soundscape. A double press of that button will activate the, where am I, feature, and a triple press will repeat the last call-out. Bose Frames, Aftershocks and EarPods all have this functionality, and have good sound. We have worked hard for as much of a hands/free experience as possible. It’s a background or ambient experience for some users. Some people keep it on in the background while riding the bus and checking email. It’s a companion that you should be able to get used to without having to give it a lot of attention. Work on ignoring Soundscape

Soundscape does not work on Android phones. Jason and another member contributed that functionality on Android is important, because accessibility should mean being available on as many devices as possible. A member contributed that AMI research has shown that Android use among young people in the visually impaired community is higher, and rising. In general, iPhone use outstrips Android use in the visually impaired community in North America, but that’s definitely not true in other parts of the world.

Another member asked if there’s any consideration of using voice commands to run Soundscape. Amos replied that there are. IOS provides some even easier ways to do that now, with Siri shortcuts and so on. There are two reasons why we haven’t really got there. The first is that when you’re out doors in noisy environments, that’s not going to work so well, especially if your microphone isn’t quite where it needs to be, which can lead to frustration. Secondly, the direction of trying to minimize your need to even give Soundscape commands, is the goal as we try to optimize. There are certain situations, such as choosing a beacon, which is a handful when you’re on the go, and voice commands could simplify that. We look a lot at the telemetry of which buttons are being pressed and so on. When people are on the go largely, you don’t really need most of them. You don’t really need to pull the phone out and press buttons, especially with the headset buttons, but we do look at voice commands. It’s always good to hear people’s experiences and preferences in that regard.

A member asked if the ap will work with IOS13? Amos replied that it will, but be warned … There are a lot of warnings out there about IOS13 having a lot of its own accessibility issues. The recommendation is to wait a few days till IOS13.1 comes out.

A member said that she uses Bluetooth hearing aids, and that she was very impressed with how well Soundscape functioned with them.

Amos said, “We are both delighted to hear, we’re both smiling here.”

A member said he wasn’t clear how close or far you could be to a destination to use Soundscape, as it doesn’t give turn-by-turn directions. Should we be using it in conjunction with another ap?

Melanie replied that they have received similar feedback in the past. The current recommendation is that Soundscape can be used alongside other navigation tools. If you’re in a location that you’re not familiar with and you want a lot of detail about how to get there, Google Maps might provide really great turn-by-turn directions. You might then also use Soundscape to help you understand what’s around you as you move from point A to point B. When you’re in a space you feel more familiar with, you might know the general layout but you don’t know exactly where the building is. In that case you might set a beacon on the building and start making the necessary turns.

Amos added that you can do long walks with Soundscape, but that it’s really optimal around 400 to 150 metres. It’s often very good when you go somewhere using Google Maps and it tells you you’ve arrived, but you still don’t know where the building is. In that case, Soundscape can be very helpful. We do get the question of adding turn-by-turn directions to Soundscape, and we’re not ignoring that.

For the past year, we started to explore uses of Soundscape outside the area of city navigation and mobility. We started to explore, for example, the idea of using Soundscape for kayaking. You can use a beacon to keep oriented on a lake; you can hear where the shore is, or where you took off from. We’ve played around with trails and recreational experiences. We’re having a lot of interest and traction on that front. Personally, I think that the experiences people get in recreation are mind blowing. They’re just wonderful because of the level of independence it gives you. So if any of you are so inclined, I highly recommend for you to try it. We are doing some work with the local adaptive sports organization. We’ve set up a trial that enables them to curate a route which would then surface on Soundscape. They’re going to run their first adaptive sports kayaking program next week with Soundscape as a test. It’s something that’s different, and that we felt was very rewarding for participants.

A member contributed that the active tandem cycling and sailing groups in Toronto might want to connect with Amos.

A member asked what Microsoft is working on for the future of Soundscape.

Amos replied that the recreational aspect is something they’re really excited about, and also the Bose Frames. We have talked about a hands-free experience, and sensors built into the device that track your head movement, enabling us to improve the audio experience. Amos invited Jason, who has had the opportunity to try this type of Bose Frames, to describe the experience.

Jason explained that the newest Bose Frames will have a gyro/accelerometer in them. What it will allow you to do, is set a beacon in Soundscape, then locate it just by turning your head, and it’s really quite cool.

Amos added that it has some very interesting applications for what Soundscape can offer.

Jason asked how people can give feedback.

Amos answered that they can email soundscapefeed@microsoft.com and that comes to our team. There is also a feedback button in the ap itself.

Amos and Melanie signed off.

Jason then went through a few points.

All of the meeting notes are now up on the GTT website. He then demonstrated something that has been added to the website. Do not try this with Internet Explorer, you must use a modern browser. One of the links at the top of the page is for meeting notes. Jason opened the notes for May, 2019. Arrowing down from the main heading, you’ll come to a line that says, listen to this article, with a play button. This is a new feature, that will read you the article in the new Amazon Newscaster voice. If you would prefer a voice other than Jaws, or if you’re a large print user, this is an option. Jason did a demo of the high-quality voice. Any of the meeting notes you call up, will offer this option.

IOS13 was released today. If you have an iPhone6S or better, you  can run it. It’s probably a good idea to hold off on installing it. IOS13.1 should be out in 4 days or so. They released IOS13 a bit before it was ready, in order to align with the new iPhone release. IOS13 offers a lot of cool things. One of the coolest is that you can change all of your VoiceOver gestures. An example of why you might want to do this is, there are people who have a really hard time with the rotor gesture. You could change that to a different gesture. Also, if you have anything newer than an iPhone 8, you can turn the VoiceOver sounds into vibrations. There are several vibration patterns to choose from. We’re hoping to have a presentation on IOS13 next month.

Jason also announced a new tech podcast that he and Chris Chamberlin are doing. It’s through the CNIB Podcast Network, and it’s called the CNIB Smartlife Tech cast. It’s on most popular podcast platforms.
