IRA FLATOW: And now it’s time to play Good Thing, Bad Thing. Because every story has a flip side. Well you know how it is. You’re out with friends or doing something cool and you want to capture the moment. So you pull out your phone. You frame the shot and uh! Too late. The moment is gone forever. Well, what if instead, you just tap the side of your head because you’re already wearing a pair of sunglasses outfitted with a pair of cameras ready to capture a 10 second video any time you just happen.

Well, the company Snapchat has rebranded itself as Snap Inc. and unveiled what it calls Snap Spectacles. Here to walk us through the good and bad of the gadget is Josh Constine, Editor-At-Large for TechCrunch. Welcome to the program.

JOSH CONSTINE: My pleasure. Thanks for having me.

IRA FLATOW: OK so these look like regular glasses, but with a couple of video cameras in them?

JOSH CONSTINE: Yes. On one side of the frames they’ll have a video camera and on the other side there will be a little warning light that will show people that you’re recording them, which is very important considering the last time that people tried face computers, Google Glass, there was no real clear indication that you were recording someone, and that made people very nervous around them.

IRA FLATOW: Now say, is this just supposed to be a big toy for us to use? Is it for work?

JOSH CONSTINE: From one perspective, you could say it’s a toy, something that people are just going to use at music festivals and barbecues. It’ll be about $130. And you know, it’s not going to be that important because you already have a camera on your phone. But from another perspective, you could see this as Snapchat trying to own the camera. Right now, it has to go through your iPhone or Android phone’s camera and it doesn’t have nearly as much control over the experience.

This way it can build whatever type of camera it wants. So in this case, it’s a 115 degree wide lens camera that actually records in circular video, a video format no one’s ever seen before. That way when you watch it on your phone, you can turn your phone and any directions, portrait or landscape and it will always be full screen.

IRA FLATOW: That’s the good thing. What’s the bad thing here?

JOSH CONSTINE: I think the bad thing here is that people are not really used to having to suddenly be on camera. When we’re in normal life, if you do something that’s maybe a little bit risque or strange or weird looking, nobody’s holding their camera up around you, you don’t have to worry. Because if they do want to record you, they’re going to have to pull out their phone or pull out their camera and in those few seconds, you’re going to have time to change your behavior.

But with this, people will be wearing these glasses at all times. All they have to do is quickly tap the side of the glasses and suddenly you’re on camera. That’s going to be pretty nerve wracking for some people. If you remember, there were bars and places that put up no Google Glass signs. And somebody even got punched in the face over wearing them because some people just don’t want to be on camera.

IRA FLATOW: You’ll see these are very distinctive sunglasses. You can see who’s wearing them. I guess you will go hide or something if you see somebody coming in if you don’t like that.

JOSH CONSTINE: I guess, but you know, the sunglasses style for teens right now is very outlandish. They’re covered with weird features all over them, strange little bumps and curves, and so it might not necessarily be instantly obvious that somebody is wearing these. But while Snapchat’s younger teen users might have no problem with being on video, especially because when you’re being recorded by Snapchat, it’s usually going to disappear within a day of somebody posting it. It’s not like somebody recording it forever on YouTube. But at the same time older people, anyone who’s exposed to this is probably going to get pretty freaked out.

IRA FLATOW: What about– are they two cameras? Can you make a 3-D picture out of the two cameras on the glasses? That would be terrific.

JOSH CONSTINE: There’s actually only one camera on the glasses right now, but down the line Snapchat has paid a lot of money to hire a bunch of augmented reality experts, which it’s using to add features to its normal app, like being able to stick an emoji to something and it moved with that object no matter where or how your camera moves. And one day Snapchat could definitely build augmented reality into these glasses so you could see stuff on the lenses rather than just being clear sunglasses.

IRA FLATOW: Well, give me those two cameras on the iPhone at each end, so I can take a 3D picture, and I’m in with this stuff. Thank you very much for taking the time to be with us Josh.
