Ask Hackaday: Is Anyone Sad Phone VR Is Dead?

November 13, 2019 by Donald Papp 92 Comments

It’s official: smartphone-based VR is dead. The two big players in this space were Samsung Gear VR (powered by Oculus, which is owned by Facebook) and Google Daydream. Both have called it quits, with Google omitting support from their newer phones and Oculus confirming that the Gear VR has reached the end of its road. Things aren’t entirely shut down quite yet, but when it does it will sure leave a lot of empty headsets laying around. These things exist in the millions, but did anyone really use phone-based VR? Are any of you sad to see it go?

Google Cardboard, lowering cost and barrier to entry about as low as it could go.

In case you’re unfamiliar with phone-based VR, this is how it works: the user drops their smartphone into a headset, puts it on their head, and optionally uses a wireless controller to interact with things. The smartphone takes care of tracking motion and displaying 3D content while the headset itself takes care of the optics and holds everything in front of the user’s eyeballs. On the low end was Google Cardboard and on the higher end was Daydream and Gear VR. It works, and is both cheap and portable, so what happened?

In short, phone-based VR had constraints that limited just how far it could go when it came to delivering a VR experience, and these constraints kept it from being viable in the long run. Here are some of the reasons smartphone-based VR hit the end of the road: Continue reading “Ask Hackaday: Is Anyone Sad Phone VR Is Dead?” →

Build Your Own Gear VR

February 5, 2015 by Eric Evenchick 31 Comments

With Samsung’s new Gear VR announced, developers and VR enthusiasts are awaiting the release of the smartphone connected VR headset. A few people couldn’t wait to get their hands on the platform, so they created, OpenGear, a Gear VR compatible headset.

The OpenGear starts off with a Samsung Galaxy Note 4, which is the target platform for the Gear VR headset. A cardboard enclosure, similar to the Google Cardboard headset, holds the lenses and straps the phone to your face.

The only missing part is the motion tracking electronics. Fortunately, ST’s STM32F3 Discovery development board has everything needed: a microcontroller with USB device support, a L3GD20 3 axis gyro, and a LSM303DLHC accelerometer/magnetometer. These components together provide a USB inertial measurement unit for tracking your head.

With the Discovery board strapped to the cardboard headset, an open-source firmware is flashed. This emulates the messages sent by a legitimate Oculus Rift motion tracker. The Galaxy Note 4 sees the device as a VR headset, and lets you run VR apps.

If you’re interested, the OpenGear team is offering a development kit. This is a great way for developers to get a head start on their apps before the Gear VR is actually released. The main downside is how you’ll look with this thing affixed to your face. There’s a head-to-head against the real Gear VR after the break.

CES: Building Booths And Simulating Reality

January 7, 2015 by Mike Szczys 15 Comments

My first day on the ground at CES started with a somewhat amusing wait at the Taxi Stand of the McCarran International Airport. Actually I’m getting ahead of myself… it started with a surprisingly efficient badge-pickup booth in the baggage claim of the airport. Wait in line for about three minutes, and show them the QR code emailed to you from online registration and you’re ready to move to the 1/4 mile-long, six-switchback deep line for cabs. Yeah, there’s a lot of people here for this conference.

It’s striking just how huge this thing is. Every hotel on the strip is crawling with badge-wearing CES attendees. Many of the conference halls in the hotels are filled with booths, meaning the thing is spread out over a huge geographic area. We bought three-day monorail passes and headed to the convention center to get started.

Building the Booths

Emotive Insights headsets

Slot-car “brain racing” with scoreboard

[Sophi] knows [Ben Unsworth] who put his heart and soul into this year’s IEEE booth. His company, Globacore, builds booths for conferences and this one sounds like it was an exceptional amount of fun to work on. He was part of a tiny team that built a mind-controlled drag strip based on Emotive Insight brainwave measuring hardware shipped directly from the first factory production run. This ties in with the display screens above the track to form a leader board. We’ll have a keen eye out for hacks this week, but the story behind building these booths may be the best hack to be found.

Oculus

Oculus Gear VX uses a Galaxy Note 4 as the display

Sophi Kravitz trying out Oculus Gear VR

[Ben] told us hands-down the thing to see is the new Oculus hardware called Crescent Bay. He emphatically mentioned The Holodeck which is a comparison we don’t throw around lightly. Seems like a lot of people feel that way because the line to try it out is wicked long. We downloaded their app which allows you to schedule a demo but all appointments are already taken. Hopefully our Twitter plea will be seen by their crew.

In the meantime we tried out the Oculus Gear VR. It uses a Galaxy Note 4 as the screen along with lenses and a variety of motion tracking and user controls. The demo was a Zelda-like game where you view the scene from overhead. This used a handheld controller to command the in-game character with the headset’s motion tracking used to look around the playing area. It was a neat demo, I’m not quite sold on long gaming sessions with the hardware but maybe I just need to get used full-immersion first.

Window to another Dimension

The midways close at six o’clock and we made our way to the Occipital booth just as they were winding done. I’ve been 3D scanned a few times before but those systems used turntables and depth cameras on motorized tracks to do the work. This uses a depth-camera add-on for an iPad which they call Structure Sensor.

It is striking how quickly the rig can capture a model. This high-speed performance is parlayed into other uses, like creating a virtual world inside the iPad which the user navigates by using the screen as if it were a magic window into another dimension. Their demo was something along the lines of the game Portal and has us thinking that the Wii U controller has the right idea for entertainment, but it needs the performance that Occipital offers. I liked this experience more than the Oculus demo because you are not shut off from the real world as you make your way through the virtual.

We shot some video of the hardware and plan to post more about it as soon as we get the time to edit the footage.

Find Us or Follow Us

We’re wearing our Hackaday shirts and that stopped [Josh] in his tracks. He’s here on business with his company Evermind, but like any good hacker he is carrying around one of his passion projects in his pocket. What he’s showing off are a couple of prototypes for a CANbus sniffer and interface device that he’s build.

We’ll be at CES all week. You can follow our progress through the following Twitter accounts: @Hackaday, @HackadayPrize, @Szczys, and @SophiKravitz. If you’re here in person you can Tweet us to find where we are. We’re also planning a 9am Thursday Breakfast meetup at SambaLatte in the Monte Carlo. We hope you’ll stop by and say hi. Don’t forget to bring your own hardware!
