ConstellationConstellationIn modern astronomy, a constellation is a specific area of the celestial sphere as defined by the International Astronomical Union (IAU). These areas mostly had their origins in Western-traditional asterisms from which the constellations take their names. There are 88 officially recogniz…en.wikipedia.orgis the Oculus method of tracking a user throughout a room. This is what lets the computer know where your headset and hands are in 3D space. Basically, any time you lean forward or backward inside a Rift headset and the experience responds, that’s Constellation at work.

Can the Oculus Rift Constellation sensor be repaired?

Nordic Semiconductor nRF51822 Bluetooth Smart and 2.4GHz proprietary SoC (also found in the Oculus Rift Headset) ON Semiconductor NC7SB3157L6X SPDT analog switch (likely) Oculus Rift Constellation Sensor Repairability Score: 7 out of 10 (10 is easiest to repair) Stand and visible light filter are removable and can be replaced if damaged.

What is the Oculus Rift constellation API?

These manufactures will be able to use the Constellation API to create their own positionally tracked accessories for the Rift . The first iteration of the system will be released with Oculus Rift CV1 in Q1 2015.

How does constellation work with the Oculus Touch and HMD?

Similar to Lighthouse, Constellation is able to track both the HMD and Oculus Touch controllers. Unlike Lighthouse, Constellation utilizes optical sensors that detect the IR LED markers on the tracked devices.

What to expect from Oculus Rift CV1?

The first iteration of the system will be released with Oculus Rift CV1 in Q1 2015. The Rift will utilize an Oculus Sensor that sits on top of a thin and malleable pole about a foot in length. The entire setup can be placed on a desk similar to a lamp. The sensor and its mount is black in color. It is small, sleek and looks like a small desk lamp.

What is visible light filter?

The visible light filter restricts the light coming in to the image sensor to the IR spectrum, meaning the IR LEDs on the headband will shine bright like a diamond stars.

Can you shuck an IR sensor?

Teardown Update: Whoops! According to Oculus, you can shuck the IR sensor’s cowling by pulling the stand hardware off. When we got our second unit we took some channellocks and a vice grip to it and were able to free the hardware from the camera assembly.

Can a IR camera see without a filter?

Without the visible light filter, the sensor would see what our fancy IR camera sees—and would have a hard time picking out just the pattern of LEDs to determine the Rift’s position and orientation in space.

How Does It Work?

Oculus Rift uses the IMUs as the primary positional tracking system. It responds extremely quickly and updates at several hundred Hz (1000Hz sampling, 500Hz reporting). However, IMUs drift due to double-integration of error. The drift is on the order of meters per second. So Constellation do is squelch that error 60 times per second (both have a 60Hz global position update rate) using their optical sensors to provide an absolute position reference.

What does the Oculus sensor look like?

The sensor and its mount is black in color. It is small, sleek and looks like a small desk lamp. IR LED markers are placed on the HMD and Oculus Touch controllers so they can be tracked by the sensor (s). Oculus Touch will require an additional camera sensor.

Is Constellation a high speed tracker?

For Constellation, high-speed position tracking performance is down ENTIRELY to IMU performance. It wouldn’t be possible at all without another absolute reference system (optical, magnetic or otherwise) but it’s the IMU that’s doing the grunt-work.

Does Oculus Touch require camera?

Oculus Touch will require an additional camera sensor.
