OFweek wearable device network news Oculus Rift family's last partner (currently known) - Oculus Touch also began to accept the booking on December 6. This not only marks that the Oculus Rift owns a complete set of equipment (even one more Xbox handle) like the HTC Vive, but also the prices of the two products are on the same starting line.
VR (Virtual Reality) is a technology that takes immersion as its core. Apart from satisfying the audio and visual enjoyment of users, touch and interaction are equally important. At present, many VR head-display devices have introduced their own handles (or controllers). Compared with products that use traditional gamepads or keyboards and mice, they are more interactive and user-friendly at the interactive level, enhancing immersion and allowing users to have virtual reality. In the process of experience, "do not play". Of course, because the industry is not standardized, the handles of different manufacturers vary greatly from form to function and are difficult to be compatible with each other. Although the handle cannot be a deciding factor in buying a certain head, but at least it is also an important indicator, then this time with the "Bone Surprise" Oculus Touch, a look at the controller what are the door!
Ifixit is a well-known foreign dismantling website. It has already undone the Oculus Rift and HTC VivePlayStation VR. Although Oculus Touch has some designs that make the ifixit team a headache, it eventually failed to escape from the clutches. Then let us watch together. At first glance, after the Oculus Touch "decomposes" it looks like...
The Oculus Touch kit is rich in content: two handles, an additional positioning sensor (Constellation), an AA battery, and an adapter for connecting the Oculus Touch and Rockband VR peripherals. However, this game, which allows White to experience the fun of playing guitar, is not included in 53 games that are "mothering" with Oculus Touch. Players may also need to wait patiently for some time.
To learn more about the Oculus Touch position tracking, itixit moved out of Spectrespecs infrared observation technology, which can see the LED dot matrix on the handle through an infrared camera.
On the Oculus Touch, the LED dot matrix is ​​identical to the head, which can be captured by the positioning sensor and determine the position and direction. The special shape is not easy to be blocked, which makes it easy for the sensor to capture the signal and improve the accuracy.
This handle uses AA batteries (each battery), and the back shell is fixed with a magnet that can be easily removed. To further ensure the battery position there is an auxiliary rubber bumper. It is easy to remove.
The relevant product information is also printed in the battery compartment.
To continue dismantling down requires the use of tools and unscrew the screws. However, simply dismantling did not successfully access Oculus Touch, so ifixit changed its mind and started from the top.
The fixing of the top uses a painful adhesive, and there are also hidden screws. To open the handle from the top, the first step is naturally to soften the adhesive, then open the cover to discover the shadow screws, switches, metal pads, and the first IR LED.
After the top screw is removed, the protective cover on the handle can be removed and the internal dense components can be seen.
Go to the next plastic screw on the uplift ridge strip to take it down.
Just want to remove the cable with the LED light seems to be with the glue for a resistance, this time do not need to heat, you can slowly open.
There are 22 infrared LEDs on this cable and each has a tag and a bar code.
You can now remove the battery compartment.
There is also a circuit board that needs to be melted by soldering iron to be removed.
In this small circuit board, in addition to several passive components, there are some empty pads, perhaps adding certain components for specific needs.
Hexagonal test lattices are also on the other side of the board.
Next, heating and slicing are required to remove the linear oscillator. Ifixit said that oscillators can now be seen on mobile phones, laptops, and VRs, and it is clearly a trend to simulate touch through vibration feedback in the future.
In addition to vibration feedback, you need to use some necessary buttons and joysticks to achieve interaction. The rocker of the Oculus Touch is called "brain" by the ifixit. The fixation is naturally very secure, but it does not affect its flexibility.
From the Oculus Touch can still find out the shadow of the Xbox, such as the XY/AB buttons on the two handles. With further dismantling, ititeit also unlocked the mystery of how Oculus Touch supports gesture recognition - the capacitive sensing circuit. There are multiple buttons on the handle, with the Dott shape allows the user to put the finger in the corresponding position during the grip, and once the finger off the button, the capacitive sensing circuit will produce a corresponding signal, and finally seen in the user In the virtual world, changes in gestures are made as close as possible to reality. Of course, in order to achieve the above functions, there are many chips on the circuit board that need further introduction:
The red box is a Nordic Semiconductor nRF51822 Bluetooth module;
Inside the orange box is the Analog Devices AD7147 single-electrode capacitive sensor controller
Yellow box for Invensense MP651 6-axis combination gyroscope and accelerometer
Finally, in the top circular area there is also a ribbon cable with two infrared LEDs (in the red box below), so that there is a total of 24 IR LEDs on each handle.
The orange rectangle in the figure below is a visible light LED as the indicator light; the yellow square button corresponds to the menu key or the Oculus home key on different handles; the green square box is the corresponding contact point in the thumb area. Whether or not the thumb touches the capacitive button, when the player experiences it, they can like it in the virtual world (vertical thumb).
Here, Oculus Touch is completely "decomposed". Overall, the difficulty of dismantling lies between the Oculus Rift head-up and positioning sensors.
The advantage of Oculus Touch in dismantling and repairing in the later period is that: AA batteries are used and replaced, and the magnetic cover is firm and easy to remove; a relatively uniform type of screw is used for fixing, which reduces the difficulty of disassembling. In contrast, the use of adhesives, welding to fix and many fixing screws, and the fixing point being “hidden†have increased the difficulty of disassembly and repair, and even slight care may cause damage to the handle.
