How to realize ray movement with Vive handle

How to solve the problem of 1 and HTC Vive lighthouse bracket?

I learned at the HTC Vive Summit that the HTC Vive Lighthouse has a special support. Even though I haven't found an access channel on the Internet for a long time, I also found that other friends who use HTC Vive have also encountered this problem.

So I can only DIY one myself. According to the use requirements of the lighthouse, as long as it is fixed at a height of 2 meters, the angle between the laser emitting surface of the lighthouse and the wall should be about 120 degrees, and the distance between the two lighthouses should not exceed 2.5 meters.

HTC Vive originally came with a pair of small universal brackets that can fix the lighthouse on the wall, but considering the flexibility, it is better to choose a movable bracket. So, we removed the brackets of the two fill light lamps in the studio, and then fixed the attached small universal bracket on the fill light lamp bracket with adhesive tape to realize the universal adjustment of the lighthouse, and that's it (although it's a little ugly, make do with it ... the effect is as follows).

Of course, this is not the only way, as long as you can find a bracket about 2 meters high. It is also a good solution to choose a tripod with a fixed camera or DIY a pair of pipes yourself.

2。 What happens when I use a graphics card below GTX 970?

Officially recommended, the lowest graphics card to run HTC Vive is GTX 970. Because the adapted host hasn't arrived yet, let's try it with a computer with ordinary configuration for the time being. CPU, memory, etc. It basically meets the requirements, mainly because the graphics card is not good (the graphics card is NVIDIA GT 620). Therefore, during the equipment inspection, although the handle and lighthouse are normal, the head display can't be recognized no matter how it is configured, and the head display indicator always flashes red.

Later, I found a game book with better configuration to test. The graphics card is GTX 650M. During the whole wiring process, everything goes smoothly, and the head indicator light is green and normal. After the platform starts, the head display is still unrecognizable. A screen in the head-mounted display can display the projected image of the host computer, but it still cannot be used. This is largely because the official only adapts to the drivers of GTX 970 and above graphics cards.

3.208 error code

The 208 error code is a traditional HMD (Head Display) error message. The main reasons for this error are:

1。 The video card is not updated to the latest driver version:

2。 The graphics card is GTX970 or below;

3.3 There is a problem. HDMI cable connection.

In short, it is to prescribe the right medicine, check every mistake and solve it quickly.

4. 108 error code

I don't know if my partners have encountered this kind of error. I found this kind of error several times during the installation process, and later I found it was a USB driver problem in official website according to the code error.

After the head display is connected to the host, the host will automatically install the USB driver of the head display. If not handled properly, problems will occur:

1。 The host USB port is damaged, and the solution is of course to try again with another USB port;

2。 The network connection is not smooth. If the network is not good, the driver download may be interrupted. Please keep the network open at this time.

3。 Anti-virus software startup, etc. If the anti-virus software or driver wizard is started in the background during the automatic installation of USB drivers, the software may prevent the installation of drivers. At this time, it is best to close this kind of software before operation.

Some problems encountered in use

1。 The head-mounted monitor is enabled, but it is not located.

This is likely to happen if HTC Vive is used in an environment with obvious reflective objects.

The reason is that the lighthouse uses the principle of laser reflection to locate the head display and other equipment. If there are such reflective objects in the environment, such as mirrors, polished floors, glass ornaments, etc. , which may affect the normal work of HTC Vive.

The solution is simple, that is, get rid of all the reflective things in the room or change rooms or go outdoors.

(The room that was first used cannot be used because of glass walls, reflective floors and other reasons. )

Later, a yoga mat was laid on the floor, and the glass was covered by the wall, so it returned to normal. )

2。 Please try to avoid shaking the lighthouse bracket.

When you experience HTC Vive, even if all irrelevant things in the venue are removed, sometimes the game is played too hard and you will inevitably encounter other things. You need to pay special attention not to shake the lighthouse bracket.

Because there are physical equipment such as motors in the lighthouse, if the lighthouse shakes too much during work, it may affect the normal positioning of the equipment and lead to misoperation of the application. Although the system itself has the function of "protective wall", in order to experience smoothly, it is best to take some avoidance measures, such as making the area a little farther from the lighthouse or making a protective fence when delineating the safe area.

3。 Unrecognized handle.

If you can't recognize the handle just after installation, one reason may be that the handle is dead, which is reflected in the fact that the indicator light for starting the handle is red, so you can recharge it at this time.

Another reason is that the firmware version of the handle is low. If there is such a problem when the system identifies the device, a prompt will appear. At this time, just connect the handle to the computer with a data cable, and then click the firmware update to solve the problem.

However, there is such a problem. For example, a handle firmware is normal and a handle needs to be updated, but the system does not prompt which one it is, and the handle end does not display it accordingly. At this time, you can only try one by one. If you are prompted not to update after connecting to the host, it is another handle.

Some unresolved problems

How to make the earphone end of the head display and the external speaker sound at the same time?

In order to improve the experience of users and onlookers at the same time, we hope that the partners who play and watch can hear the sound in the game at the same time, but we have no choice but to find a way to solve it, either headphones or speakers.
