Meta Cambria handle exposure, active tracking + multi tactile feedback scheme

Sadlyitsbradley stay 7 It was revealed at the beginning of the month ,Meta Cambria The handle may not be synchronized with the head display , Mainly because there are too many integrated parts , It's not perfect yet .

The next week , The news was quickly Meta CTO Andrew Bosworth Falsification , And said ： It will definitely start synchronously .

But then bradley Indicates that your message source is also updating messages synchronously , It seems to mean Starlet The handle progresses faster than expected . So ,bradley Send a forecast again Meta Cambria Head display and handle , From star chasers Starlet Handle CAD chart , Almost expose the whole internal structure . Of course, he also said ： There is more material in hand .

Review first bradley Some information points mentioned in the previous article ：

• 1,Meta The account system was released in the last article 48 Confirmed within hours , Indicates that the message source is reliable ;
• 2,Quest Pro The screen adopts the rotation scheme ,（ With inclined installation , Non horizontal ）;
• 3,Oculus Drive to join “META_HAMMERHEAD” equipment , Sources said , This is a Meta The next smart glasses , Code name “Hypernova”, Similar to ray ban smart glasses 2 generation , The main improvement is in audio , Positive and Luxottica cooperation , The release time may be 23 In the second half of ;
• 4,Starlet The handle and head display will not be delivered synchronously , The news proved to be wrong .

This article will focus on Starlet Handle , as well as Meta Cambria 's display . Next is bradley Predicted hardware parameter information ：

• 2 block Tianjin-3 QLED The screen , Monocular 2160x2160, The actual display 1800 x 1920,nimiLED Backlight , tilt 21 Degree of installation ;
• customized Pancake Lens ;
• Support Wi-Fi 6E;
• Support space audio ;
• 5000mAh Battery capacity （ Charge separately 、 There are two modes of charging the base ）;
• Set price 1500 dollar （ Head display 、 Handle 、 Charging board 、 Cable 、 Instructions, etc ）;
• Meta Connect The conference is scheduled to open ;
• 2022 year 10 month 25 Daily shipment .

Quest Pro Handle ：

• Qualcomm Xiao dragon 662;
• 3 Infrared cameras for Inside-Out 6DoF track ;
• built-in 3200mAh The battery , Support base charging ;
• Multiple groups of tactile sensors ;
• Pressure sensor ;
• Weight ratio Quest 2 heavy ;
• And Quest Pro The head display is released together , And provide separate packaging for sale （ about 300 dollar ）.

1,Starlet Handle

First bradley It means that the reason why the previous article made mistakes in the issue of handle delivery , Because Meta They were told internally ：Meta I have considered the sale of separate handle and charging board , It can also reduce the cost and price of the head display . in addition , The stoppage of China's OEM led to the slow progress of handle production .

1-1, Yes Quest 2 Support for

So ,Meta Have to make some choices . But others say , The biggest trade-off is to slow down Quest 2 Support for .

new Starlet Handle support Quest 2 It is still a problem to be considered , Because you may need special App To update the handle firmware .

bradley The message source represents ,Starlet Handle （2 individual ） And the retail price of the charging board may be 300 About $ .

1-2, working principle

From the previous Demo The video and only a few pictures have been known ,Meta Cambria The equipped code is Starlet The handle of is no longer equipped with a tracking ring , Working principle or previous passive tracking , Change it to Inside-Out Active tracking .

PS： In this paper bradley There is no mention of , Last year, netizens Samuliai Mining out information is ,Starlet Although the handle is Inside-Out track , But there is still infrared inside LED. This is also in the head display parameters ,4 The reason why the camera supports infrared capture .

1-3, Non removable battery

Quest 2 Handle adopts handle 5 No. 1 battery solution , It's convenient to change batteries , And the endurance performance is also excellent .

built-in 3200mAh The battery

and Starlet The handle adopts charging design , built-in 3200mAh Capacity lithium battery , So as to guarantee Inside-Out Stable （ Drive required SoC、3 A camera, etc ）.

Charging metal contact

The charging mode is based on three metal contacts on one side of the handle .

1-4, Multiple sets of tactile and feedback sensors

The reason is to postpone , Because Starlet The internal density is higher , And the tactile feedback scheme is also more complex .

Main motor （ Trigger position ）

The main motor is a linear vibration motor , For overall tactile feedback ; The auxiliary motor is located under the thumb , It is also a linear vibration motor , For kneading 、 Grasp and other simulation ; Voice coil motor beside the battery , Used to simulate tactile feedback with higher accuracy .

The pressure sensor at the bottom of the handle

There is also a pressure sensor at the bottom of the handle , Use in a way similar to Quest 2 Handle upside down for handwriting , May be in VR、MR Interactive use of handwriting and painting in the scene .

2,Meta Cambria display

before bradley guess ,Meta Cambria Solutions that may rotate the screen , The purpose is to increase the vertical direction FOV.

Now his source says , This conjecture is correct , The horizontal deflection angle between the display screen and the fuselage is 21 degree . And this design , It also helps to reduce production costs .

Quest The tilt screen scheme has appeared in the firmware

Previously, engineers found Quest A new screen message appears in the code , Or for miniLED. Guo mingpeng also said ,Quest Pro The resolution is monocular 2160×2160.

bradley said ,Quest Pro Screen internal code “Tianjin-3”, It is combined with quantum dot technology QLED+mini LED panel .

because mini LED The need for local dimming can improve contrast and brightness , But there are also higher requirements for the algorithm . So Meta Further improve the algorithm , The purpose is to achieve something similar to OLED Of “ All black ” According to the effect .

because Pancake Light efficiency is very low , Therefore, the requirements for brightness are higher , The duty cycle is about 10%. in addition Meta Engineers also need to put a lot of work on the screen , To achieve good display effect .

About the resolution of the screen , The physical resolution may be monocular 2160×2160, But because of inclined installation , Actually show monocular 1800×1920.

With Meta Cambria Promotion of mass production ,bradley It also means that the focus will not be on Cambria On , even to the extent that Quest 3 Some information of .

Eureka865 Hardware information

stay Quest 2 Public test channel v43 Pushing , Discovery code Eureka865 (Quest 3) A resolution of 4128×2208,LCD The screen , Than Quest 2 Pixel increase 30%.
