CEDEC 2022 (Computer Entertainment Developer Conference, hereinafter referred to as Cedec), where game developers from all over the world gather to talk about development practices, the three days of the three days of the event, the PS5 VR HMD ‘PlayStation VR2 (hereinafter referred to as PS VR2)’, which was confirmed in early 2023 Related lectures were held.

The lecture, which was included by Takahashi Taisei Manager and Akiyama Kenssey Global Developer Technology Department of the Sony Interactive Entertainment (SIE) Global Product Planning Department, introduced how to save the entire outline, specifications, features, and features of PS VR2..

The lecture consists of the introduction of ‘introduction of hardware features of PS VR2 headsets and controllers’, ‘introduction of system UX of PS VR2’, ‘introduction of PS VR2 response title’, and ‘PS VR2-only contents’. The contents of the first half were not newly renewed to the contents introduced on the official website and YouTube, so we summarized the ‘PS VR2-only content production’ part, which includes the contents that developers can refer to.

▲ PS VR2’s device specifications, response titles related to the previous article can be found in the previous article.

The PS5 SDK is used for the development of PS VR2-only content. The PS5 content development functions can be applied as it is when developing PS VR2 content. The fact that you can freely take advantage of the fast processing speed, Tempest 3D audio technology, and highly graphic functions, which are characteristic of the PS5, is an indispensable advantage. Takahashi Manager will be able to create VR content with high immersion through close connection with the PS5 SDK, and that if you are already developing content that corresponds to the PS5 platform, it will not be difficult to create a title that corresponds to PS VR2. did.

The support of the middleware is also one of the things that SIE considers. The PS VR2 also corresponds to game productions using Unity and Unreal Engine, and can also apply multiple new functions included in the PS VR2 headset to the content.

The Sense Controller, a controller for PS VR2, is characterized by the same interface as the previously released VR controller. The button batch is also similar to other VR platforms, so the PS VR2 response is very easy.

High-definition rendering is one of the features that SIE proudly introduces. The announcement introduced the ‘Flexible Scale Laster Reason (FSR)’ feature of the PS5 GPU, which makes the screen center as high resolution and the surrounding area is seen as a low resolution. The feature, IR cameras on the PS VR2 headset, and gaze tracking features allow you to implement ‘foveded rendering’. It is a function that can improve performance by rendering only with high resolution and blurring the surrounding area by only the point where the user’s attention is reached. Takasahi Manager explained that there is also a support kit that supports developers who feel difficult to mount these functions.

In addition, when developing PS VR2-only contents, ‘headset feedback’ can be combined for visual and auditory production to increase immersion. The realistic haptic feedback function delivered through the motor mounted inside the headset is not attempted in other VR headsets that are previously released, so there are ampoule programs and demos for developers who can feel somewhat difficult. When shooting a machine gun or a shotgun, from normal walking to running or jumping. Since the vibration experience for each situation is included in the form of a demonstration, you can use each vibration type to find the degree of fit and how to use it directly.

Finally, the introduction of the PS VR2 development environment tool was followed. The first tool introduced is ‘VR Trace’. VR trace is a tool that can easily diagnose the problems of the VR application you are currently developing through capture and replay. You can also detect many problems that may occur in the development process and show them as highlights so that it is easy to see. In addition, the user’s eyes, the VR headset, and the trekking results of the controllers, are characterized by the ‘VR Trace’ tool that can be remotely worked anywhere in the replacement with dummy data.

The VR trace responds to the first new function applied to PS VR2. Representatives are the ‘Vibration View’ and ‘Leicester View’. The content developer allows you to check the vibration situation of the VR headset in real time with the vibration view function, and you can check the grid of the horizontal vertical LUT and dials with the Leicester View function.

In addition, the VR trace supports the ‘remote development environment’ so that the VR headset body can be prepared or maneuverable. The PC mouse can control the location and posture of the user, and can be developed by virtually implementing the environment that is operating the VR headset.

The next tool introduced is the PS VR2 Comfort sample. The sample is a learning tool that examines the problem of VR implementation that can cause visual discomfort. In the form of a problem, many cases that can lead to the discomfort of VR content users, such as the horizontal line does not match the actual environment or when the FOV is incorrect. At the same time, it is also possible to experience the phenomenon directly within the tool.

Takahashi Manager said the PS VR2, which is officially released in 2023 and various content information that can be found through the platform, will confirm the possibility of VR that will be widened in the future. Subsequently, developers who are willing to develop VR contents have worked together to express their ambitions to expect to expand the new VR world.
