When Will Most Games Be Replaced by Realistic Virtual Reality Experiences?

The future of virtual reality (VR) seems promising with the ability to cross the uncanny valley, where avatars can behave like humans without appearing strange or horrid. This article explores the challenges and recent advancements in making VR experiences as lifelike as possible.

From Photorealistic Models to Realistic Avatars

Professional 3D modeling and animation tools have long been capable of rendering super photorealistic scenes, houses, rivers, and various effects that are increasingly indistinguishable from reality. Major HMD (Head-Mounted Display) producers like Oculus have achieved significant advancements, such as dynamic focal planes, which enhance the fidelity and virtual comfort of VR content.

However, the challenge lies in the human characters, especially the faces. Despite the ability to model photorealistic human models, these models cannot currently reproduce the complex facial expressions that real humans can. A typical human possesses 43 facial muscles, enabling 10,000 distinct expressions, with over 3,000 being emotionally meaningful. Humans also have an incredible ability to detect emotions based on these subtle facial changes.

Leveraging Real-Time Facial Expression Detection

To overcome this challenge, advancements in hardware and algorithms are focusing on real-time detection and decoding of human facial expressions to reflect them on avatars. MindMaze, a leading computing and neuroscience company, introduced the MindMaze Mask in 2022. This ring of electrodes can be installed into HMDs and detects facial expressions by analyzing which parts of the face are contacting the detectors and the pressure applied. The avatar then reproduces one of 10 facial expressions based on the detected data.

This approach represents a promising and exciting step forward. Nevertheless, achieving complex and nuanced emotional expressions in VR avatars remains a significant challenge.

Real-Time Facial Expression Detection and Its Impact on VR

As the technology progresses, VR developers are focusing on these real-time facial expression detection solutions to help cross the uncanny valley. The uncanny valley is the phenomenon where highly realistic digital depictions of human beings appear almost — but not quite — real and can cause a strong negative emotional response from viewers.

Avatars that are visually realistic but without behavioral realism can appear unsettling and even frightening. This has led VR developers to opt for more cartoonish characters, sacrificing visual realism for comfort and acceptance.

The quest for realistic avatars continues, with ongoing efforts to develop better hardware and algorithms. While the MindMaze Mask is a significant step, real-time reproduction of complex emotions is still some way off.

Conclusion and Call to Action

As VR moves closer to achieving true realism, the industry is making strides in providing more lifelike experiences.
