Microsoft's latest research brings facial pulse, respiratory rate and temperature changes to VR

Florencio and Chueng are now investigating whether active light sensing can accurately detect informative biological signals (such as facial pulse/respiratory frequency and temperature changes).

(Aviation Network February 8, 2017) Improved VR and 3D immersive communication has been the cornerstone of Microsoft's long-term investment in this technology field, and has brought a lot of innovation.

Microsoft said that more immersive communication through 3D applications requires a huge leap in 3D geometry capture and exchange, which can only be achieved through continuous signal processing. At the heart of this work is the Collaborative Research (CORE) project between Microsoft and academic partners, including Dr. Gene Cheung, Associate Professor at the National Institute of Informatics, Japan.

Using depth sensing devices such as Kinect sensors, researchers have developed a way to better reduce noise and recover missing details in the image. Crucially, they discovered a way to exploit the smoothness of the graphical signal before enhancing the natural image (see Figure 1) and the depth image.

The left image is the original 4-bit image; the right image is the effect image after using the new method.

Dinei Florencio, a senior researcher at Microsoft Research Asia, has been working with Professor Cheung on "rate-constrained 3D surface esTImaTIon" and "precision enhancement of mulTIple 3D depth maps."

Florenicio said: "These two research lines are the most active projects in our recent cooperation. When we get the progress we need in immersive communication, I believe that Gene's research will bring some core contributions."

Other key members of the project include Cha Zhang and Philip Chou of Microsoft Research, and Pengfei Wan, a graduate student at the Hong Kong University of Science and Technology.

Florencio and Chueng are now investigating whether active light sensing can accurately detect informative biological signals (such as facial pulse/respiratory frequency and temperature changes). A key issue in the study was the ability to extend active light sensing to reveal the same details of shadows or remote human subjects.

Tao Mei, a senior researcher at the Microsoft Research Institute, said: "The project is very interesting because it attempts to estimate biosignals for more effective face-to-face communication. The main researchers have proposed a method of using completely non-contact and non-invasive active imaging - through A novel idea of ​​analyzing the thermal and depth images constructed in an active image sensing system in an interior is used to solve this problem.

Upon completion, Professor Cheung will disclose the research tool. Yingwei.com is looking forward to the continuous progress and achievements of the project. We hope that more researchers can explore this field, expand the frontier of virtual reality technology, and realize the holographic message transmission of Princess Leia in Star Wars in the future.
