What is motion capture?

Motion capture (sometimes referred to as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In filmmaking and video game development, it refers to recording the action of actors and using that information to animate digital character models in 2-D or 3-D computer animation. This process has been very successfully employed in collaborating on extraordinary performances in films such as Avatar, Lord of the Rings, and World War Z.

What can we use the BLE motion capture for?

BLE motion capture has an extensive range of uses throughout numerous industries, together with:

Film and Gaming – motion tracking is used to record the movement of actors and transfer them onto digital or computer-augmented characters.

Sports Activities Therapy and Healthcare – Healthcare specialists can use motion capture to analyze the motion of patients and diagnose problems i.e gait analysis.

Military – when combined with virtual reality, motion capture technology has been used to enhance military training experiences.

Medical & Health - This type of application allows the players of VR somatosensory games to have a more relaxed and enjoyable experience or allows some people who are inconvenient to operate the hand mouse to use the computer through head movements.

How does motion capture work?

To capture motion, mo-cap specialists place sensors all over a person. These track and record their movements, allowing them to be mapped on a computer screen in real-time as a virtual 'skeleton'. Animators then use computer programs to overlay information on top of the movements, creating a virtual set for the movement to take place in.

Why BLE Motion Capture?

Due to the recent advances in wireless communication, reducing sensor sizes and improving energy storage techniques, the vision of a pervasive Wireless Sensor Network is a step closer to becoming a reality. Developing the motion capture technology requires advanced information management and body sensor networks, which can enable remote monitoring of patients at home. That’s why we need BLE motion tracking or capture. The BLE technology will help the motion capture more effectively, accurately and reliably.

Sensing data through RF-star’s BLE modules

The combination of sensor technology and Bluetooth communication is realized in more and more applications. VR motion navigation system and head-mounted wireless mouse system are sensitive to the movement of limbs or head through sensor technology. The sensing data is transmitted through RF-star’s BLE modules and Dongle devices, and finally obtained by the PC to realize data analysis.
