Motion capture suit

A VPL Research DataSuit, a full-body outfit with sensors for measuring the movement of arms, legs, and trunk. Developed circa 1989. Displayed at the Nissho Iwai showroom in Tokyo

A motion capture suit (or mo-cap suit) is a wearable device that records the body movements of the wearer. Some of these suits also function as haptic suits.

History

Introduced in the late 1980s, the Data Suit by VPL Research was one of the earliest mo-cap suits in the market. Sensors stitched in the Data Suit were connected by fiber-optic cables to computers that updated the visuals 15 to 30 times a second. The Data Suit was ahead of its time, selling for up to $500,000 for a complete system (along with the EyePhone and the Data Glove).^[1]

Smartsuit Pro

The Smartsuit Pro by Danish company Rokoko uses an array of 19 embedded 9-degrees of freedom (9-DoF) IMU sensors to capture motion date from the person wearing the suit. This data is used to live stream user movement via WiFi, or record data to input into software such as Unity, Unreal Engine 4, or MotionBuilder.^[3][4]

Xsens

At GDC 2016, Xsens announced integration with Unreal Engine 4^[5] Later that month, Xsens collaborated with Dutch technology company Manus VR in order to showcase an immersive VR experience.^[6]

Holosuit

A bi-directional, full body motion controller with haptic feedback, Holosuit comes with a full body suit and can also be used separately as just gloves, jacket or pants.

G5 Mocapsuit

G5 Mocapsuit by AiQ Synertial is a 17-sensor IMU-based motion capture system with an option for 4-sensor 'Pincer Gloves'. Synertial partnered with 'AiQ Smart Clothing' of Taiwan, in 2018, to integrate fabric technology into its suits reducing significant amounts of sensor artefacts. GPS enabled. Sports Motion capture models use an Android app to manage onboard recording to calibrate 'later' as well as live streams data via WiFi & Bluetooth.
