“…This can be compared to the best strategic-grade fiber optics gyroscopes (FOG) with instability levels (at 10 4 seconds) in the 10 −10 rad.s −1 range (Refs. 88,142,143 ), or to hemispherical resonator gyroscopes (HRG) with comparable performances 144 . The manufacturers of gyroscope usually characterize instruments with the angular random walk (ARW) specified in degrees per square-roothour and the bias instability expressed in degrees per hour.…”

“…For example, in the FOG of Ref. 143 , the ARW is 70 µ • / √ hr (20 nrad.s −1 .τ −1/2 ) and the bias instability is 80 µ • /hr at 8000 s. For MEMS gyro, the typical ARW is 0.02 • / √ hr and the bias instability is 0.05 • /hr at 1000 s. To refine the comparison, it is worth mentioning the importance of additional properties of sensors such as dynamic range, number of measurement axes, robustness to the environment (vibrations, temperature fluctuations), level of integration and industrialization possibilities. A large research effort in these direction is required to enlarge the scope of applications of cold-atom gyroscopes.…”

The research on cold-atom interferometers gathers a large community of about 50 groups worldwide both in the academic and now in the industrial sectors. The interest in this sub-field of quantum sensing and metrology lies in the large panel of possible applications of cold-atom sensors for measuring inertial and gravitational signals with a high level of stability and accuracy. This review presents the evolution of the field over the last 30 years and focuses on the acceleration of the research effort in the last 10 years. The article describes the physics principle of cold-atom gravito-inertial sensors as well as the main parts of hardware and the expertise required when starting the design of such sensors. It then reviews the progress in the development of instruments measuring gravitational and inertial signals, with a highlight on the limitations to the performances of the sensors, on their applications, and on the latest directions of research.

“…This motion capture system with gyroscope is also equipped by accelerometer and magnetometer. Together they are called IMU (Inertial Measurement Unit) [20]. The screen recordings from the previous two experiments show the process to animate 3D model using two different techniques based on a reference of 59 seconds life movements performed by real performer.…”

3D animation is created using keyframe based system in 3D animation software such as Blender and Maya. Due to the long time interval and the need of high expertise in 3D animation, motion capture devices were used as an alternative and Microsoft Kinect v2 sensor is one of them. This research analyses the capabilities of the Kinect sensor in producing 3D human model animations using motion capture and keyframe based animation system in reference to a live motion performance. The quality, time interval and cost of both animation results were compared. The experimental result shows that motion capture system with Kinect sensor consumed less time (only 2.6%) and cost (30%) in the long run (10 minutes of animation) compare to keyframe-based system, but it produced lower quality animation. This was due to the lack of body detection accuracy when there is obstruction. Moreover, the sensor's constant assumption that the performer's body faces forward made it unreliable to be used for a wide variety of movements. Furthermore, standard test defined in this research covers most body parts' movements to evaluate other motion capture system.
