2, the principle of the air mouse: Map the X axis (Pitch) angular speed and Z axis (Yaw) of the air mouse to the moving speed of the mouse. Therefore, the way to grip the device must be determined in advance, such as which side is facing forward and which side is facing up. Sensitivity controlIt needs to be determined experimentally. It's even better if you can get the resolution of the screen or the size of the screen for dynamic adjustment.
3, first of all, the accuracy of the wireless mouse is not as good as that of the wired mouse, which may be shown as not moving smoothly, the mouse and the screen synchronization problem, and may even drift or drag. Second, wireless mice require additional power, increasing the cost of use. In addition, the problem of carrying a receiver is also a major inconvenience, and the two must work together, otherwise the mouse cannot be used. In commercial advertising, wireless mice are often over-packaged, less practical than expected, and sometimes misleading.
4, the evaluation of the advantages and disadvantages of the air mouse mainly depends on the positioning accuracy, smoothness and easy operation. Precision requires light movement to accurately point to the screen, smoothness depends on the sampling frequency, and a mouse sampling 120HZ provides a smooth experience. The user's subjective feelings, such as the use of distance, Angle consistency, key sensitivity and anti-interference ability, are also important criteria to measure ease of use.
5, in this case, the wireless keyboard and mouse are not only not easy to interfere with each other, but also because of the use of dual-channel signals and not easy to appear signal "crash" situation. In addition, becauseOther wireless network devices rarely use the 27Mhz frequency, so the possibility of interference from other wireless devices is not large.
