What are the key factors in the Air mouse system design?

Through the somatosensory control technology, users simply move the Air mouse, you can operate the smart TV screen mouse click. MEMS sensor and sensor fusion algorithm is the basis of wireless, three-dimensional cursor control, this control will bring exciting new TV interaction. Here to introduce What are the key factors in the Air mouse system design?  

1.Air mouse lacks a wired connection

Three-dimensional air operations need to image and into a two-dimensional cursor, the operating system can be displayed on the screen, which in the system caused a problem: delay.

We always want smart TV to quickly understand somatosensory gestures and respond immediately. However, as mentioned above, since data collection is complex and requires transmission and processing to map actions to cursor control, we can not help asking, "How fast can we be?" Our study shows that the motion control system The target delay time should be around 30 to 50 milliseconds. Beyond this limit, even the primary user can feel the delay. Therefore, the development of reasonable delay target value is an important basis for determining the success of the action control system.

2.Air mouse no plane friction

PC mouse placed on the table, you can keep the action through the friction to stabilize, and Air mouse is not such a condition, it will intensify the impact of unintentional action on the cursor control.

The common approach is to use a simple low-pass filter to eliminate all the actions below the input rate of 5 degrees per second. However, this will also affect those who deliberately the slightest action, resulting in the so-called action "dead zone", hinder the user precise selection of small targets, so that the user interface design constraints. So, it is very important to tell which is jitter, what is the intention of the action, and the difference between the two are very important.

In addition, unintentional actions caused by pressing the button should also be identified and eliminated. This can be done by freezing the mouse cursor when the button is pressed, or by performing an action while the button is being released, rather than pressing the button to prevent an unintentional action during the press of the button.

The above is a brief introduction to the key elements of the air mouse design, learn more about the contents of the Air mouse, please pay attention to kepnixshop official website.
