Desks are one of the most basic office equipment. In order to meet the requirements of modern office environments, the current office table further has the functions of electric lifting, table top splicing, peripheral control and the like, and therefore interactive control becomes an integral important component of the office table. At present, an interactive control module of an office table only realizes a single function generally, and most of interactive modes adopt entity keys. Taking the most commonly used electric lifting table as an example, the control module is only used for controlling the lifting motor, and the physical keys are attached to the upper surface or the side surface of the table top. The control module does not have expansibility, and the desk is required to be provided with a key opening in appearance, so that the operation position is relatively fixed.
Gesture control is one of mainstream somatosensory technologies, and a more natural and convenient interaction mode can be provided, so that the defects of entity keys can be effectively overcome. On the other hand, due to the diversity of gesture control, a foundation is provided for the function expansion of the control module. The module can not be limited to the control to the desk body, also can connect other electronic office equipment as interactive terminal, realizes on this basis that control module's integration, function module ization and programability, further expands the additional function of desk, provides more facilities for the staff.
The existing office desktop control module has single function, mostly only supports desktop height adjustment, and has no expansibility. Some have incomplete system architecture and low modularization degree. In the interactive mode, the use of the entity keys requires the reservation of key positions, which may damage the overall appearance. The desktop pressure resistance of the touch screen device is reduced, and the surface is easily abraded. Although some systems adopt gesture control, the functions are fixed and cannot be expanded due to the limitation of the control module.
