The invention relates to a perceptual input keyboard based on a force mode, and belongs to the technical field of human-computer interaction equipment. The input keyboard includes keys, a keyboard scanning circuit film, a circuit board and a bottom plate, an upper electrode film, a pressure sensitive element and a first flexible substrate. The diaphragm of the keyboard scanning circuit is connected to the circuit board. A flexible substrate is provided with grooves and lead-out electrodes, and the lead-out electrodes are connected to the circuit board. The pressure sensitive element is embedded in the groove, the key is installed on the rubber cap, and the rubber cap is linked with the pressure sensitive element through the diaphragm of the keyboard scanning circuit and the diaphragm of the upper electrode. The upper electrode diaphragm is provided with a printed circuit and a lead-out electrode, the pressure-sensitive element is connected to each other through the printed circuit, and the lead-out electrode and the circuit board are connected to each other. The input keyboard of the present invention has high force response speed, is suitable for sensing rapidly changing force, has simple package form, low processing difficulty, and is easy for productization and mass production of equipment.
Description
technical field [0001] The invention relates to a perceptual input keyboard based on a force mode, and belongs to the technical field of human-computer interaction equipment. Background technique [0002] The keyboard is the most basic input device of a computer, and it is a basic binary information input device. Its basic structure is a switch array, and the switch action and its position signal are obtained by scanning the key code. It is most widely used in various fields of human-computer interaction. However, for decades, except for slight changes in appearance and structure, keyboard input devices have not undergone major development and changes all the time. In particular, this kind of input device cannot perceive the application of the force of the operation action, and cannot distinguish the emotion behind the action of the operator. Today, with the rapid development of computer and network technology, and the rapid increase in the speed and quantity of informati...
