摘要:
A key determination method for a metal key. The method comprises a step of determining whether values output by an electrical parameter converter on a metal key satisfy multiple levels of thresholds, and, a step of setting a press flag of the metal key according to multiple levels of thresholds; and after the metal key is released, determining whether a release flag is valid according to a press model, and if so, clearing the press flag that was previously set. Different press models and different thresholds are selected and configured by means of software, so that personalized choices are provided for respective metal keys, which effectively facilitates different operators in configuring a metal keyboard according to usage habits, thereby improving the operating efficiency. In addition, the setting of different thresholds effectively protects the operational details mean for the exclusive use of operators, thereby achieving the required confidentiality.
