Patent number: 9063626Abstract: A touch recognition method, a touch key structure and a touch device are provided. The touch recognition method includes when the touch key structure is faced to touching or near touching, supplementing charges to a charge accumulation area corresponding to each key in the touch key structure until the charge amount in the charge accumulation area corresponding to each key reaches a balance; calculating the charge variation amount in each charge accumulation area when the touch key structure is faced to touching according to the charge supplement amount in the charge accumulation area corresponding to each key, and calculating the ratio of the charge variation amount to the charge balance amount in each charge accumulation area; recognizing the key corresponding to the charge accumulation area which has the largest charge variation amount and the largest ratio of the charge variation amount to the charge balance amount as the touched key.Type: GrantFiled: December 1, 2010Date of Patent: June 23, 2015Assignee: Jiangsu Huitong Group Co., LtdInventors: Tao Long, Zhengdong Liu, Jiang Long
