Patent number: 11955245Abstract: A method and a system for mental index prediction are provided. The method includes the following steps. A plurality of images of a subject person are obtained. A plurality of emotion tags of the subject person in the images are analyzed. A plurality of integrated emotion tags in a plurality of predetermined time periods are calculated according to the emotion tags respectively corresponding to the images. A plurality of preferred features are determined according to the integrated emotion tags. A mental index prediction model is established according to the preferred features to predict a mental index according to the emotional index prediction model.Type: GrantFiled: July 2, 2021Date of Patent: April 9, 2024Assignees: Acer Incorporated, National Yang Ming Chiao Tung UniversityInventors: Chun-Hsien Li, Szu-Chieh Wang, Andy Ho, Liang-Kung Chen, Jun-Hong Chen, Li-Ning Peng, Tsung-Han Yang, Yun-Hsuan Chan, Tsung-Hsien Tsai

Publication number: 20210315473Abstract: A method for analyzing an electrocardiography (ECG) signal is provided. The ECG signal is measured through a sensor. One or more specified waveforms in the ECG signal are detected. Multiple ECG features from each specified waveform are captured. The ECG features are input into multiple candidate models to obtain multiple candidate scores. Each candidate score is compared with a standard value to obtain an ideal score among the candidate scores. One of the candidate models corresponding to the ideal score is selected as a risk prediction model to predict disease risk through the risk prediction model.Type: ApplicationFiled: May 13, 2020Publication date: October 14, 2021Applicants: Acer Incorporated, National Yang-Ming UniversityInventors: Yun-Hsuan Chan, Ke-Han Pan, Wei-Ju Li, Liang-Kung Chen, Li-Ning Peng
