摘要： A multi-touch method includes, in response to at least one finger of a user pointing toward a computer screen, recognizing an eye and at least one finger in an image frame taken by a camera; mapping a first coordinate of the recognized finger in the image frame to a second coordinate of the finger on the computer screen; mapping a third coordinate the recognized eye in the image frame to a fourth coordinate of the eye on the computer screen; determining whether the fourth coordinate is in the proximity of the second coordinate; in response to a positive decision, determining the second coordinate as a multi-touch point.

摘要： A computer receives a first audio signal that is acquired by a first user device used by a first user in a conference and a second audio signal that is acquired by a second user device used by a second user in the conference. The computer processes the first audio signal based on the second audio signal to improve quality of the first audio signal, and sends the processed first audio signal to the conference.
