VERIFICATION OF SYMBOLS RECEIVED THROUGH A TOUCHPAD OF A REMOTE CONTROL DEVICE IN AN ELECTRONIC SYSTEM TO ALLOW ACCESS TO SYSTEM FUNCTIONS

摘要

An electronic system comprises an electronic device and an associated remote control device having a touchpad. The electronic system receives verification data that corresponds to a first user input of a verification symbol. The electronic system receives a second user input through the touchpad, and in response, generates user data that corresponds to the second user input. The electronic system compares the verification data to the user data to determine if a matching relationship exists between the verification data and the user data. The electronic system provides access to a function if the matching relationship exists, and denies access to the function if the matching relationship does not exist. In some examples, the electronic system receives the first user input of the verification symbol through the touchpad, and in response, generates the verification data that corresponds to the first user input. In some examples, the electronic system is a video system.
