Description
Technical Field
The present invention relates to the field of multimedia playing technologies, and in particular, to a control method and apparatus for a multimedia playing device, and a computer storage medium.
Background
Blind people refer to people with visual impairment. Visually impaired people are divided into two categories, one is blindness or total blindness (i.e., blind person), and the other is amblyopia (60% below normal vision). People with such visual impairment are very popular in life, and because of their visual impairment, many normal people in life are difficult to do.
In the life of normal people, watching television is a very common thing, but people with visual impairment can only listen to the sound in the television for fun, and even more difficult, due to the visual impairment, the people cannot identify various function keys on the remote controller, so that the television station can be exchanged only by the assistance of relatives and friends when the remote controller is normally used, and the television station is very inconvenient to watch television. At present, in order to solve the problem that the blind people are difficult to operate and control the television, a mode of adding blind spots for the blind people to recognize or receiving voice control instructions on a remote controller is mainly adopted.
However, the existing smart television not only provides rich movie and television plays and other related program resources, but also provides some music and audio books and the like. When people with visual impairment watch videos or listen to audio files by using the existing smart television, assistance of relatives and friends is still needed to complete program selection, for example: after the television drama "shoot carve hero biography" is repeatedly copied, when a user sends a voice control instruction "watch the television drama shoot carve hero biography", the smart television often lists a plurality of versions for selection, and people with visual impairment still need assistance of relatives and friends to finish final selection.
