Orca is a special tool that helps people who have difficulties seeing or using a computer. It is like having a special helper who can read the computer screen for you and tell you what is happening.
Orca can help you in many ways like reading text, magnifying the screen, describing icons and images, and even helping you navigate through web pages. It helps people with visual impairment or those who cannot use a mouse, keyboard or touch screen by providing a voice over and keys to operate the computer.
Imagine you're trying to read a storybook but you cannot see well or you're not able to read it by yourself. Orca is like the person who can read the book to you and describe the pictures in the book. It is a very helpful tool that makes computers accessible to everyone!
