Problems solved by technology

However, today's touch panels can only execute a corresponding single command by detecting the position of the touch, but cannot execute further commands through a one-time touch action, so it cannot satisfy the user's need for more human-computer interaction. The need to communicate intent to electronic devices efficiently and more intuitively
