123. The console can determine how the controller is moving in space and what it is pointing at, and uses that information to control what is happening on screen.

【结构分析】

1、以逗号后and为切入点，得到主句部分的并列平行结构The console can determine…, and uses that information to control…，uses与can determine一起作该句的谓语。

2、其中determine的宾语也以and切入，得到how引导的名词性从句how the controller is moving in space和what引导的名词性从句what it is pointing at(how在从句中作状语，what在从句中作宾语)；在use的宾语补足语to control…中，control的宾语使用了what引导的名词性从句what is happening on screen充当，what在从句中作主语。
