The currently available model relies on sensors to detect obstacles and warns the wearer via vibration and an alert sounded on a Bluetooth-linked smartphone. “Sensors on the toe of the shoe detect obstacles up to four meters away. The wearer is then warned by vibration and/or acoustic(听觉的)signals. This works very well and is already a great help to me personally,” Markus Raffer, one of the founders of Tec-Innovation, himself visually damaged, said.  That sounds impressive enough, but the company is already working on a much more advanced version that combines cameras and artificial intelligence to not only detect obstacles but also their nature. “Not only is the warning that I am facing an obstacle relevant, but also the information about what kind of obstacle I am facing. Because it makes a big difference whether it’s a wall, a car or a staircase,” Raffer claimed.

答案：

这部分内容主要考察的是宾语从句的知识点：

名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。

置于动词、介词等词性后面起宾语作用的从句是宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式、动词现在分词、过去式、过去分词后面都能带宾语从句。有些形容词（afraid,sure,glad等）之后也可以带宾语从句。

宾语从句可以作及物动词、介词及形容词的宾语。宾语从句的语序一律用陈述句语序。连接词that引导宾语从句在句中无词义，不充当句子成分，口语中一般可以省略。

whether 和 if 都可引导宾语从句，但 whether后可紧跟or not；whether从句可作介词的宾语。当if/whether引导宾语从句时，在从句中不做任何成分，但有具体的含义，意为“是否”。if/whether不能省略。
