Known as InnoMake, the smart shoe may become a possible alternative to the decades-old walking stick that millions of people depend on to get around as safely as possible. 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。
