在旅游时,我发现导游要多次清点游客人数,就想发明一种检测旅游车车上人数的装置。近红外光电辨向探测器线路多,不方便固定在旅游车里,采用哪种检测装置成为关键。妈妈新买了智能手机,用手指轻松滑动手机屏幕,完成多种功能,太神奇了!我的手机是按键操作的,爸爸的手机是用笔触屏的,差别在哪里?查询得知,爸爸的手机是电阻屏,妈妈的手机是电容屏。

When I was traveling, I found that tour guides had to count tourists many times and wanted to find a device to detect the number of people traveling in coaches. Near-infrared photoelectric detector line direction, inconvenient fixed in the coach, which testing device used as the key. My mother bought a new smart phone, easy to slide your phone screen with your fingers to complete a variety of functions, amazing! My phone is a key operation, my father’s cell phone is a pen touch screen, the difference? Inquiries, my father’s Cell phone is a resistive screen, mom’s cell phone is a capacitive screen.
