What is a Mobile Smartphone?
A smart phone is like a personal computer. It has an independent operating system and independent running space. Users can install programs provided by third-party service providers such as software, games, navigation, etc., and can implement wireless networks through mobile communication networks. The general name of the type of mobile phone connected.
- The world's first recognized smartphone, the IBM Simon (Simon Personal Communication Device), was born in 1993. It was manufactured in collaboration with BellSouth. As an emerging technology,
- Features of smart phones:
- In a broad sense, in addition to the phone's call capabilities
- Global smartphone market share
- With the popularization of smartphones, thumbs type and WeChat, and index and middle fingers swipe across the screen, which may be the most frequent "activity" of many people every day. A new Swiss study says that regular smartphone use leaves a strong "imprint" on the part of the brain that handles touch.
- The researchers performed 1,250 stimuli on the thumb, index and middle fingers of 26 touch-screen mobile phone users and 11 traditional mobile phone users, and recorded their EEG, and then compared the test results with the mobile phone usage records in the past 10 days. .
- The results show that compared with users who do not use touch-screen technology, smartphone users' somatosensory-related cerebral cortex activity is enhanced, that is, the activity of processing finger touch brain regions is enhanced.
- The head of the study, Alk Gorsch, said that the more frequently a smartphone is used, the more intense the somatosensory cortex of the brain, and this frequent touch may eventually reshape the way the brain directs fingers to work. What kind of impact this change has on humans, Gao Xi said, may not be all good news. If there is evidence that excessive use of smartphones may be related to motor dysfunction and chronic pain. Some researchers also believe that frequent use of smartphones may cause problems such as memory loss and inattention. [6]
