Through the story of the article, I have a general image understanding and usage of PDA and brainpal. Here is a sketch of my PDA and brainpal.
I think a PDA is like a mobile phone or a tablet. It is an electronic product that can be carried around with a pen. I think its functions are very similar to that of a mobile phone, navigation, alarm clock, touch screen, etc. But the functions seem to be less than that of mobile phones, but at the same time, some spatial functions are not based on electronic products. People control the PDA by tapping, touching the screen, and doing other interactive actions. But I don’t think a PDA is a very good idea, because I don’t think it’s any different from the now-completely functional phones and tablets.
The article about brainpal does not describe much about its shape. It is similar to a product that exists in people’s brains and can be controlled by the thoughts in their minds, but because I think a carrier is needed, I draw a carrier similar to glasses. . As for controlling brainpal, it seems that you only need to control it with your thoughts. This is a very simple and convenient usage, and then you can directly hear its voice or see some information directly in the air through the control in your mind. Now some similar products such as AR or VR are to see different 3D worlds by wearing glasses. I believe that the idea of brainpal is an imagination of many people for future technology, and I am very much looking forward to the emergence of such a product.
