At this time, we use the coordinate system of latitude and longitude of the earth. In fact, if it is regarded as two points, because there is still height, another description is needed, for example, one person is on the street, and the other person is standing on the top of a dozen-story building. If we look at the latitude and longitude of the map, we say that this person is due south executive email list of the other person. Obviously this description is incorrect, we generally say that this person is above another person. The relative position includes the relative position of the user and the medium, executive email list the relative position of the information transmitter and receiver of the user and the medium (the user's information receiver, which you can temporarily understand as the eyes, receives external information.
The user's information The transmitter, which you can understand as our hands, operates.) Relative position of user and medium: The main point here is that during executive email list use, the relative positions of users and media may change constantly. During this period, we have to consider whether the information exchange between people and products is still smooth. For example, when we use the washing machine, we will definitely not squat in front of the washing machine executive email list and wait for the clothes to be washed. After turning on the switch, we will be busy with our own affairs, watching dramas in the living room or something.
At this time, how the washing machine communicates with people can only be through sound, because the information of the sound can also be transmitted to people's ears, but if the washing machine only has the completed indicator light flashing, then because there is a executive email list wall between the washing machine and the person, people cannot received this information. The relative positions of the respective information senders and receivers of the user and the medium: The main point here is that in the process of use, these information receivers and transmitters will affect executive email list each other. For example, when typing on a mobile phone, if you want to insert a sentence in the middle of this word, you need to put the cursor in the input box. Navigate to where you want to type.
