The loop mode of the music player: single loop, sequence play, random play, the cooking mode of the induction cooker: grill mode, steam mode, soup mode. Summary: The analysis of the characteristics of the function is over here, and the next thing to do is executive email list the analysis of the characteristics of the information receiver and the information transmitter. Information receivers and information senders Thinking Session: Let's go back to the example of turning executive email list on the light, my desk lamp has the function of controlling the brightness and controlling the color temperature. Luminance is a single-bounded dimension, with a luminance of 0, and the unit describing luminance is lumens.
Then the maximum brightness of this table lamp will definitely not be brighter than the playground lighting. Brightness will max out at a certain lumen. Assuming that executive email list my desk lamp has a maximum brightness of 1000 lumens, what should I use to control the brightness of 0 to 1000? Can you use the knob? Assuming that it is controlled by one knob, and the precision is 1, the knob has to be divided into 1000 parts. Can this knob be designed to be as small as executive email list the knob of an ordinary watch? If such high precision is not required, the 1000 copies here are actually artificially identified. If there is a need to be accurate to 0.1, it will be divided into 10,000 copies. What to do now? Controlled with a super-large knob? How about precise control without such a big knob?
If this light also controls the color, do I need to add another knob to control it? Or is it possible to control both dimensions simultaneously with one receiver? To executive email list answer the above questions, you need to understand the relevant content of information receivers and information transmitters. After you read this chapter, look back and think about the above questions yourself. If you can think about the answer, you have already learned it. Characteristics of message receivers and message senders Information receivers and information transmitters have executive email list three characteristics: boundary, dimensionality, and directionality. 1. Boundary between information receivers and information senders The medium will be controlled in a certain space size. If it is too large, it cannot be operated, and the range of hand movement is large. It's like the mobile phone screen is getting bigger and bigger, but no matter how big it is, it will not be bigger than the iPad.
