Hello, Options: wood, iron sheets.
Answer: wood.
Parse. On December 9, 1968, Dr. Douglas and his contemporary, Bill Inglis, made the world's first "mouse", in which his shape was made of an all-wood shell.
The world's first mouse was in the shape of a small wooden box, which worked by using the resistance change caused by the mouse movement to achieve the positioning and control of the cursor.
It is also relatively simple in structure, equipped with two perpendicular disc wheels (non-spherical) at the bottom, each wheel drives a mechanical rheostat, and the resistance value of the rheostat will be changed when the mouse moves.
If the applied voltage is fixed, the strength of the electrical signal fed back by the mouse will change, and using this changed feedback signal parameters, the system can calculate its displacement in the horizontal and vertical directions, and then produce a set of dynamic coordinates that change with the movement of the mouse.
This dynamic coordinate determines the position and movement of the mouse on the screen, so it can replace the up, down, left, and right keys of the keyboard, allowing the user to position the cursor in various parts of the screen. Because the tail of the original mouse dragged a data line, it looked like a small mouse, and later people simply called it "mouse", which is the origin of the name "mouse". On December 9, 1968, a patent was applied for its design.
Of course, the primitive mouse does look pretty rudimentary from today's perspective, with an all-wood casing, angular, bulky and bulky, and an additional power supply to work, making it inconvenient to use. Coupled with the use of a large number of mechanical components, the mouse will have very serious wear and tear problems over time.
A mechanical mouse, also known as a scroll wheel mouse, is mainly composed of a rolling ball, a roller column and a grating signal sensor. The mouse is connected to the host computer through the PS 2 port or serial port. There are generally four wires used in the interface, which are power, ground, clock and data. And the optical mouse thoroughly.
The optical mouse does not have the scroll wheel of the mechanical mouse, and the dirt on the desktop is generally not rolled into the inside of the mouse when used, so that the mouse is no longer dirty.
The closed structure of the optical mouse makes the mouse still sensitive and smooth after long-term use, and the life of the mouse is greatly extended.

Wood. On December 9, 1968, the world's first mouse was born at Stanford University in the United States. Its inventor was Dr. Douglas Engelbart.
The shape of this mouse is a small wooden box, and its working principle is that the small ball at the bottom of it drives the pivot to rotate, and then drives the rheostat to change the resistance to generate a displacement signal, and transmits the signal to the host, and the mouse is used to replace the cumbersome instructions of the keyboard from then on, so as to make the operation of the computer more convenient.
The invention of the mouse:
The mouse was invented in 1964 by Douglas Engelbart, who was working at the Stanford Research Institute (SRI), an institution sponsored by Stanford University, and who had long been thinking about how to make computers easier to operate and how to replace the cumbersome instructions entered by the keyboard.
In the early '60s, he took out his laptop (not a laptop) while attending a conference and sketched a device that used two wheels perpendicular to each other at the bottom to track movements, which was the prototype of the mouse. In 1964, Douglas Engelbart perfected the idea of such a device and produced the first finished product. For this reason, Douglas Engelbart is also known as the "father of the mouse".
At that time, there was no name for the "mouse", and the new device was a small wooden box with two scroll wheels inside, but only one button. Its working principle is to drive the shaft to rotate by the roller, and make the rheostat change the resistance value, the change of the resistance value will produce a displacement signal, and the cursor indicating the position on the screen can be moved after being processed by the computer.

1. The shell of the world's first mouse was made of wood.
2. The world's first mouse was made of wood, and the earliest name was "Display System X-Y Position Indicator".
On December 9, Dr. Engelbart of Stanford University in the United States demonstrated the world's first stool sock mouse. The shape of this mouse is a small wooden box, and its working principle is that the small ball at the bottom of it drives the circular pivot to rotate, and then drives the rheostat to change the resistance to generate a displacement signal, and transmits the signal to the host.

1. The shell of the first mouse on the World Circle is made of wood.
2. The world's first mouse was made of wood, and the earliest name was "Display System X-Y Position Indicator".
On December 9, Dr. Engelbart of Stanstoolford University demonstrated the world's first mouse. The shape of this mouse is a small wooden box, and its working principle is that the small ball at the bottom of the jujube branch excites the pivot to rotate, and then drives the rheostat to change the resistance to generate a displacement signal, and transmit the signal to the host.

Ant Manor's daily question on March 16 has been updated, and you can go to answer the question. What was the shell of the world's first mouse made of? Can tears remove toxins from the body?
Do you know the answer? Don't miss it if you don't know yet, a large amount of chicken food is waiting for you to receive.
Ant Manor's latest answer on March 16 was shared.
Question 1: What was the casing of the world's first mouse made of?
Answer: wood.
Analysis: In 1964, people from the Stanford Research Institute abroad developed the first mouse, which was first called the "display system x-y position indicator", which was made of wood, and the outside was like a wooden box.
Question 2: Can tears remove toxins from the body?
Answer: No.
Analysis: The main effect of tears is to discharge unhappy emotions and promote metabolism, usually tears can not discharge the toxins in the body, just a kind of emotional venting, everyone usually wants to cry loudly, holding it is not good for the body,
The above is what is the shell of the world's first mouse made of? Ant Manor's latest answer on March 16 shares all the content, I hope it can help everyone.

1. Cascara sagrada is generally made of ordinary plastic or ABS material, and aluminum alloy and metal are also used. But plastic is generally better than metal.
2. Metal dissipates heat better at room temperature, if you use a mouse in winter, it will be cooler and skinned, and the feel is naturally not as good as plastic.
3. Metals will interfere with and reflect electronic equipment, resulting in signal transmission errors.
4. The memory function of metal or aluminum alloy is not as good as that of plastic, which will lead to pressing the mouse button, and the cost will be too high if titanium alloy is used.
There is also a wave of artificial intelligence in the education sector: the world's first living robot.
