Why is Hawking's chair valuable?

On the morning of March 14, local time in Britain, Stephen Hawking, one of the best physicists in modern times, died at the age of 76. Although he was paralyzed by gradual freezing and could not speak, all this failed to destroy Hawking's clever brain and humorous soul. 1963, 2 1 year-old Hawking was unfortunately diagnosed with amyotrophic lateral sclerosis, that is, motor neurocytopathy. As his condition continued to deteriorate, Hawking was almost paralyzed and unable to speak. He can only sit in a wheelchair and communicate with others through a few fingers, eyes and facial muscles.

Everyone should have the necessary software, the strongest and most stable activation weapon!

The company that provides customized lifting wheelchairs for Hawking is the famous American Intel Company. It turns out that the lifting wheelchair is a black technology product. It is reported that as early as 2006, Intel submitted a patent application for Hawking's innovative technology of customizing wheelchairs.

For example, Hawking uses facial muscles and a movable finger to find the words he wants, and then transforms the words into actions to end his speech. But the deterioration of Hawking's health before his death also means that this process is getting slower and slower. Two years before Hawking's death, some media reported that Hawking could not spell a word in one minute.

When AI meets cloud accounting, is AI a god or a demon?

It can be said that this wheelchair is a product that integrates a series of technologies, such as a detector that receives signals from infrared emitters and detects muscle activity. Through it, Hawking's thoughts can be transformed into sounds and words and expressed to the whole world.

Hawking only needs to twitch his facial muscles subtly when typing.

It can be seen that Hawking's wheelchair equipment is a super powerful artificial intelligence machine. This almost unique wheelchair in the world is not only a means of transportation for Hawking, but also a part of Hawking's personal image. In addition to a tablet computer that can be seen at a glance, it is also an artificial intelligence device that integrates computer software, communication technology, infrared ray and voice converter.

For example, the tablet computer in Hawking's wheelchair has a Core i7 processor, which can control all the electronic systems in the wheelchair. Wheelchairs are equipped with a device called a peripheral box, which contains a USB hub, an audio amplifier and a rectifier for various subsystems. They are controlled by infrared sensors on Hawking glasses and can respond to light changes caused by facial movements.

As shown in the above picture, Hawking's lift chair is determined by a sensor, which is applied to all parts of the chair. The information monitored by the sensor, such as Hawking's activities and the help that the wheelchair can provide to Hawking, can also be conveyed through the Internet. Hawking can use the control buttons on the control device together to control the wheelchair by driving the preset rules. This wheelchair integrates sensors, computers, controllers, Internet communication, control programming, voice communication, data processing and many other artificial intelligence technologies.

Through the super-active sensor, this system can monitor many facial expression changes of Hawking. In addition, the speech synthesizer has been promoted and transformed by Intel. By improving the guessing ability of the writing system, Hawking can spell 5 to 10 words in one minute.

Of course, Intel's black technology patent is not just Hawking's patent, and all those in need may benefit from it.

With the help of modern cutting-edge technology, Hawking, trapped in a one-square-inch wheelchair, can convey his profound thoughts to thousands of people who are curious about the world in Qian Qian. As far as you and I are concerned, the greatest inspiration brought by this legendary physicist may be to remind people to remember to look down at the starry sky occasionally from the slim and trivial days and never throw it away. Say hello to Hawking!

Mobile radio and television work together, and the future is promising.

This control method is similar to the distance sensor on a smart phone. The sensor emits an invisible infrared beam and detects the distance according to the intensity of reflection of the policy object. Hawking shortens facial muscles, and the sensor receives the modified signal, and then feeds back a confession to the computer. This method can completely replace the previous manual click operation without changing the original operation logic.
