Voice Control Vs. Air Interaction, Which Contactless Elevator Is Better?
During the COVID-19 outbreak, many technology companies have used the power of technology to contribute to epidemic prevention and control. Contactless elevator buttons have also become popular online and have become a new favorite in hospitals, office buildings and other places.
Since the outbreak of the epidemic, avoiding cross-infection has always been the top priority of prevention and control work.
As a narrow and confined public tool with a large flow of people, elevators naturally become a high-risk hidden danger of cross-infection. As the general public "fights wits and courage" with the virus, various "artifacts" such as plastic wrap and toothpicks have appeared in elevators.
Some time ago, AISpeech launched a voice-controlled elevator, which allows users to control the operation of the elevator through voice commands.Elevator buttons become a dangerous area? Try using voice control.
Recently, an air elevator button appeared in Hefei, Anhui, bringing scenes from science fiction movies to our side.
Click in the air, science fiction becomes reality
March 2,The first air imaging contactless elevator button terminal was officially put into use in Hefei High-tech Zone, Anhui Province.The sci-fi scenes sparked heated discussions.
It is said that this is the world's first air imaging contactless elevator button terminal
It is reported that the deviceUsing air imaging technology, users only need to "click" the screen in the air to reach the destination floor.This avoids cross-infection of viruses caused by touching the buttons.
The appearance of this device is very similar to glass, and its working principle can be simply understood as follows:The button image is reflected in the air at a symmetrical position through glass. Combined with certain interactive devices, users can operate the image in the air without the need for real media.
In the elevator, a terminal product will be loaded and connected with the original system of the elevator, and the operation response time is less than 30ms.
It is understood that the terminal was built by Anhui Dongchao Technology Co., Ltd. in Hefei High-tech Zone. The company focuses on precision optical technology for research and development.
The "Air Imaging" elevator button terminal launched this time uses independent patented technology, and the core optical display module of the equipment adoptsEquivalent negative refractive index optical plate lens (DCT-plate) technology.This technology is achieved throughLight field reconstruction principle,The divergent light rays are re-converged in the air to form a real image that does not require a medium to carry it, and combined with a somatosensory interactive device, direct interaction between people and the real image is achieved.
In terms of price, the equipment supplier stated that the current unified selling price for a single product is around 15,000 yuan.
Currently, Hefei's High-tech Zone Management Committee, Anhui Investment Building, and Anhui Provincial Hospital all have pilot projects. The next step may be to pilot projects in other places such as Hangzhou and Beijing.
Voice control vs air imaging, which one is the most powerful elevator?
Both solutions provide great convenience for epidemic prevention and control, but what are the differences between them? We compared these two elevator button terminal solutions in various aspects:
| Compare Projects | Voice-controlled elevator | Air Elevator |
| Ease of operation | Some brands require specific voice wake-up, such as the AIS voice-controlled elevator, which needs to be woken up using the "Xiaomei Xiaomei" voice command. | No need to wake up, just tap in the air |
| Accuracy | AISpeech voice control: speech recognition rate>95%; can recognize Mandarin, dialects, and foreign languages | No data yet |
| Response speed | Completely offline speech recognition, no network required, zero response delay | Millisecond latency, response time less than 30 milliseconds |
| Renovation time | The transformation of elevators is divided into pre-installation and post-installation. Post-installation only requires changes to the human-machine interaction module, which is more time-saving; pre-installation takes 1 day or more. | The transformation process is simple and can be completed within 1 hour |
| Renovation price | The cost of voice control equipment is about 4,000 yuan. With mass production, the cost is expected to drop to about 1,000 yuan in the future. | The price of a single product is 15,000 yuan |
| Privacy and security | Leaking sound privacy | The device can protect the user interface from the viewing angle to prevent peeping |
From this point of view, voice-controlled and air-imaging elevators each have their own advantages and disadvantages. Which one do you think is the "best elevator"?
Regardless of the solution,The current technological transformation of elevators is based on the special circumstances of the epidemic and caters to current needs.As an elevator is a time-saving, mechanized means of transportation, the direct clicking method is the most realistic and convenient.
It seems that the current epidemic situation seems to provide an opportunity for the implementation of these technologies. However, it is also through this opportunity that we can seeIt is the rapid development and maturity of technology in recent years that has made it possible to achieve contactless operation in such a short time.
Although the epidemic is only temporary, these two solutions can still be applied in other scenarios, such as smart home, space management, etc. Contactless operation may be one of the future trends.
