From the gesture recognition technology to see the integrated interconnection system of the mainland
Gesture recognition is not new, but the gesture recognition installed on the steering wheel, have you seen it?
This article refers to the address: http://
Since the release of a Holistic Connectivity demonstration car at CES in the United States, the mainland began to add some new features to the system to slowly improve it. Recently, the mainland has released a new set of gesture control technology. However, unlike the gesture control technology we have seen before about Volkswagen, Delphi, and Visteon, the mainland's solution is based on the steering wheel rather than the center console.
Continental gesture recognition technology
How to recognize gesture recognition on the steering wheel?
This gesture recognition technology is a new member of the mainland's holistic human-machine interface. On the gesture control demo picture released on the mainland, there is a transparent plastic plate on the left and right of the steering wheel. Use the thumb to swipe, tap and double-click on the plastic plate. The display on the front digital dashboard will be based on the gesture. Different display different functions. From the introduction and the above picture, this does not seem to be gesture control, but should belong to the touch range. Previously, Mercedes-Benz also showed a touchpad mounted on the steering wheel, which can control the corresponding functions of the vehicle.

actually not. In this technology of the mainland, the two transparent plastic plates are only plastic plates, which do not have any electronic components and are not connected to the electronic system on the vehicle. Here, what really works is the ToF camera mounted on the dashboard, which contains a 3D camera and image sensor that emits infrared light to detect changes in the driver's gestures and converts the detected infrared signals into 3D images. Identification of specific actions.
The reason why the ToF camera is to be installed on the dashboard without selecting the roof control area or the central armrest, the mainland said, is to reduce the driver's attention. In the mainland's view, if you want to put your hand near the central armrest to control the central control panel, it will also distract the driver's attention. Set on the steering wheel, the corresponding control function is placed on the dashboard for display, which will reduce this dispersion.
In order to achieve this goal, all the set gestures are based on the principle of "letting the driver's hands not leave the steering wheel". In the currently set gestures, in addition to the strokes, taps, and double-clicks of the thumb, there are also wave-handling actions. The wave-handling action does not require the palm to leave the steering wheel, and only needs to be swung. The function of the up and down gestures currently corresponds to answering or hanging up the phone.

Since the gesture recognition is a ToF camera, what is the purpose of adding two transparent plastic plates? In fact, it is to simulate the manipulation on a smartphone or other smart device. For gesture recognition technology, remembering gestures requires a certain cost of learning. Even if it is as simple as adjusting the volume, the way people take it is different. Some use the palm to move down, and some will be set to clockwise or Circle the circle counterclockwise.
The mainland hopes to reduce this learning cost. When manipulating, the swipe and stroke of the thumb are done on a plastic plate. These two plastic panels act like a touchpad, which is relatively familiar to the driver. In addition, when defining the function of gestures, the mainland is also simulating the operation on the smartphone: swipe to browse the menu, click to confirm, and open a program is double-click.
One-piece interconnected service thinking
From the point of view of technical realization, the mainland is no different from Delphi, Visteon, and Volkswagen. The ToF camera is also used to identify gestures. The difference lies in the specific interaction and function implementation.
The dashboard display is different from the central control panel and does not display all the functions. Instead, it prioritizes the relatively important information during the driving process, so the functions that need to be controlled are relatively reduced. Therefore, if you want to adopt this interactive method, you need to consider which functions are integrated into the dashboard for the driver to control. The introduction of the solution requires not only technical factors but also user experience.
At present, there are more and more human-computer interaction methods used in automobiles, and the advantages and disadvantages of touch, speech recognition and gesture control are difficult to compare from the same dimension. Because of careful consideration, which control scenarios are these adaptation methods applicable to? Controlling the opening of the sunroof or window glass by hand does not save too many steps compared to button or voice control, but it does bring convenience.
When introducing the technology, the mainland said that there are not many features that can be controlled at present. There are only four items: answering or hanging up the phone, browsing the App menu, opening music, and setting navigation. Those who have chosen these features are not the mainland, but the users who participated in the technical testing in the early stage. Behind this, what is reflected is the change in identity of the mainland when it introduces new technologies.
Continental integrated internet demonstration car
At CES Asia at the beginning of the month, Car Clouds experienced the integrated integrated display car on the mainland. The car's display function is not just the vehicle's in-vehicle operating system, or the interconnection with the mobile phone, but an integrated solution for the "car scene", including travel, smart home, car sharing and other dimensions. At that time, Wen Yingjun, China's director of body electronics solutions interviewed by Che Yunyun, also said that the mainland is transforming into a system service provider. When designing an all-in-one interconnected demonstration car, the mainland regards it as a smart device.
In fact, the entire automotive industry is moving towards the transformation of travel services. In the car industry, there is Ford in the front and ABB in the back. Under this transformation, Wen Yingjun believes that the relationship between the host manufacturer and the supplier is also changing, from a pure supply and demand relationship to a cooperative relationship. Tier 1 suppliers are gradually becoming service integrators.
Seeing this trend is not only for car companies and Tier 1 suppliers. Tier 1's identity has advantages in integration and integration. After they join the battle, this game about "service" will become more and more. The more meaning.
