With the popularity of automobiles, automotive technology is becoming more and more mature, and some innovative in-vehicle technologies have also been developed accordingly. Among them, car gesture sensing technology is one of the most popular car technologies. At present, the world's major car manufacturers are racing to study the car gesture control system, through which the driver can control the car through gestures without distraction. It is believed that this futuristic automotive technology will be available in the next few years.

Many OEMs/parts suppliers develop gesture control technology
At the beginning of this year, Hyundai Motor Co. was equipped with a car audio gesture control system in its concept car, in which the driver can control the volume through gestures. Toyota and Microsoft are also jointly studying this automotive technology. In addition, Volvo Cars is equipped with a related car sensing system for its concept car, which can monitor the driver's line of sight in real time through an infrared camera. When the system senses that the driver's line of sight falls on the vehicle's central control display, the system The on-board central control display will automatically light up.
Correspondingly, the world's major auto parts companies are also conducting research on related products. STMicroelectronics and Melexis are researching such time-axis cameras (infrared cameras). This type of infrared camera works like a radar. It mainly detects changes in moving objects, and it does not produce images from nothing. Such time-axis cameras use modulated infrared LEDs, each of which corresponds to the time point on the time axis. By measuring the time between the start of the light and the reflection, the required distance can be known and then triangulated. The method can obtain the movement trajectory of the measured object.
Visteon Horizon cockpit concept incorporates 3 new technologies
Visteon released the new car cockpit concept on May 15th, demonstrating advanced technologies such as 3-D gesture recognition that are much more futile than people would imagine.
Visteon demonstrated the Horizon cockpit concept to global automakers. The concept transforms the driver's control over the temperature, sound and navigation functions of the car by combining three emerging technologies.
Gesture Control - The advanced camera system copies the virtual hand shape on the central control panel by taking the user's hand movements. As a result, drivers in the Horizon cockpit can easily operate specific vehicle controls simply by moving their hands or even their fingers without touching the dashboard. For example, the volume of the radio can be adjusted by making a rotation with one hand.
Virtual Touch Screen - With a pressure-sensitive touch panel, the driver can operate without having to touch the controls on the central control panel. The touch screen can increase responsiveness by identifying the amount of pressure applied to it. At the same time, the touch screen can be loaded into any soft material such as leather or cloth for operation, maximizing assembly flexibility.
Two-layer display – Information is displayed on two separate but overlapping display surfaces by high-resolution images with emphasis on the information the driver is manipulating. The driver seems to be able to “traverse†the image on the first display and immediately observe what the second display shows.
Visteon combines these technologies with its expertise in human-computer interaction (HMI) to create a unique driving environment for drivers.
“The Horizon cockpit concept demonstrates the potential of combining real-time rendering of 3-D images with advanced display technologies,†said Shadi Mere, Innovation Manager at Visteon. “By combining a number of emerging HMI input technologies, we are able to Create a distinctive cockpit system for an intuitive and enjoyable driving experience."
Before releasing the Horizon cockpit system to automakers, Visteon conducted consumer market research on this concept. 70% of consumers who participated in the show showed a strong interest in using the virtual volume knob in their next new car purchase, and thought it was easier and more convenient to look for a traditional volume knob while driving.
Gesture recognition extended application: "space" wake-up display
When such technology has been extensively studied and achieved great results, another automotive technology has been applied to on-board touch screen control. Most car touch screens automatically go to sleep for a long period of time without operation, and you need to touch the display if you want to wake up the display, but now you don't need direct contact, just put your hand or finger near the touch screen. You can wake up the touch screen. Among them, Cadillac's user experience system and the touch screen equipped with the 2014 Corvi support this kind of nearby wake-up touch screen technology.
In addition, major auto parts companies are researching and developing the wake-up distance limit for nearby wake-up touch screen technology. Among them, the CapSense touch screen sensor developed by Cypress Semiconductor can detect a distance of one foot, so that the driver can use the CapSense touch screen to control the central control display system by gestures up, down or even turning pages. Without distraction.
Traffic Lights are traffic lights that command traffic and are generally made up of red lights,green lights and yellow lights.The red light means no traffic,the green light is allowed to pass,and the yellow light is a warning.
Traffic lights are divided into:light motor vehicles, no-motor vehicles lights,pedestrian signal lights,direction indicator lamp(arrow lights),driveway lights,flashing warning lights,road and rail light plane crossing.
