With the world on the path of adapting to autonomous vehicles, in-vehicle assistants are a must in the present cars. The AI powered in-vehicle personal assistant play an important role in the future as the experience will be more aligned towards infotainment and work rather than vehicle operations.
The AI driven automotive technology is changing the way we are interacting with our cars. The new technology has the ability to convey about the real-time happenings that are taking place in your surroundings, right from the updates you need on route till you reach your destination.
For example, with the indirect voice control in place, the occupant can give a cue that he’s feeling cold and eventually the temperature controls will adjust according to the likes of the occupant. Same is the case with infotainment as well. If the occupant says, “Reduce the volume,” the sound controls will adjust the volume according to the likes of the occupant.
Gesture Recognition & Touchless Controls
Recent advancements have introduced gesture recognition technologies to the automotive HMI domain. Through the use of depth-sensing cameras and machine vision algorithms, vehicles can now detect and interpret hand movements and gestures made by the driver. This enables touchless control of various functions, such as adjusting volume, answering calls, or accessing infotainment menus. BY reducing the need for physical touch, gesture recognition enhances user convenience and reduces distractions, particularly during critical driving moments.
