Interactive Infrared LED Enables Gesture Control In Car Interiors

The device comes in a compact, infrared LED (IRED), which can be used for gesture recognition to control and communicate intuitively

In the coming years, autonomous driving will require cars to be equipped with more interactive functions that will make communication between occupants and vehicles more intuitive. Since they will have a different interior design as compared to the current cars, the classic dashboard will be replaced by other user interfaces and options for communication. Today, drivers can use voice assistance for navigation and control simple functions via gesture control.

Facilitating this dramatic change is the Oslon Piccolo, which offers an extremely compact infrared LED (IRED) that packs enormous power in a small package.

Thanks to gesture recognition, completely new ways of using displays have been created. For example, when navigating to a destination, the vehicle displays a map with the corresponding route. At the edges of the image, different menu items for operating the display are often shown in a standardised way – which in turn takes away space from displaying the map. With the help of gesture recognition, menu items are only shown when the driver moves their hand towards the display, allowing the route to appear in full screen.

“The advantages of the Oslon Piccolo really pay off when used in conjunction with indoor displays,” explains Walter Rothmund, Marketing Manager for Sensing at Osram Opto Semiconductors. “Thanks to its extremely compact dimensions of only 1.6 mm x 1.6 mm and a package height of only 0.81 mm, the IRED can be installed easily in a small space.” 

With a DC power of 1.15 W at 1 A and very fast switching times of 10 ns, the component is suitable as both a constant light source for a camera-based application and 3D image acquisition with modulated or fast pulsed light. The automotive-qualified component (AEC-Q102) is available in two different wavelengths: 850 nm (SFH 4170S A01) and 940 nm (SFH 4180S A01). They can be immediately obtained from OSRAM.
