Smart surfaces – a revolution in the car-human interface

Smart surfaces/functional surfaces/shytech surfaces

car manufacturers today need to bring increasing functional complexity in the car interior into lean design, while at the same time allowing greater flexibility to enable over-the-air (OTA) updates of the so-called ‘smartphone on wheels.’ For that reason, display areas are expanding, while the user experience, complexity, cost and weight of interfaces based on physical buttons, knobs and rotary switches seem ever more outdated. However, displays are limited to certain surfaces. They suffer from reflections, do not allow freeform geometries, and the cost is not optimal for areas with a dedicated set of functions.
So, a new HMI – so-called smart surfaces – is revolutionizing interaction in middle console, center stack, overhead consoles or door panels. Shytech buttons and interactive, decorative backside illuminated animations can appear when the user looks at it or moves their hand nearby. Three-dimensional surfaces allow blind controllability where taking the eyes off the street would be too dangerous.

ams OSRAM offering

ams OSRAM offers a broad portfolio of solutions for smart surfaces from emitters to sensors and drivers. Our LEDs can be used for surface integrated ambient lighting, light-guide applications or button backlighting. We offer optical sensors for example for automated brightness control, but also non-optical sensors (inductive, magnetic, or capacitive) that can be used for example for the seamless integration of rotary-push buttons on smart surfaces. IR emitters and detectors are used for simple gestures and proximity.

Open System Protocol (OSP)

As ambient lighting and touch interfaces merge in the same surfaces, also a combination on system architecture level is possible.​

ams OSRAM supports this trend in the Open System protocol ecosystem with own components (like intelligent RGB modules). Also the integration of sensors or haptic feedback devices can be done using the stand alone intelligent driver (SAID) ​

OSRAM OSIRE® E3731i, KRTBI D2LM31.31

OSRAM OSIRE® E3731i, KRTBI D2LM31.31

This device is especially designed for automotive interior applications requesting high dynamic RGB lighting scenarios. This device is an intelligent RGB device, incorporating besides R/G/B LEDs an IC from ams OSRAM. This embedded IC integrates the drivers for the three R/G/B LEDs. The embedded IC includes the optical measurement data of the three R/G/B LEDs as well. An external micro controller can address and control each device in a daisy chain architecture via an open system protocol. The open protocol allows the micro controller to read back these data and to run any color algorithm. It also allows to read back a temperature value to optimize this color algorithm.

ams AS8579 Capacitive Sensor

ams AS8579 Capacitive Sensor

The AS8579 is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the impedance that originates between a conducting surface (metallic object) and a human being. The IC captures the current of a metal object and applies algorithms to determine the capacitive and resistive information. The outcome information can be read through a SPI Interface that can be also used for IC configuration. This high precision performance sensor also supports a multitude of diagnostic features that meet standard functional safety requirements. The capacitive sensing IC is specifically designed to function in an electro-magnetic environment (EMC) with high magnetic disturbances. This allows the sensor to distinguish in a hands-on application if the driver‘s hand is on the steering wheel or not. The AS8579 is available in an SSOP24 package and operates at a supply voltage of 5V.
