Innovative HMI system to debut at Embedded World 2021
Candera, a provider of HMI design tools, Next System, an expert in customized haptic hardware, and DATA MODUL, a leading partner for display technologies, have been cooperating on the development of an innovative HMI system, supporting intuitive touch feedback technology. Featuring different use cases in application fields like industry, nautics, medicine and many more, the system also includes a haptic pin pad, that supports person with visual impairment.
Following several studies on the hierarchy of human senses, touch is often named as one of the most important ones after visual and auditory impulses. Therefore, it is not surprising, that not only our physical but also the artificial world can be enriched from an enhanced input of touch stimuli. The incorporation of haptics and touch feedback technology into displays and touch screens is no future trend, it has already found its way into many application fields like automotive, industry or medicine. Adding these intuitive operating concepts to static devices transforms standard user interface (UI) systems into immersive and living HMI experiences.
Based on these insights, Candera GmbH, Next System, and DATA MODUL merged their expertise in order to create a modern Multi-Scene-HMI system with intuitive and haptic touchscreen support. The result is a highly perceptive UI that combines the best out of 2 worlds – perfect HMI design and enhanced haptic technologies.
Intuitive touch feedback of displays and devices is no longer a privilege of the automotive industry. It has already found its way into multiple application fields like industry, medicine, entertainment and many more. Thus, the trio have highlighted several different use cases across various industries, among them a 2D/3D excavator UI, a nautic sea map, an ultrasonic control unit, a dynamic cashpoint pin pad and more. Indeed, the pin pad supports persons with visual impairment, enabling them to successfully interact with the UI purely based on the haptic and auditory feedback they receive from the device.
All of these use cases have been created with Candera’s HMI design tool CGI Studio, a highly intuitive and user friendly GUI design software. Thanks to Candera’s powerful render engine, the scenes not only feature pin sharp graphics but also 3D elements and animations. CGI Studio’s automated workflows, like the ready-to use controls, integrated state machines, but especially the Smart Photoshop Importer have helped to rapidly turn the flood of images and animations linked to these multiple scenes into living HMIs – and this within only a few weeks instead of months.
Innovative hardware technologies from Next Systems were the perfect match to Candera’s HMI products. As a pioneer in haptic touch, Next Systems set out to create a state-of-the-art haptic touch demonstrator for several applications. The device includes two 10,1-inch touch screens with haptic feedback support based on electrostatic- and piezo-technology. Both screens include force-sense (Force measurement for targeted and safe triggering on the user interface) in order to ensure high quality user experience. The integrated haptic touch technology can be tailormade applied to almost all touch sensitive applications.

“With Candera, as a specialist in HMI UI design, Next System found the perfect partner to realize this very versatile project in a very short time frame,” says Michael Nussbaumer, Product Manager for Display and Haptic Solutions at Next System. “The scenes, screens and functions where quickly created and integrated on the target hardware. Efficient cooperation enabled a quick and cost-efficient execution of the overall project.”
DATA MODUL provided the custom refined cover glass including the latest version of their SITO projective capacitive touch unit. Additionally, the display expert took care of fine tuning touch adjustments and TFT driving.

The new haptic HMI system will be presented virtually for the first time at Embedded World 2021.
