Avoid stress points in the display

Electronic Displays Center Gundersheim, June 21, 2018. Klaus Wammes, Managing Director of Wammes & Partner GmbH, will give a lecture and participate in a panel discussion on July 12 at XperiCon at the Munich Hilton Park about HMI verification and programmed fault lines in formally specified hardware design. The lecture series provides insights in the Experience Lab about current HMI technologies and showcases news regarding IIoT and Industry 4.0 applications.

Wammes' lecture particularly addresses cross-application practical examples of fault lines in HMI systems. According to the display and optoelectronics expert, HMIs are probably the most widespread class of embedded systems, designed to operate without special requirements in the consumer segment but sometimes under extreme conditions in industrial environments. Since the design of such multi-component HMI systems often specifies environment and device performance through formal criteria, design faults are pre-programmed if compatibility checks between these criteria are omitted.

"Product development is a complex topic that is becoming increasingly complex. The same applies to the relevant rules, standards, and procedures. Aside from the desire for even shorter time-to-market, embedded display systems are no exception. All these frameworks must also consider physics. These cannot be changed or avoided. Achieving the goal 'NTF - No Trouble Found' is therefore a long journey, which increasingly requires additional technical specialists—similar to an architect, doctor, or tax advisor," says Wammes.

It is important not to wait until it is too late to consult these experts. Timely cooperation is crucial to select the most favorable and best option from all available possibilities. However, in case of need, a suitable troubleshooter should also be known and available.

Therefore, at the interdisciplinary HMI-XperiCon, hardware and software sides meet at the application level. Selected keynotes define HMI in the context of IIoT developments and present strategies for long-term resilience amid increasing complexity. Lectures, tutorials, and practical hands-on shows complete the program. The accompanying trade exhibition is integrated into the main lecture hall and offers an experiential space for active participation in hands-on demonstrations such as HMI prototyping, hackathons, and design flow simulations.
