Multimedia Console as a Touchless Operating Panel – Use Case at “WPRA”

This project showcases the flexibility of the GETT.PROJECTS modular approach, demonstrated through a custom solution developed for a client we refer to as “We Prefer to Remain Anonymous” (WPRA).

As an OEM service provider, confidentiality is often part of our agreements. Many of our clients request project-level privacy and prefer not to be named in marketing communications. The term WPRA is fictional and stands for “We Prefer to Remain Anonymous.”

DESCRIPTION OF THE PROJECT

Client: WPRA

Type of product: multimedia console

Product idea

The multimedia panel was developed as a modern, intelligent, and visually appealing interface featuring six keys, an NFC reader, and a display — all within a modular design concept.

Beyond registering keystrokes and displaying content, the panel is also engineered to detect specific installation configurations and generate switching signals. Additionally, it supports the integration of complete menu navigation as well as control and processing logic, enabling flexible and application-specific functionality.

Sector

The WPRA* client operates within the food industry. However, thanks to its design-forward features, the multimedia console is also ideally suited for use in visually demanding environments — such as point-of-sale settings, interior design applications, or the furniture industry.

The Challenge

Due to the timing of the project during the COVID-19 pandemic, innovative touchless input technology with optical buttons was the preferred solution — offering enhanced hygiene and user safety.
