Overview

Description

Human machine interfaces (HMIs) are crucial for providing control and feedback in modern appliances like fridges, ovens, and washing machines. This HMI design is equipped with a haptics-compatible touch panel, voice guidance, and operation controls. It also features odor and temperature/humidity sensors to monitor conditions inside and around the equipment, along with an authentication function using Near Field Communication (NFC) for personal authentication in shared spaces like dormitories or shared housing.

System Benefits​:

  • High-performance HMI design supports haptics-compatible touch panels, voice guidance, and voice recognition for modern and intuitive interfaces.
  • Personal authentication with NFC functionality ensures secure use in shared spaces.
  • Voice guidance and operation controls enhance accessibility for all individuals.
  • High-precision sensing functions for odor and temperature/humidity enable smart features in appliances, such as washing machines and fridges to detect when laundry is clean or if food is spoiling.
