Automotive Human Machine Interface

Nuvoton has designed many highly integrated single-chip solutions that can be used as integrated parts for future automobiles. Although the cost of ISD15D00 / ISD15C00 is low, it is the best audio quality recording and playback device in its class, allowing everyday low-end cars to have audio-level sounds or voice prompts. By providing smooth communication to the SPI port of the automotive network system, system integration becomes extremely simple. ISD15D00 uses external SPI flash memory audio with built-in regulator PWM speaker driver, analog digital input and output, suitable for multi-language storage devices and audio playback of up to 64 minutes. The ISD15D00 voice macro is designed for situations where, for example, the language of the external flash memory changes but the application software does not.

Human-computer interface uses two directions of information exchange:

- machine → person

- Man → Machine

Human-machine interface in cars:

In the process of human-machine dialogue, the driver plays an important role. They must use the necessary information required to perform the action so that their safety is not compromised. Therefore, it is extremely important to use interfaces and dialog functions that are designed to ensure reliable execution of various operations under all circumstances. To eliminate distracting distractions such as annoying beeps and sounds, voice alerts and voice prompts can play an important role during operation.
