Increasing complexity of human-machine interfaces (HMI) in automotive design is a major challenge for designers. The number of vehicle features and functions has increased exponentially over the past few decades, and designers must provide controls for this increased functionality. To meet this challenge, some design teams opt for analog controls, with physical buttons and screens for different features. But with so many options available, designing a user interface with the correct amount of artistry and functionality is not an easy task.
One of the challenges of designing HMIs for cars is driver distraction. While driving, the presence of electronic devices in the car can easily distract a driver. In response to this challenge, automotive manufacturers are developing innovative and flexible solutions for HMIs. For example, most cars currently use capacitive touch screens, buttons, and knobs. However, these systems do not provide tactile feedback, which leads to driver distraction. In order to combat this problem, the automotive industry is adopting haptics technology. This technology uses a device that creates a sense of touch to make it more natural for the driver to operate and navigate.
While HMIs can be used to control navigation, they should be designed to keep the driver's attention. Users cannot keep a lot of information in their short- and working memory, so they should be able to quickly access important information. For example, an ideal HMI should answer key questions on the home screen. In addition to this, manufacturers should consider incorporating key information into their vehicle's instrument cluster or head-up display (HUD).
The next phase of human-machine interface development in automotive is the emergence of adaptive and programmable technologies. The goal is to provide drivers with a seamless experience while using their vehicle. A human-machine interface is designed to be intuitive for the user. A car's HMI should be capable of interpreting and responding to the user's inputs, allowing for easy navigation. In addition, it should also be scalable and easy to install.
The next stage of HMI development in automotive is a significant step in integrating new technologies into automobiles. As a result, car makers have begun introducing new augmented reality experiences into their vehicles. The 2022 Mercedes S-Klasse, for example, will feature a head-up display that projects graphics directly onto the windshield, providing important information in context. The design of the HMI for automotive HMIs must be intuitive, allowing users to locate relevant skills quickly.
