Popular examples include voice assistants like Google Assistant, Apple Siri, and Amazon Alexa. These devices can execute a wide range of commands, from controlling smart home systems to retrieving information and setting reminders. Voice control is valuable for hands-free operation, offering a convenient and accessible means of interaction, especially with disabilities or when multitasking.

Gesture-Based Interfaces

Gesture-based HMIs use sensors or cameras to track and interpret hand or body movements, allowing it to control devices or software without physical contact. These systems typically rely on technologies such as infrared sensors, depth-sensing cameras, or motion detection systems to detect gestures and translate them into commands. A notable example is the Microsoft Kinect for Xbox, which allows  to play games by simply moving their body and hands, without needing a traditional controller. Gesture recognition has broader applications, including virtual reality (VR), robotics, and even health monitoring, where gestures can be used to control devices, improve engagement, or track activities.

Brain-Computer Interfaces (BCIs)

BCIs enable direct communication between the human brain and external devices, bypassing the need for physical interaction. These interfaces interpret brain impulses, allow to control computers or robotic systems purely through thought. BCIs have great potential in fields such as healthcare, where they can aid individuals with disabilities by providing control over prosthetics or assistive devices. Neural prosthetics, which translate brain signals into physical movements, are example of BCI applications. Early robotic control systems also explored brain-machine communication, though the technology continues to evolve for more complex and use cases.

Wearable Interfaces

Wearable interfaces integrate technology into devices that can be worn on the body, providing constant communication and interaction. Devices such as smartwatches, fitness trackers, and augmented reality (AR) glasses have become increasingly popular for their ability to offer continuous data collection and  interaction. For instance, smartwatches allow  to monitor health metrics, receive notifications, and interact with other digital systems directly from their wrist. Augmented reality glasses enable to overlay digital information onto the physical world, enhancing some experience with contextual data. Wearable HMIs are  effective in applications where mobility and hands-free operation are important, such as in healthcare monitoring or industrial settings.

Each of these HMI types enhances human interaction with technology in unique ways, allowing systems to adapt to various contexts, preferences, and technological environments.
