The design must not give any false alarms, potentially sending the user into a panic. This is a more complex use of multimodal design because the balance of inputs to outputs needs to be calculated correctly. Once these inputs are stored, devices and services such as Fitbit and First Aid by The Red Cross provide valuable, lifesaving warnings in the form of a vibrating alert, a taptic вЂњtapвЂќ on the wrist, or an audible alarm. We can measure inputs such as stress levels, heartbeat, sleep cycles, water intake, and in the near future, glucose levels.

We are now capable of capturing more complex inputs from users using smart devices. A Complex Multimodal Design Experience: Health Next, Robert could either use a remote control or ask the AI-enabled assistant to turn down the heat when he walks in. For example, turns on the lights, adjusts the heating and cooling, and deactivates the alarm system. The system recognizes that he has arrived and starts a sequence of automated actions. His home automation system is triggered once he gets within a mile of his garage. A Simple Multimodal Design Example: The SmartHome Multimodal design is also helpful when designing for people with certain limitations and disabilities. The Apple Watch is a great example of multimodal interaction design. Receiving a message or swiping left to skip a song are two examples.

Haptics, gestures, and motion rely on our perception of touch (tactile abilities) to trigger an interaction.

This includes any voice assistant, such as Alexa, Google Assistant, or Siri.

A voice user interface relies on our auditory capabilities to interact.

A graphical user interface relies on our vision to interact, for example, with a website or a digital billboard.

Here are a few more examples we commonly find in multimodal design: When driving, the obvious choice is to use our voice for making a phone call or navigation, but when parked, itвЂ™s most likely easier to use the touchscreen or a scroll wheel to interact with the system. Most of these systems allow users to interact with voice and touch. If there was only one modality mechanism, it would negatively affect the user experience and the design would вЂњfailвЂќ in the mind of the user.ДЄn example is a car infotainment system. As everyone uses products in different ways and in different contexts, users are provided with several feedback mechanisms and given multiple ways to interact with their computer.Дesigners make life easier for users by incorporating and automating actions through different modalities.

The idea behind multimodal design is to combine multiple modalities in order to improve a productвЂ™s user experience. Nintendo Switch controllers being used for in-game archery are an example of multimodal interfaces. This brings many more opportunities to create a unique and engaging user experience. Think about playing a game of tennis on a console and using the gamepad to emulate the movement of the racket. More complex examples are accelerometers, gyroscopes, and magnetometers that help with motion detection. In this case, users rely on various mechanisms to communicate with and command computers. A few examples are keyboards, mice, touchscreens, trackpads, and speech recognition. WeвЂ™ve invented several ways to interact with computers. A few examples are computer graphics, audio playback, phone vibrations, and smartwatch taptic feedback. The most common computer-human modalities rely on vision, hearing, and tactile abilities. Computer-human ModalitiesД¬omputer-human (or computer-to-human) modalities help a computer understand what the user wants. Each of these interactions includes various modalities such as voice, touch, and taptic feedback. Using multiple modes of interaction is what multimodal design is based on.Д«efore we explore multimodal design, letвЂ™s begin with a basic understanding of two types of interactions: computer-to-human and human-to-computer. If she chooses, she can tap on the screen instead of using her voice.

Using touch and voice she interacts with the app, telling the video to pause, fast forward, or replay a specific section. A mother getting ready to prepare dinner at home opens a cooking app on her iPad or SmartTV.
