AREA Safety Infographic
1. Fixed to screen space
All elements are locked to the screen space as per traditional app UI and don’t relate to the real world. These AR experiences lock to the screen in the same way a responsive website would and rely on the user to position the camera in a specific way to experience AR.
2. Real world related
The AR UI relates to the environment and the physical world around the user. This is used for apps such as Yelp’s monocle feature, allowing users to see reviews of the best (and worst!) restaurants around them.
3. Object related
The UI is attached to a particular object or trigger in real world space. We’ve produced a few apps with this UI integration for brands such as Black & Decker and Delphi. These can be real world objects that have interaction tethered to them or digital objects that are triggered by scanning a marker.
1. Context awareness
One of the main challenges of AR is to understand and adapt to the context of the user and the environment. AR should provide relevant and useful information and interactions that match the user’s goals, preferences, and location. For example, an AR app that shows historical landmarks should not display the same content in a museum and in a park. To achieve context awareness, web designers need to use various sensors and data sources, such as GPS, camera, microphone, accelerometer, and gyroscope, and apply machine learning and computer vision techniques to analyze and interpret the context.
2. Visual clarity
Another challenge of AR is to ensure that the digital content is clearly visible and legible on the real world background. AR should avoid cluttering the user’s field of view with too much or too small information, and balance the contrast, brightness, and color of the content with the environment.
3 User control
A third challenge of AR is to provide the user with sufficient control over the AR experience. AR should allow the user to adjust, manipulate, and interact with the digital content according to their needs and preferences. For example, an AR app that shows furniture models should let the user resize, rotate, and move the models around their space. To provide user control, web designers need to use intuitive and consistent input methods, such as gestures, voice, or touch, and provide feedback and guidance, such as icons, labels, and sounds, to indicate the available actions and their outcomes.
4 User comfort
A fourth challenge of AR is to ensure that the user is comfortable and safe while using the AR technology. AR should avoid causing physical or mental discomfort or fatigue to the user, such as eye strain, nausea, or confusion. For example, an AR app that shows virtual characters should not make them too close or too fast to the user’s face. To ensure user comfort, web designers need to follow ergonomic and accessibility principles, such as limiting the duration, frequency, and intensity of the AR sessions, and providing options to adjust the content and the device settings.
