Natural user interfaces and new languages

The first question to be asked in the design of these NUI-based instruments is the nature of these interactions (vocal or gesture): which interactions can be considered natural? The "naturalness" of gesture-based interfaces very often configures and manifests itself effectively when interpreting actions that the individual naturally performs to manipulate an object physically (e.g.: swipe). Then there are gestures that we can define arbitrary but used widely (e.g.: like, thumbs up).

These are just some of the aspects that compete in the design of a system based on AI and NUI but for all the real test remains linked to the ability to trigger a fluid experience, correct and without cognitive efforts. This scenario brings us back to the possibility of reducing the behavioural exceptions in the experiences offered in a store or in a public space and thus reducing the management costs of these exceptions.
We use the body as a tool to generate basic information: presence or our absence for instance. This simple information produces an automated reaction (for example opening, closing, switching on, switching off, etc…). But when the body, movements and gestures generate more complex and comprehensible information for NUI and AI-based systems, we can talk about language, that language that no longer produces simple automated reactions but real collaborative interactions with machines. Systems based on AI and NUI applied to the real context allow to promote virtuous changes especially in situations such as the one we are living in where individual responsibility must be accompanied by a constant behavioural education. AI and NUI based systems also allow to detect, correct and discipline behavioural anomalies.
