Abstract: Human behavioural characteristics in an augmented reality session having a product under development are detected. The characteristics are transformed into performance metrics that together with identified product features define metrics for each feature. A smartphone (110), a system and a method for a virtual object on the augmented reality are disclosed. The user (230) examines the new design or product in the augmented reality environment, for example, where features of the design are presented in a relatable context or in a familiar environment. The user (230) may control the virtual object on the augmented reality view by a display device, for example, by a smartphone.
