Abstract

User input is a recurrring problem in augmented reality interfaces. Usual approaches include voice commands or very simple physical interfaces (a few buttons), but these have drawbacks. Here is proposed an input method based on recognizable gestures done by just steering the AR view while an object is in a specific zone of the view. The final effect is an effective replacement of both the "move pointer" and "contextual menu" concepts, based on simple movements.

Inverted Free-Hand Controls for Augmented Reality

    Augmented reality is the superposition of synthetic content on top of real world live view; object recognition/tracking and rendering techniques are used to create the virtual elements. A fundamental part of the Augmented Reality world is interaction with the virtual objects, but the available means of giving input to the system are not as powerful as one would hope. An inherent difficulty is the ability to appropriately "click" objects which have to physical presence. It often happens that voice commands become the preferred input mean; but voice commands have some limitations (accuracy, speed, robustness, privacy). Better ways to give inputs are needed in the AR field especially focused in the free-hand scenario such as during physical working tasks or in case of disability.

    The user wants to selecting and execute - without hands or similar interaction - one o more contextual actions over an identified object in a AR scenario. Because in an AR world it is the user that moves the view on the world, he can act by the mean of the AR view in order to make the recognized object describe a shape i.e. a circle or a spiral. The new feature deduce the will of the user and presents the available contextual action tat can be executed in the same way.

    Augmented Reality consists, among other things, in recognition and tracking of real world object. An anonymous object can be properly detected by the visual analysis software, especially if it contains some h...
