There is an increase in the number of remote-controllers that come with almost every domestic appliance. But today poeple are much more interested in richer and more intuitive interactions with objects using touch, voice or even gestures. Considering the end-user perspective for smart home related research, easy interaction with far away objects becomes extremely important. So it is very interesting to study "point and control" interaction in a smart home.
-What is the acceptable range of pointing device- From how far do you want to control the objects in your environment?
-What is the required accuracy of a pointing gesture?
-Is it always better to point directly at object, or point at something which represents the object?
-Do you choose the object first and then choose the functionality, or choose the functionality first and then point at the object?
The spotlight metaphor
The projector’s illumination acts like a spotlight which displays only certain parts of the virtual space, depending on where the projector is pointing. This metaphor is also known as the “peepHole interaction”.
The X-ray vision metaphor
We made an effort to realize superhuman powers in terms of “drilling” through a wall to visualize the scene behind it.
A novel interaction technique for controlling connected objects in a smart home. Objects can be within the field of view of the user or outside it
A high end ART tracking system is utilized to continuously gather the orientation adn direction of the handheld controller. The controller has a projector inside it, which continually modifies the projected interface depending on the pointed direction. There are a few buttons on the controller which are used to interact with the projected interfaces
A slider on the controller is used to virtually go through the wall and look behind it. Objects behind the wall can be seen now and controlled in the same way.
