Human Computer Interaction with Shadow

This paper proposed concept and prototype of an intuitive user interface based on shadow for indoor environment. Shadow is a common phenomenon in our daily life where there is light source. It always exists but we ignored the potential of shadow for connecting digital and physical world. There are several merits of shadow interface: First, shadow is a daily life familiarity and it builds a natural bridge between digital and physical worlds; Second, this system is simple and does not require expensive devices; Third, shadow itself is a strong and natural visual feedback cue for the user to take good command of applications.

In Spatial Augmented Reality (SAR) environment [1], our daily life working space can be extended by projectors to every corner of the room. However, traditional 'direct-touch' style interfaces such as DigitalDesk [2] still limit us within the desk area. So, designing spatial interaction method is an important and necessary task.

Future applications: possible applications include:
- Assistance to presentation based on projector
- Entertainment
- Media art
- Educational interaction in museums
- Touchless interface in hospitals
- Remote control inside intelligent house

rocket science :) that was so pretty

[rhixzify]

hey! may I know how you did this? :) thanks

[Duckzify]

Very interesting, continue studing that hardware!

cool

Nice experiment. But i think that professionals wouldn't be so happy to be obliged to hide part of the screen to draw. That's a nonsense, When I sketch I would have a vision of everything that I did on the screen until that moment.

Cool!
