Povzetek

Znani proizvajalec igrač Nintendo izdeluje igralno konzolo z imenom Wii. Srce naprave je brezžični krmilnik (remote) z infrardečo kamero, ki zaznava gibanje in položaj v prostoru. Naprava deluje tako, da jo igralec drži v roki in vgrajena kamera zaznava njegovo gibanje. Na ta način lahko navidezno igra različne, tudi športne igre (tenis, bowling ...).
Ameriški raziskovalec Johny Chung Lee je osnovni princip uporabe Wiija obrnil na glavo. Wii krmilnik je pritrdil na nosilec in za izvor infrardečega sevanja uporabil LED-diodo, ki jo je vgradil v svinčnik. Napisal je program, ki povezuje gibanje svinčnika z gibanjem miškinega kazalca na računalniškem zaslonu. Vse, kar je še potrebno, je, da sliko projiciramo na podlago, v katero je usmerjen krmilnik, in že imamo interaktivno tablo, mizo, zaslon, omaro, steno ali tla učilnice. Genialnost ideje je v preprosti izdelavi pisala in v možnosti, da lahko katera koli podlaga, na katero projiciramo sliko, postane interaktivna ter seveda nizka cena Wii krmilnika.
V delavnici SIRikt-a bo prikazano, kako povezati Wii z računalnikom, kako izdelati elektronski svinčnik in kako uporabljati to preprosto in ceneno, vendar uporabno igračo v pedagoške namene.

Ključne besede: Wii, interaktivne naprave, brezžični krmilnik.

Abstract

A well-known toy manufacturer Nintendo makes a game console called Wii. The heart of the device is a remote controller with infra red camera that detects movements and position in place. The device operates so that the player holds it in his hand, and the built-in camera detects the motion. In this way you can play different, even sports games (tennis, bowling, etc.)
The American researcher Johnny Chung Lee has turned the basic principle of Wiija upside down. Hi attached Wii controller to a carrier and he used the source of infrared radiation using LED, which was installed in the pen. He wrote the program that links the movement of a pen with the movement of the mouse cursor on a computer screen. All one needs to do next is to project the image onto a substrate targeted by the controller. This way you have an interactive whiteboard, a table, a display rack, a wall or the classroom floor. This genius idea is reached by the simple construction and the possibility that any of the grounds on which the image is projected, becomes interactive and, of course, the low price of the Wii controller.
In the workshop SIRikt it will be shown how to connect the Wii to a computer, how to create an electronic pen and how to use this simple and inexpensive but useful toy for educational purposes.
