Questions & Answers

Q: How does the Wii Remote transform into an interactive whiteboard?

The Wii Remote, coupled with an inexpensive infrared pen, allows the camera to detect the pen's infrared dot, replicating an interactive whiteboard. By mapping the camera pixels to the projector pixels, users can draw, write, and interact with the projected surface.

Q: What are the limitations of using the Wii Remote for an interactive whiteboard?

While the Wii Remote approach offers cost-effective access to interactive whiteboards, it falls short by approximately 20 percent compared to higher-priced solutions. Although it may not provide the full range of features, it still offers a significant advantage in terms of cost and accessibility.

Q: How does the Wii Remote enable 3D head tracking?

By attaching infrared dots to a pair of safety glasses, the Wii Remote can approximate the user's head location in relation to the computer screen. This information is then used to change the displayed image based on head movements, creating a 3D-like experience.

Q: How did YouTube contribute to the spread of these ideas?

YouTube played a crucial role in rapidly disseminating the researcher's work. Within a week, the video showcasing the projects had a million views. This led to engineers, teachers, and students worldwide creating their own videos and sharing their experiences, effectively spreading the ideas and inspiring further innovation.

Q: Can the interactive whiteboard software be easily accessed?

Yes, the researcher has made the interactive whiteboard software available for free download on their website. In just three months, it has been downloaded over half a million times, benefiting teachers and students globally.

Summary & Key Takeaways

• The speaker showcases two demos using the Nintendo Wii Remote to create an affordable interactive whiteboard and enable 3D head tracking.

• With just $50 of hardware, schools and offices can have their own interactive whiteboards, providing accessibility to those with limited budgets.

• The Wii Remote's infrared camera allows for multiple dot tracking, making it suitable for both single and multi-touch interactions.
