“Fuji Xerox’s “Fourth-Dimensional Pocket Project” is a “dream” project that challenges key small-to-medium enterprises to work together to develop the gadgets that appeared in the hugely popular manga “Doraemon” as a major motivating force to support Japan.
Yukai Engineering Inc was responsible for design, planning, and implementation of this project’s second gadget, “Telephoto Megaphone”.
Using the scope to aim the gadget at someone in the distance, it’s possible to project your voice to them. This megaphone allows you to pinpoint your voice directly into the ears of people standing far away.
