One of Sega's prototype Dreamcast controllers looks very similar to the Wiimote. So, what were Sega planning back in 1998? And did Nintendo copy their idea?

While looking through some old console prototypes over the weekend, I stumbled across what is described as a prototype controller for the Dreamcast. It looks remarkably similar to the Nintendo Wiimote, with a trigger on the bottom, buttons on top and wireless technology. All that's missing is the Nun-chuk attachment. 
Were Sega planning to release their own version of the Wiimote way back in 1998 when the Dreamcast launched? 
After doing a bit of research I was unable to find any further information about this mysterious prototype. Who was it made by? Was it an official Sega controller? Why wasn't it put into production? And perhaps most importantly, who designed it and what was it going to be used for? 
Perhaps the designers behind the Wiimote were responsible for this design, back in 1998. It seems unlikely, but the two controllers do look similar. 
If you have any further information on this mysterious prototype please contact us and we will update this page.
