We do not know if the following is supposed to be a future Casio calculator model or a scrapped idea, but at one point, it appears that they might have had plans to release a new touch screen calculator model in the future. Forum members found the following:

I usually search the patents belonging to various companies (like sony, apple, samsung, microsoft...) to know at first hand the technological innovations.

Recently, I decided to do a patent search of Casio and I found what may be the next Casio calculator with touchscreen technology.

Below is a draft, possibly a prototype:



Features of this "future" new calculator:
-Multitouch screen


-Possible wifi connection

-HANDWRITTEN MATHEMATICAL FORMULA RECOGNITION

Those two quotes are available at http://ourl.ca/17074 with some discussion. New or not, that stuff is nonetheless interesting. In October 2010, what was finally announced to the public was the Casio PRIZM series, the second color screen calculator one from Casio, the original being the CFX series from 1995. released on New Year 2011. TI responded with the TI-Nspire CX during Spring 2011, although some sources state that TI had worked on the CX since February 2010.

Unless Casio started working on the PRIZM long before TI did on the CX?

Yeah I guess. One thing I wonder is if for example Casio started working on a color calc if TI somehow managed to sneak in and discover their plan or vice-versa? If Casio was just starting up, then TI could have started soon afterward, or if it's the opposite, then maybe Casio rushed in the PRIZM?

Well, I don't think a color screen is a very unique idea for either company, the real issue is deciding when the market is ready for it.

Same with touch-screens IMO as they are now everywhere ^^

Did the patent documents not have dates? That could easily tell us whether it's a recent development. If it's pre-prizm by a large margin, I'd say it was scrapped.

The latest patent related with This suposed touch model is aproved on 27 September and is a system to recognit picture plot equations with reference a touchscreen calculator - http://6xn.xo.sl.pt
So they are still working on This...
