The Steam Controller was announced by Valve last year and now the lastest design for this gadget has been revealed by the company. The Steam Controller is the perfect gaming gadget designed to fit your living room and will revolve around and make use of the Steam OS and Steam Hardware. This new controller will be revealed at the GDC event taking place next week and we are expecting more design changes to follow up till the launch of the gadget later this year.
This latest design deviates from the original prototype design which Valve showcased last year. The prototype had massive touchpads on either sides and these were also supposed to work as speakers. Along with this, there was a touchscreen in the middle of the gadget and it was surrounded by four keys. However, in this latest design, the middle touchscreen has beenm canned and in its place there are four direction keys and four action buttons which have been marked as A, B, X and Y.
