This last device was only announced in Japan a couple weeks ago, and as you can guess from the name it is a navigational tool. It was developed in partnership with Fujitsu and Aichi Medical University Hospital. The Navit has a 5" E-ink screen, and it is intended to be used as a replacement for the paper and verbal instructions given to patients.
There isn't much beyond the Navit that is new; everything else has been shown off at previous shows like CES and previous Computex and Display Week trade shows. Charbax missed only other new item at Computex, but Engadget caught sight of a several inch long display intended for a wrap around smartwatch.
And as you might recall, E-ink announced a 32" color sign product at SID Display Week, which of course they did not have on display at Computex.
