I have only used the Canute 360 briefly at a conference. As I remember, 
the display was updated only one line at a time. Refreshing the entire 
display was slow and noisy. It didn't have any form of touch sensor to 
detect reading position. However, the braille was clear and easy to 
read. Graphics were supported, but they had to be constructed from 
ordinary braille cells. In the Monarch, the pins are at an equal 
distance in both dimensions, facilitating graphical rendering (96 by 40 
pins, or equivalently 32 braille cells by 10 lines maximum, allowing for 
the inter-cell spacing).

I haven't used the Dot Pad, but I was shown a prototype of Dot's 
technology at the 2019 CSUN Conference. So I'll leave it to those with 
more current knowledge to comment on the Dot Pad.
