Did you have a chance to look at the prototype multi-line braille and graphics 
display exhibited at CSUN by the Dot company from South Korea? I did, and it 
was impressive even as a prototype. There were some software issues, but the 
hardware was undoubtedly working - and that's where the engineering challenges 
lie.

Another impressive device at CSUN was the Canute Braille Reader - not really 
intended as a display for interacting with a computer, due to its slow, line by 
line refresh rate. Rather, it's intended for reading documents (i.e., BRF 
files) - 9 lines of 40 cells each.

The Graphiti graphics display under development by Orbit Research and American 
Printing House for the Blind was, I think, also exhibited this year, although I 
didn't look at it while at CSUN - I've had my opportunities elsewhere. For 
anyone who works with tactile graphics, this device is impressive and very 
likely to be a major advance.

There may have been other interesting devices that I missed.

    Hello Everyone,  
    
    Today, I went to the exhibit hall at the 2019 CSUN Assistive Technology
    Conference here in southern California.
    
    Among other goals, I was interested in test driving a few Braille displays
    for use with my iOS devices.
    
    Imagine my surprise when I arrived at the A.P.H. booth and discovered that
    they had no Orbit Reader 20s on hand for visitors to explore.  While I was
    there, 2 other people walked up and asked about the Orbit Reader 20 and were
    equally disappointed at the lack of a demo model.
    
    I did, however, get a look at an entire host of other BRaile displays, from
    other companies, including the latest version of the Focus 40.  Now, that,
    is a beautiful device.
    
    Regardless, I was sorely disappointed at not having an opportunity to test
    drive the Orbit Reader 20 Braille display.
    
    And the beat goes on,
    
    Mark
