chair introduced Dave Schleppenbach giving a brief CV
Schleppenbach introduced refreshable braille tablet project
Schleppenbach summarizes the importance of multiple line braille display in the context of teaching chemistry and STEM
Schleppenbach emphasizes the importance of braille literacy
Schleppenbach describes the technical challenges of the project (3k-6k dots needed)
Schleppenbach describes the user interface design challenges inherent in the project.
microsecond response rate in the electronics
design concepts - similarity to paper brail - size and form factor comperable to a tablet or laptop computer - content availability
progressive web apps should be usable. Most of this can be coded in java / javascript
DRM concerns are minimul from publishers - BRF capable device
key questions - how does a blind user interact with a full page display
what types of format work (40 cells vs 32 cells etc)
how do we teach with a device like this?
how do we help people to improve their literacy
how would we utizile a tablet of this nature to incorporate interactive content
cary - asks about tactile graphics capabilities
Schleppenbach - first run has a modular braille cell aproach - so evenly spaced vertical lines and non evenly spaced horizontal lines
Schleppenbach - this could be added through touch layer or detecting dot motion which is possible tecnhically
Schleppenbach - no branding name yet - intended to ship this year
Schleppenbach - smaller size tablet 24 cell x 16 line ~3k dots in 8 dot cells - cost estimate is 4k-5k price range
Schleppenbach - not a linear cost increase with cell size
Schleppenbach - dumb display options are a posibility - tablet has android with an application layer using wiffi usb or bluetooth
Schleppenbach - should work with a device like a computer or phone or ta blet
Schleppenbach - Yes - we have been working on a touch surface with holes drilled in it for the top surface of the device - most gestures aren't useful due to haveing your hands on the device
Schleppenbach - small touchpad is also an option under consideration
Schleppenbach - dot and half spacing between cells - we could add more dots - current version prioritized braille spec
Schleppenbach - we could move to a non braille spec in the future
Schleppenbach - not of particular interest

A - Neil - there is a tag in HTML for this - in MATHML there will be a subject area tag / attribute. the excercise here is to dtermine how fine a grain we need
Neil - proposes a chemical formula tag and other possible tags based on subject.

concerns of the work needed for author level disambiguation were discussed
george - reqyests that work continues between calls
scheduling discussion ensued
2-20-2020 at noon eastern
next meeting
ageneda - continued work on examples and disambiguation
chair concludes meeting
<George> Next call February 20, 2020 at 17 UTC, noon Eastern
