Nice hunt @afzaal4!
The 'DOTTI' looks like a fun multicolour dot matrix device that alerts you to phone calls, messages and other notifications.
It also serves as a clock and it can make patterns that react to music too.
Although this is primarily a fun product, I believe this could be useful to alert people with impaired hearing or no hearing at all to give a visual alert to them too.
