"By developing both the Braille integration technology and the middleware or plugin that interacts with the POS system UPOS is able to be either a stand alone mechanism or integrated and adapted to a currently running POS system. The middleware interprets the selected Braille characters and translates them into the corresponding HTML/PHP commands or functions within the POS system. Transactional functions on both ends are encrypted, parsed and registered so that it is in essence a three party process that adapts human interaction into the defined systematic functions".

pseudocode for command interpretation (in beta)

code language

In order to bring together numerous pieces of software and developmental tools there was a need for "pseudocode" which is a series of HTML/PHP codes that mimic the native POS language running on any given system. These pieces of code are plugged into the UPOS operating system to get full access to its capabilities without crashing in the event of user error. It can best be explained as protection from over-clicking that sends too many repeated commands to the POS, causing the need for HTML/PHP codes to step in and automatically make the correct choices using the AI and learned data analysis tools.

UPOS - Universal POS Interface User Manual

Overview

UPOS is a simple and accessible point-of-sale system designed especially for vision-impaired users. It uses audio feedback and a touchscreen with Braille stickers for easy navigation. The large buttons and spoken prompts make it easy to use.

Grid Layout and Braille

The screen shows 20 squares arranged in 4 columns and 5 rows.
Out of these, 18 squares are active buttons; the other 2 are blank.
Each button matches a Braille number and/or letter.
Braille stickers are placed on the touchscreen to help users find the right buttons by touch.
Buttons are numbered starting from the top left (button 1), then top right (button 2), continuing row by row from left to right.

Main Buttons and Pages

Buttons 1 to 10 are the main order function buttons.
These buttons repeat on up to 8 pages of commands, controlled by the connected host POS system.
This lets users access many commands while keeping the important buttons in familiar places.

Quick Start

Press button 1 to start an order.
Choose TOGO or DINE-IN.
Select the category of the item you want.
Pick the specific item.
Choose the size and add any toppings.
Check the subtotal.
Make a payment.
Complete the order and print receipt.

Troubleshooting

No speech or audio?
Check your device volume and browser support for speech. Reload the interface if needed.
Touchscreen not responding?
Make sure the screen is clean and Braille stickers are correctly placed. Restart the software if it still doesn’t work.
How to switch pages?
Use the host POS system to change pages. Buttons 1-10 stay the same on all pages.
Want to customize buttons or add modifiers?
Contact your POS administrator to update the menu or add options.
