A real time remote control solution for information systems.
It allows to command a set of slave displays using a remote control app.
Examples:
- Commercial displays at storefronts or restaurants.
- Public Information for cities, airports or transportation centers.
- Industrial active information screens.
First you bind devices and then you can assign views to them.
Basic concepts:
- Device is any networked machine.
- Component is a reusable module of code.
- Scope is a namespace to store variables.
- View belongs to one user and includes a component and a store.
Procedure:
- Navigate to nabla.net in one device. You get a QR code.
- Scan the QR using this app or Google Lens.
- The device is bound when the QR goes away.
- Select a view using this remote control.
- Edit or create your views.
A cheap solution to deploy displays is using a Raspberry PI in kiosk mode.
