They will use the phone/tablet device as a touchpad to move around the connected computer screen. Requirements 1. Windows Demo app to display unique web url which will have full URL of the kiosk to connect to for control (got from calling web service with GetRemoteScreenControlSession call 2. Unique url to change – ‘Change barcode’ button in windows demo app to get different unique session/URL from web service (we will change this on each use in our production app) 3. Windows demo app is .Net Core 3.1 Windows Application 4. Web service is Microsoft .Net core 3.1 5. Needs to operate via web service acting as proxy, no direct traffic to client (in production port 443). I believe this should use SignalR but can suggest other technology. 6.

Defined ‘trackpad’ area – user will drag finger to move cursor c. touch screen cursor movement (move cursor around screen area on kiosk) d. left mouse click by finger tap on screen (no right click needed) e.
