Problem: There is written telephone number. It can be written on a wall, or a web page on your screen.

Solution: An app that can OCR a photograph and find telephone numbers and then open the phone to allow the user to call. I have done similar through Google lens – but that included lots of tapping and swiping. This solution is 1 app that is stream line for this.

Problem: sharing a screen and no walls are available.

Solution: Project the image on a table.

Put the projector on a tri pod. Put the projector on your open laptop and let the laptop lid/monitor be a tripod. Add magnets and attach it on the ceiling somehow.
