Show a user that no interaction is possible on a picture frame
I'm currently using a connected picture frame at my house. Since it has UPnP capability I'm able to tell it to search for a picturer in a DLNA share. On the other side, a script modifies the picture displaying useful things in quite real time:
- time
- weather
- tasks and chores
- agenda
Since it's a picture frame, no interaction is possible it just displays information (refreshed every 5 seconds or minute). But in an era of "everything is touchscreen", how to show that touching this picture frame won't do anything?
- Is there a visual clue instead of a "touching won't do anything" message?
- I saw a previous question about clickable boxes, I'll try to respect that but are there other options?
I know that "he makes mistake once, he won't do it again" could work but I'd avoid cleaning fingerprints on my frame everytime ;)
This picture frame has really no interaction possible, it just has a remote control with arrows to select previous/next picture and summon a settings menu.
It only displays a picture, not a website so there is no navigation possible (the picture is generated with PHP's GD library)
