I think this Philips 'In Touch' will suit as an electronic touch screen outside classrooms and offices rather than as a family message center.

This cool stuff is a dashing display, since it allows you to leave a message as text, picture or video clip or send one from a distant basis, thus I prefer it as a notice board screen.
Operation is quite simple:
touch the mirror with a Stylus and a drawing space opens. To record a video message, touch a blue light in the right-hand corner of the mirror, which turns red and a real-time image of the person recording the message appears in the centre.Even SMS and MMS functions are available - just make a message with the stylus then draw and leave the message square over the photo of the person you want to send.
So stay in touch with family members even while they are out of the house or use it as a community board.
