Touch overly VS. "Smart Glass"



  • Hello all my name is Armando, and i’m new to the Magic Mirror scene so please bare with me.

    I ran across this thread and i was wondering if anyone has used similar setup like @Mykle1. I’m looking to add a touch overlay behind the acrylic glass? if you have how did it respond and i am looking to use the mirror side of the acrylic.

    I found a few places that sell Smart glass but they are kinda expensive. if you know any inexpensive smart glass sites please let me know
    thanks inadvance



  • I’m going to be working on this soon, after I get my modules reacting to my mouse. I think putting a transparent capacitive touch panel, in front of the mirror, might give you this effect. If you want to put the mirror on top though, I think you’re looking for a resistive touch panel.

    I’m using a 32" IR Touch frame… it works REALLY well… very responsive.

    Yes, but he would like to know if works with acrylic as opposed to actual glass. I could not help him as I don’t have real glass OR a touch screen.

    An IR-frame isn’t affected by the type of mirror (since it is placed in front of everything).

    Touch foils (pcap) however can’t be used on glass with metallic coatings, which most of the mirrors have, because the metal distorts the readings of the foil sensors.

    With that said I don’t know how the touch foil would react behind an acrylic mirror but my guess is that it most likely won’t work. (As most plastics are prone to get staticly charged and that could probably have a negative impact on the touch foil as well).

    This could actually work, it will build on the thickness and weight of the mirror but you could have a really thin frame instead of a IR-frame around it.

    So it would be layers like :

    Glass
    Touch foil
    Air gap
    Mirror
    Screen

    I’m using an IR frame with standard window glass (1/8") thick.



  • @cowboysdude Yes mykle1 is correct. My plan is to turn it into a selfie mirror. i ran across this website that claims their glass works well with touch screens but like most people on their first build i’m trying to keep the cost down. So if i could use the same acrylic as opposed to a $350 glass i want to do it.



  • here is what i am trying to build

    But I want to start off small with a “table top” maybe 22" wide x 34" High or something like that.
