Magic Mirror with touchscreen Display/Monitor

Snille

@core I also used a IR-Frame in my build. Works very well if you just want “simple” point and click and/or point and drag (even with two fingers)… I have not tested it with more advanced stuff. :) But for the MM it’s great. You can read about my build here and underneath the picture, you can find a link to a full photo album with pictures and text to all pictures about what you see. :)

Hi,

thank you very much for your replies.

An IR touch overlay is unfortunately not possible in my case. The mirror is frameless and clamped in 4 holders (2 above and 2 at the bottom). That’s why i am looking for a touch display which can be mounted under the glass.

Best regards

that doesn’t exist. the monitor is dependent on human skin resistance (try it with a glove on)
the mirror glass would block that

Ok, but a PCAP Touchfoil under the glass, mounted between a LED display and the Mirroview, will work for sure (asked Pilkington and the company selling the foil).

@core but this is effectively the same as the ir frame… the special touchfoil does the work… NOT the monitor…

I have a 24" one that after I bought it found out that it will not work in Linux so my only option is to install MM on Windows … ugh. So when I can come across a NUC or something small I will until then …

@Snille Hi Snille
I have had greate use of xin.sh file to run at start. It contained the:
“DISPLAY=:0.0 xinput --set-prop “Multi touch Multi touch overlay device” “Coordinate Transformation Matrix” 0 1 0 -1 0 1 0 0 1”
However, now using the pm2 start xin.sh for automatic start, I get an error in the pm2 log
What do you use to correct the ir-frame ?
Best

@BJK what is the error?

@sdetweil

Well, I start the xin.sh with PM2 and it works with calibrating the IR-frame:

xin.sh:
#!/bin/bash
DISPLAY=:0.0 xinput --set-prop “Multi touch Multi touch overlay device” “Coordinate Transformation Matrix” 0 -1 1 1 0 0 0 0 1

However, after the mm.sh (the MagicMirror) has started, then when I go back to Raspberry disktop the the Calibration is off again. If I then run the xin.sh with “pm2 start xin.sh” in a terminal window then the calibration is okay again.

This is the error that I get from pm2 log file:

Should I do something else with pm2 or run the xin.sh in an other way?

It would be so nice to have i done automatically :beaming_face_with_smiling_eyes:

It would be so nice to have i done automatically 😁

the mm.sh file:
cd ~/MagicMirror
DISPLAY=:0 npm start
