1) Can you tell me if realwear HMT-1 support Vuforia Chalk?(Yes/No)
No. Refer to the Chalk download page here for details on what is supported. This might change in the future, but the page should be current.
2) If it does, from where can i get the apk?
3) Is it free or not?
There is a free version and a commercial version. The commercial version has a bunch of additional features over the free version including: unlimited call lengths, central user management , call statistics
4) What are the procedures for licensing?
You should be talking to your local PTC VAR or PTC Sales person about that.
FYI, there's a dedicated Vuforia Chalk community forum that you can access here.
