Running experiments from mobile devices

Dear Forum User(s), 

I am exploring the possibilities of using Psytoolkit in a new study. When I tried to run some of the experiments on a mobile phone, I ran into the problem that I could not start them because they require pressing "Space bar" for continuing to the actual experiment after the instructions. I have not found a way yet to get the keyboard on the screen when there is no text input entry (and I doubt if that would work anyway). 

Is there any advice on how I can proceed with this issue?

Thanks in advance. 

Best, 
Silvano
