There can some info be found in sessionprops device.userAgent and device.type To know if you are on a windows/browser or an andorid or something But other then that there isnt really a way to detect if you are a touchscreen (that i know off) from perspective. And you cant change it. entering chrome debug mode can be done with ctrl +shit +i followed by ctrl+shift+m But that proabbly not what you need xd ---

Doesnt seem like there is a surefire way to find out, why do you need it tho? If you expect touch and mouse events you should program them both anyway? ---
