Different between Zoho CRM Kiosk and Command Centre functionality

Different between Zoho CRM Kiosk and Command Centre functionality

Is there anyone who can tell me the difference between these two features available within zoho crm. I want to know what is the logic behind to build this kiosk functionality ? Because we have now blueprint , command centre and kiosk feature in crm so Isn't it too confusing for a user to choose between these three?

Also if there is any overview video available on zoho crm kiosk feature then please let me know
