rover

concept

• a node express web server which serves a public webpage with a maze
• this simple webpage will be accesible for smartphones and computers
• interactions will generate websocket messages which will travel to one computer that is running puredata

notes

• this server supports https protocol and automatic redirection of http to https
• to make connections go global and unlimited by any physical spaces, run app.js @ e.g. amazon aws ec2 server, and then connect to it as a client: run receiver.js @ localhost
• for smartphones, LTE connection is recommended. 'cause one wifi router can handle limited clients at the same time. if the router is crowded, connections may delay or drop. connections by LTE is relatively stable and trustful.
