You can use InputString[] to get the input as a string, parse it (ToExpression, especially its third argument will be used.  Please see the docs.  Also see StringSplit)

However, I'd suggest using InputField instead which works with Dynamic technology.  To make it read a string, use InputField[x, String].  A similar issue has been discussed here:
