Usually the cooker senses the temperature and amount of unabsorbed water left (conductivity ? ai forgot the exact input but Technology Connections had an excelent video on youtube on rice cookers for those interested). That's enough to manage a temperature curve and predict the last 10~15min of cooking (mine shows a time only 15min before the end), and doesn't require much input from the user.
