City University (CityU) students are making life easier with their inventions: a system to track missing trail-walkers and a handy device to computerise grocery shopping.
Keen hiker Ng Ka-ho from the department of electronic engineering was inspired by the off-duty police officer who is still missing after going hiking. He developed a monitoring system that utilises Global Positioning System (GPS) to allow hikers to identify their exact location on a mobile phone screen. Using a Bluetooth GPS receiver, a mobile phone supporting the Java application and Mr Ng's software, they can also preset a time to automatically send an SMS to a designated contact to indicate their location.
Computer science student Brian Chung Chun-hei created the Family Grocery Management System. Family members can create shopping lists on a computer or PDA and the system will suggest what to buy based on past shopping preferences. It will also issue a reminder to buy products that will soon be used up.
Undergraduate students from various departments at CityU developed 78 projects that addressed everyday needs. Their works were exhibited last week at the school.
