If you take bus or the MTR for school and work every day, you will find an interesting phenomenon recently. Everyone is obsessed with their own portable electronic devices. Electronic devices become essential to passengers, since the blooming application and growing popularity of portable electronic devices in town. MP3 players, smart phones and portable computers not only entertain everyone but also give the access to information anytime and anywhere during the short journey to work and school. As an electronic engineer, it would be so proud and happy to see my designed products being widely used in daily life. The design element of “people oriented” is always at the heart of my training, as an essential linkage between technology and user demand.
