If you take the bus or the MTR to school and work every day, you will have noticed an interesting phenomenon. Everyone is obsessed with their own portable electronic devices. Electronic devices have become essential to passengers because of the blooming applications and growing popularity of portable electronic devices in town. Smartphones and portable computers not only entertain everyone but also give access to information anytime and anywhere during the short journey to work and school. As an electronic engineer, I am 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.
