Visibility Measurement Method Design Competition shows students ability in application of information technology
(7 July 2012)

 

 

 

 
  Winners of the "Visibility Measurement Method Design Competition", an event jointly organised by the Hong Kong Observatory and the Faculty of Engineering of the University of Hong Kong (HKU), were announced at an award presentation ceremony today (July 7) at the Rayson Huang Theatre of HKU.

Visibility is influenced by factors such as rain, fog and haze, and is closely related to our daily life, especially on days with low visibility when navigation safety of aircraft and ships may be threatened. The objective of this first-ever competition in Hong Kong is to enhance the knowledge and understanding of engineering and meteorology among primary and secondary school students. The competition is funded by HKU's Knowledge Exchange Fund, and supported by the Hong Kong Meteorological Society and the Community Weather Information Network (Co-WIN).

Despite the technical challenges, responses to the competition were very enthusiastic. Over 140 teachers and students from Primary 4 to Form 6 of 16 schools formed 26 teams to compete for awards in the Junior and Senior categories. Different kinds of methodology were presented, ranging from simply identifying profiles of buildings in photographs through naked eyes, to using computer programmes to analyse multiple landmarks for automated visibility estimation. The entries fully demonstrated the students' ability in meteorological measurements and in the application of information technology.

At the award presentation, Professor Norman Tien, Dean of the Faculty of Engineering of HKU, commended students' innovation in producing a wide range of methods for measuring visibility. In the course of development works, computer programming, meticulous designs and testing, software and hardware integration, and well-prepared presentation of their final output all suggested that the students would be prospective engineers and scientists of the future.

To enhance the participants' understanding of the various methods to measure visibility, the Observatory and HKU jointly organised a series of talks, workshops and visits early this year to enable students to get familiarised with the subject and to produce effective designs. Mr Edwin Lai, the Acting Assistant Director of the Observatory, was most impressed by the students' team spirit. "Over the past six months or so, students had to persevere with their outdoor visibility observations, and to cooperate with each other in combining skills in software programming and hardware tool design to devise innovative methods for visibility measurement. This process was not easy at all," he said.
