Armed with only a GPS and an Octopus card, students spent three hours travelling round the city to find clues leading to the final destination.
It wasn't The Amazing Race; it was part of the celebrations for the 150th anniversary of the World Telecommunication and Information Society Day.
The Communications Association of Hong Kong (CAHK) organised several activities in line with the International Telecommunication Union's theme "Telecommunications and ICTs: drivers of innovation" to teach students about the importance of information and communication technology (ICT) in our daily lives, and spark interest in joining the industry.
And they're off!
Activities included a photo creation competition based on smart living, and a custom phone case design contest, but the main event was the geocaching game, in which 40 teams of students had to go around town, completing a list of challenges.
All the teams received their first clue and challenge at Polytechnic University. Students could go on to the next checkpoint only once they'd completed their challenge.
Many of them were excited at the chance to explore new places around town, from Hong Kong's renowned universities to shopping malls, all the way to the Avenue of Stars in Tsim Sha Tsui, where they took selfies with the statue of the legendary Bruce Lee.
But unlike like The Amazing Race, the roughly 200 students each had an electronic buddy to assist them throughout their journeys: a GPS. It helped the team from PAOC Ka Chi Secondary School find military barracks on Nathan Road for their first challenge. The barracks were in Kowloon Park.
"No one on our team knew Kowloon Park had military barracks! Without the GPS, we would have been completely lost," said Amanpreet Kaur, one of the team members.
A big part of our lives
CAHK chairman Stephen Ho (pictured above) hopes these activities will help people understand the importance of information and communication technology in our lives. He believes information and communication technologies have shaped our lives and made them easier in recent decades.
"Doing business has become a lot more efficient and effective. Thirty years ago, most of us didn't have credit cards, and we had to finance our transactions by cash. But now, all you need is a plastic card, your signature, and the transaction is good to go! Not to mention, the fact that you have a month's time to settle your payments." he says.
Many other aspects of our daily lives have also seen vast improvements, including education and entertainment. "You can do almost anything with your smartphone! It's almost like having an encyclopaedia at your fingertips, or better yet, the world in your hands," he said.
Used to simplicity
Sometimes technology is so standard that we start taking it for granted, and it's only when faced with a new challenge that we become aware of how easy things are.
"Information and communication technologies are in so many aspects of our lives, sometimes I don't even realise," says 16-year-old Komal Ashfaq. "I've always used email to stay in touch with people. But few months back, I was asked to post a letter, and I didn't know how to do it!"
Komal had trouble recalling the format required for writing addresses, and stamps were a mystery. "At first, I actually forgot we needed stamps, and when I found out we did, I had trouble finding the right one. Not to mention, further confusion about which side of the envelope I should put the stamp on!"
Now she appreciates the ease of communication she and her friends have, saying: "When you need to contact someone on Whatsapp, all you have to do is press send. But when it comes to letter writing, you really have to go through a long, confusing process before that letter reaches the other person."
Anyone can develop tech
Ho sees a bright future for information and communication technology as it plays a very important role in innovation today.
"The development of technology has made innovation a lot easier over the past few decades, as people are given the freedom to build on their ideas with the help of software," he says.
He hopes the activities such as the ICT event will help young people take an interest in innovation, and make them realise that they are not only users, but can be innovators, too.
They certainly gave a new perspective to 16-year-old Marium Malik. She has now decided she should keep her options to the industry open.
"I always thought the industry would be very boring and not challenging, and I'd only get to do tasks like calculations and programming." she says, but the day's activities changed her outlook on what the industry could offer.
"I use technology in so many aspects of my life: for basic needs, education, entertainment, and to stay connected with the world. With such a vast scope, I believe I may be able to find my interest in the field, and become a successful innovator one day."
