Inspired by the success of Pokémon Go, a Belgian primary school headmaster has developed an online game for people to search for books instead of cartoon monsters, attracting tens of thousands of players in weeks.
The game, which marries a classic 20-year old franchise with augmented reality, allows players to walk around real-life neighborhoods while seeking virtual Pokemon game characters on their smartphone screens.
The multibillion dollar games industry has various user interfaces, such as mobile apps, servers and consoles. It remains a dynamic and profitable sector of the tech industry. Some games that have achieved widespread recognition include Minecraft, Angry Birds and Candy Crush.
