Ryan Ng - a final-year electronic engineering major - has created a smartphone application that might help visually-impaired people navigate around MTR stations easier.

He told RTHK that app can help a person find the nearest escalator and also know to which exit the escalator will lead to.

His invention is among the projects that are being highlighted at the City University which is showcasing the inventions of science and engineering students at a two-day exhibition.

Other concepts on display ranged from realistic training software for wheelchair users, to the development of a "hacking laboratory".
