Hazard Perception Test now available for download

It was a bit of challenging project. But very interesting at the same time. Apple doesn’t provide many APIs to control the way a movie is played on iPhone. Considering this limitation I was postponing to develop Hazard Perception Test iPhone app for quite a long time. But finally its here. It took quite a long time than usual as I wanted to make the app just perfect.

The development approach I took this time was also different than my previous apps. I spent quite a lot time understanding how Hazard Perception Test works and how to model it into an iPhone app. I spent few hundred pounds buying original HPT videos from DSA and studied them.

After that I created several sketches to visualize how the app works. Meantime I was also doing several POCs to check if the particular feature is achievable using iPhone SDK. Later photoshop mockups were created to get the exact look and feel of the app.

Fortunately I ran into iPhonedevcamp and got a chance to demonstrate the prototype of the app I exclusively created for iPhonedevcamp. After I was satisfied with all the elements of the app I started actual coding. This was a great lesson re-learned that if all the aspects of the app are in place its a lot easier to code.

Here is the official iTunes description of the app.

The Hazard Perception Test comes to iPhone (and iPod touch).

Practice your hazard perception test with the video clips produced by Driving Standards Agency.

For video demo please follow this link.


We have included total 9 clips in the app which are –

1. Introduction to Hazard Perception Test
2. Watch for the pedestrian crossing the road.
3. Watch for the cyclist emerging from junction.
4. Watch for the pedestrian crossing the road, running for the bus on the right hand side.
5. Act promptly when a policeman or lollipop man or traffic warden stops you.
6. Watch for the kid riding the bicycle crossing the road.
7. Watch out for the vehicle emerging from junction.
8. Watch for the pedestrians crossing the road.
9. Watch for the vehicle emerging from the right.

The app has been designed carefully to replicate the same experience you will have in the real test. When in test mode, tap on the screen when you identify the hazard. The sooner you identify the hazard the more marks you get. The maximum marks being five and minimum would be zero.

The app also shows you the best and the worst score for each clip. Of course, you can reset the scores from settings screen.

If you want to know whats going to happen in the clip, you can turn on the “Clue” from settings screen and the clue will be shown right below the description of the clip.
