Torch How-To: Prototyping a Mobile AR Wayfinding App With Torch AR
An Easy-to-Follow Step-by-Step Recipe For App Designers
This article is based on a post explaining how anyone can build a wayfinding prototype in Torch.
There is no coding or special knowledge required. All you need is a iPhone (7 or newer) or iPad (Pro or 2017+) and Torch AR.
The experience demonstrates an app that leads the user from the front lobby of our building to our office, navigating stairs, two right turns, and a left turn, and covering about 150 feet total.
I recorded this all in one take on an iPad and in one project using just Torch (e.g. no outside special effects or video editing software or cloud anchors.)
I used two 3D assets — the robot guide and dancing storm troopers — and seven variations of the same 2D asset including a welcome card, the checkpoint cards, the bike room card, and the party found card showing you have arrived at our office. Depending on your own environment, you’ll need more or less checkpoint cards.
I chose the flying robot from Sketchfab because I knew it could be placed imprecisely without looking strange. It could float. It also afforded me some flexibility since it had a “front” and a “back.” I could use this orientation to give the guide personality and indicate when it was waiting (facing the camera) and guiding (facing away and moving). The toggle for this is simple to set up too.
I built the text cards in Illustrator. I then exported the artboards as 1024 x 512 PNG’s to Google Drive where I could import them into Torch using the Object Drawer →Browse feature.
The storm trooper model is included at the end as surprise/reward for following experience to the end. I used it because it is animated and can capture attention from far away. Really anything fun or interesting would do.
