The requirements

Doppelmayr is without doubt the world's leading manufacturer of cable cars and gondolas.

Knowing our specialization in the field of Interactive Content, they asked us to develop an Augmented Reality (AR) app, through which they could show the final aspect of several urban cable car installation projects to the different people involved.

As usual, this software had to be versatile enough to allow future implementations in different locations.

Our approach

From the very first time, we had very clear that for an Augmented Reality project like this, focused on the visualization of large world-scale elements, we had to use a markerless approach, under SLAM (Simultaneous Localization and Mapping) techniques.

In this respect, Google's ARCore provided us with all the necessary functionality here, including intelligent ambient lighting functionality throughout the immersive experience.

In parallel with the software development, the process of generating low poly 3D models of the urban station, towers, lines and cabins was carried out.

Then we proceeded to apply PBR (Physically Based Rendering) materials to all those elements, which would allow us to simulate any aspect in a realistic way and in a compact format.

By its own subjective nature, any Augmented Reality development raises a series of challenges for the design of the user experience (UX).

Así, en el caso de este proyecto u otros similares, la clave radica en ayudar al usuario a ubicarse en el mundo real, para al mismo tiempo guiarle en cuanto a donde debe apuntar la cámara de su dispositivo móvil, en el momento de lanzar la experiencia, para que ésta se inicie y posteriormente se desarrolle de manera adecuada y coherente con el objetivo de la visualización.

Thus, in the case of this project or similar ones, the key lies in helping the user to place himself in the real world. In this respect, sensors incorporated into any modern smartphone or tablet, such as the GPS system and the compass, can provide very valuable information.
