In our workshops this week we explored the idea of Projection Mapping, what it is and how it can be used in various ways. Below is a rough diagram that explains how the concept works on a small scale:

This is a basic example of how images and video can be projected onto various types of architecture. The computer software (such as HeavyM and Madmapper) is used to create shapes, designs, animations etc. before being fed into a projector and displayed on a surface. Sound can also be integrated so that items will react to music for example.

What are the possible uses?

As of current, projection mapping seems to be used purely for artistic experiment and technological advances. However, it could potentially go on to be used for educational purposes such as in primary school classrooms. It could also be used for medical reasons such as benefiting people’s mental health, by using the software to create therapeutic sessions (providing it is linked with professional methods of medical procedure). Industries may also benefit from this software as it will allow them to advertise their products in a new and innovative design; simultaneously being able to reach out easily to their target audience.

Disadvantages

Although projection mapping has its advantages, it also has its weak points. There are typical issues of health and safety which could affect people with photosensitive eyesight for example. It could also be dangerous in creating a distraction on buildings to traffic, aircraft and even pedestrians. The technology itself is also currently limited in terms of the types of surfaces it can be projected onto, as well as its visual quality.

Use in own project

For my personal project, projection mapping could be useful in enhancing the visuals used in the video. It would allow me to display my inner thoughts in a creative manner, for example showing phrases and images onto a brick wall as I walk past.
