What is Projection Mapping?
Projection Mapping also called as Video Mapping or “Spatial Augmented Reality” is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection. These objects or displays can be complex industrial landscapes, such as buildings, indoor objects or theatrical stages. Projection Mapping uses everyday video projectors, but instead of projecting on a flat screen, the light is mapped onto any surface, turning common objects of any 3D shape into interactive displays. Projection mapping can be used for advertising, live concerts, theater, gaming, computing, decoration and anything else you can think of. This kind of mapping can be used for mapping the infrastructure and pollution, traffic congestion of a location.
Projection mapping is an art of transforming anything into a screen. Some of the example of projection mapping are:
- Bloom: Established in the year 1947, to provide a platform for the flowering of human spirit in the aftermath of the second world war, the Edinburgh International Festival celebrated its 70th anniversary in 2017. To mark the occasion, 59 productions conceived an opening event that transformed the whole of St Andrew square into a magical night garden and saw building burst into life in a floral explosion of color, texture and sound. Bloom ran for two nights at the start of the festival, from 10pm to midnight on a 20-minute loop, allowing the audience to enjoy the spectacle at their own pace.
- Interconnection: The winner of both the Jury’s Choice and People’s Choice awards at the 2016 iMapp Bucharest competition, Interconnection transformed the Palace of Parliament in Bucharest, Romania, into a psychotropic exploration of the interconnectedness of all things. Created by Limelight 3D Projection Mapping, it draws inspiration from contemporary visionary art and architecture, sacred geometry, physics and chemistry, and mixes them all up into a properly mind-altering five-minute trip.
- O2’s wear the rose: In September 2015, the O2 joined forces with projection artworks to create the world’s largest projection mapping projects to celebrate the Rugby world cup. Using 68 projectors and more than 122 moving head light fixtures the roof of the venue was transformed into the English rose emblem.
- 3D projection Mapping on India Gate: Was initiated by the Ministry of Tourism for promoting the Clean India Campaign. The display depicted the history of India, including the battles fought to protect the country’s sovereignty. This projection was used to send a message to people to stop littering and lend a helping hand to preserve India’s National heritage and pride.
Some of the applications of Projection Mapping includes:
- Augmented Reality: projection mapping technologies help in interactions between human and computer, human and human as well as human and machine.
- For human and computer interaction: a wearable device was developed in which the user can interact with graphical information projected onto nearby surfaces including the palm by touching it.
- For human and human communication: a tabletop system was developed and the user can browse through their classified information by casting their shadows on the table top while sharing graphical information in non-shadow areas.
- For human and machine interaction: a hand interface was developed in which a user can visually extend his hand by projection. E.g. while sitting on a chair the user can use the extended hand to tell a home service robot within a specific distance to do work based on the necessity.
- Clinical application of the projection mapping: Indocyanine green fluorescent image guided surgery was developed to identify primary and metastatic nodules of various malignancies. A novel projection mapping device was developed that can cast the real time fluorescent image onto the surface of the targeted organ.
Using projection mapping a person can create a visual experience that can be projected onto any surface so that it brings out a clearer picture of the project. This kind of mapping is transforming the healthcare and technology sectors and it helps them in building a better, secured future for all. Projection mapping is a terrific way to build visual experiences that can be enjoyed by a large group of people.
