The Ashram is situated next to the Sabarmati river, and has many iconic, historic buildings. The installation called a ViRaasat installation is housed in a kiosk of size 8 ft X 4 ft X 9 ft and is composed of the following:

  • A Table to place the 3D fabricated model. In “ViRaasat Sabarmati Ashram”, the model placed on the table is of Hriday Kunj, Gandhiji’s home and office at the Sabarmati Ashram. It shows the different rooms and even some of Gandhiji’s possessions.
  • A Screen behind the table to project the Virtual Walk-through of the Sabarmati Ashram, interactively controlled through a Game Controller and a Tablet.
  • Projectors for projection on the model and the screen.
  • A Graphics workstation to render the Models and run the computer graphics software.

Users can interactively and virtually explore the Sabarmati Ashram using the game controller. They can also watch a guided virtual tour of the Ashram.

3D printed models of Gandhiji’s Utensils with an AR experience showcasing his experiments with food, his changing food habits over time and the science behind his food choices.Gandhiji conducted many experiments with food – these were scientific and well researched.  He kept a food diary in which he carefully recorded everything he ate and everything he felt. He never permanently gave up cooked food, but grew more inclined towards uncooked and organic food over time. Through an augmentation over 3D printed models of his utensils, the AR experience here tells the story of how his meals changed over time.

Users can download and install the app “Digital Gandhi Gyan Vigyan” from the Google Play store on their Android Smartphones to experience the AR over the Utensils.

Gandhiji was a prolific writer. He believed in the importance of communicating through letters. Throughout his life, he wrote letters to his family, friends, associates, national and international leaders; wrote in many languages that he knew; and wrote about topics close to his heart, expressing his deepest thoughts. Three of his letters are shown in this exhibit augmented by an AR experience through the mobile AR app “Digital Gandhi Gyan Vigyan”, to be downloaded from the Google play store.

  1. Gandhiji’s Travels AR Experience

This AR experience shows some locations and their connection with Mahatma Gandhi.  A Physical map of India is shown in this exhibit augmented byan AR experience through the mobile AR app “Digital Gandhi Gyan Vigyan”, to be downloaded from the Google play store.

  1. 3D Printed Gandhi Mementos (Statue and Signatures) augmented with an AR App.

One of the mementos is a 3D printed statue of Mahatma Gandhi in a walking posture with a 3D printed model of his signature in English. The replica is made by using a 3D scan model of the Statue of Mahatma Gandhi located at the entrance of the Canadian Museum for Human Rights in Winnipeg, Manitoba. The original sculpture was created by renowned Indian sculptor Ram Vanji Sutar. This sculpture exemplifies Mahatma Gandhi’s ideals of peace, justice, simplicity, minimalism and relentless action-oriented determination to achieve his goals – one of them being the independence of India. The replica is 3D printed in PLA, a bio-degradable plastic material, using additive manufacturing.

The smaller memento is a 3D printed replica of the English signatures of Mahatma Gandhi along with a line drawing of him in a walking posture.

Both these mementos comewith an Augmented Reality app called Digital GandhiAkar PrakaAR, which can be downloaded from Google Play Store and used by starting the app and pointing the camera of an android device (phone or tablet) at the Gandhi statue/signature. The Hindi phrase Akar Prakar  means “Dimensions”, and this app provides an insight into the different dimensions of Mahatma Gandhi’s life and teachings.
