Heart Sutra App
The Heart Sutra 心經 is an app that allows you to read and write the famous Buddhist Prajnaparamita Heart Sutra.
The act of writing and copying the sacred texts known as sutras is an old and quite significant aspect of everyday monastic practice for Buddhists in East Asia. The Heart Sutra, the shortest of these sutras, is one of the most popular in the Mahayana Buddhist canon.
This application allows anyone to participate in the act of studying and copying the Heart Sutra on the iPad. Use the app for meditation, recreation, or as the monks do (to gain spiritual merit).
I designed and coded this app myself in Objective-C as part of a larger art installation within my thesis in Visual Studies.
This app was the first application and exploration I had made programming natively with Objective-C. I designed the app to allow users without any prior fluency or familiarity to write characters in traditional Chinese.
At the time of creation, writing resources used primarily static image diagrams, so I borrowed from these patterns to create interactive tutorials for each character in the text. I took all 124 unique characters of the sutra (284 total), and produced images and coordinate information for each individual stroke and the direction it should be drawn. Some of this was achieved programatically, but the bulk of the vector graphics were created by hand. While the function of the drawing portion of the app was fairly basic, it also included some logic to ignore extraneous user input while drawing, the ability to undo or redo steps, and more.
