Jitter Projects

Brush

Description

In this assignment, you will build a patch that allows an iSight to act as a paint brush. Instead of 'traditional' paint, you will sample your immediate surrounding for colour and texture.

Task

Watch this video

I/O Brush is a project from MIT's Things that Think Consortia. It is a Tangible User Interface that allows a person to paint using their environment for color, texture, and video.

Your job is to replicate this project using MAX/MSP. Note, you do not have to replicate the I/O brush. You can use the mouse to simulate its interaction (e.g. taking a snapshot and painting it on a window).

There are many possibilities for this assignment. Using your previous work, you can generate multimodal interfaces. For example, while sampling a colour you could use your voice to change some aspect of the sample. As well, you could use the velocity of the iSight input to alter the incoming image. Remember, like I/O Brush, you can sample not only static images but video (and even sounds!).

Some ideas for extra credit for this assignment:

• Discuss this with me during class.

Submission

Your assignment archive should include all files required to run your patch. Include a short plain text README file that contains:

• the names and email addresses of all group members
• instructions on how to use your patch
• a short description of your design
• non-obvious things you did (if any)
• if you did any extra credit work, be sure to tell us what you did

It is strongly recommended that you test your submission before sending it to us. If we cannot figure how to open your submission then you will get zero.

Be prepared to discuss your solution in the next lab.

Grading

The assignment will be graded on the following rough scale:

• 1.0 - exceptional work that clearly went above and beyond what was given on the exercise
• 2.0 - exercise was completed satisfactorily as per the assignment specification
• 3.0 - exercise was completed, but has some problems
• 4.0 - incomplete exercise
• 5.0 - little or no effort was put into the exercise

Late assignments will be graded with a penalty of 0.5 per 24 hour period after the due date.

The Projects

The projects and tasks are designed to help you through the various courses and materials that you'll have to deal with, and also to provide an active and practical element to what could otherwise become a rather dry and technical exercise. Tasks are small exercises - you may be asked to complete one or two per week. Projects are larger and carry a higher percentage of the mark. We will undertake two, three, four or more projects and tasks. The final project is usually an individual choice project, and will be worth significantly more than the others in terms of percentages in your portfolio. We will usually try to set aside a time to perform the projects in a public setting.
