28/Jan/2016, 9-16h: Project development
29/Jan/2016, 9-16h: Project development and presentation

The course is focused on the generative aspects of multimedia design and the authoring process, interaction design and the control of media elements in interactive projects. Students will experiment with a broad range of media elements with an emphasis on controlling media behavior through code. Special emphasis will be given to crossings between sound and image: sound visualisation; sonification; audiovisual composition; visual music; etc. Continue reading

project critique

Please write a critique of your project (extended deadline: June 9th, no latecomers!). The critique should include a summary of your project, a comparison of the initial idea and the implemented project, the future development. Revisit your work and be critical towards your project: What was great and what could have been better? What is your main learning experience? What will you do differently in your next project?

The report should be at least 1A4 and delivered to me in pdf format.

Project Proposals

On 19 May you will present your project proposals for Multitouch Interaction 2015.

Project requirements:

The project can be any application that involves multitouch interaction.
The projects “examples/iOS” in openFrameworks can be used for inspiration.
Also check other oF resources, such as the oF Forum. The Forum is very rich on information and resources, and has a dedicates iOS section.
In your project, you will probably have to mix parts of these exercises, and the exercises done during the classes.
How to present the concept:

Present your concept using wireframes (see links below), and a project description (a summary, 2-3 paragraphs of text). If your wireframes are low-fidelity (see difference to high-fidelity in Wikipedia link below), you should convey a visual character for the project, for example using mood boards: – there are many more resources on the web and mobile regarding mood boards)
Then publish all these elements (description, high-fidelity wireframes, or low-fidelity wireframes + mood board) in the course blog. Registration is now open but will be closed as soon as all students are in (preventing spammers).

Please be realistic regarding what you plan to present on 26 May.
In the project description, explain how far the project will be implemented by 26 May.
In class you will present your project idea for 5min after which we will take 5min per project to discuss feasibility of the projects and the steps to take to implement your idea by 26 May.
After the final project presentation on 26 May you will have one week to write a reflection on your project (more info on this will appear here soon).

making the simulator work

Here is a hack to make the simulator work with the current version of OpenFrameworks and Xcode 6. Add the following piece of code in the very end of (after the curly bracket of int main()</ closes.

extern "C"{
    size_t fwrite$UNIX2003( const void *a, size_t b, size_t c, FILE *d )
        return fwrite(a, b, c, d);
    char* strerror$UNIX2003( int errnum )
        return strerror(errnum);
    time_t mktime$UNIX2003(struct tm * a)
        return mktime(a);
    double strtod$UNIX2003(const char * a, char ** b) {
        return strtod(a, b);

The code redirects a number of functions to work with XCode 6 simulators.

enable Retina support

To enable retina support in your project go to replace the standard line:



ofAppiOSWindow * iOSWindow = new ofAppiOSWindow();
ofSetupOpenGL(iOSWindow, 1024, 768, OF_FULLSCREEN);
