This is a first try at using TSL230R to measure HRV (Heart Rate Variability) levels. It will be used as part of a larger project to collect users’ heart rates and translate this data onto a mobile (potentially wearable) screen as a non-verbal messaging system that reveals a somewhat hidden state of ‘being’. The messages will be set to be sent according to the value range of the heart beats as dynamic visualizations (for the time being I will be using Processing). In addition to this, each message will have a specific time span and a specific ‘mood’ or ’emotion’ attached to it. To do this I will be using a second variable EEG: Electroencephalography. HRV and EEG are interesting values to juxtapose as they symbolically represent the physical, biological, and social connections existing between the heart and the brain. This second variable will add a level of randomness to the system, which will enable messages to have a wider visual scope.

“Evaluating Usability Throughout Design and Development” – Joseph Dumas & Janice Redish
Joseph Dumas & Janice Redish analyze the potential benefits of combining various evaluation methods as complementary tools for usability testing in the context of usability engineering.
How to Plan, Design, and Conduct Effective Tests – Jeffrey Rubin & Dana Chisnell
Testing has two main objectives: on the marketing level, it aims at improving sales; on a user-centered level, it aims at minimizing user frustrations and maximizing a product's usability. As the authors point out, testing goals inform the design of a product; those work in terms of the usefulness or relevance, learnability, efficiency, effectiveness, and satisfaction factors.
Armando Guiller
Armando Guiller is a mechanical engineer by training, and a growing artist by passion, and has won numerous honorary awards. His sculptural work has the ability to communicate with scientists, engineers and artists, as it involves craft, mathematical precision, and highly conceptual and philosophical investigations into spatial and perspectival associations. He uses both industrial (metal) and natural (wood) materials, which he treats himself with heavy machinery.

"The inventive process" is an iterative process of jotting down ideas in the form of language or graphic drawings and of modifying them, reevaluating them, editing them, and so on, to transform or perfect an initial concept or solution.
Don’t Make Me Think! A Common Sense Approach to Web Usability. – Steve Krug
Steve Krug explains how we can create better Websites if we just stop wasting time on useless debates within teams and engage in 'usability testing' early on in the development process. His book provides the antidote.
He distinguishes between designers and developers in what they consider to be a 'good' website design. Designers prefer pleasant layouts, whereas developers enjoy a good amount of features. This is also compared to the duality between commercial culture and craft culture. Which is a question of aesthetics versus usability. Ideally, we would want to have both.
