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.

Paper Prototyping: The Fast and Easy Way to Design and Refine User Interfaces – Carolyn Snyder
Carolyn Snyder proposes a definition of paper prototyping as 'a variation of usability testing where representative users [...] [interact] with a paper version of the interface that is manipulated by a person "playing computer" ' (italicized in original, p.4).
The aim of her book is to extend the practice of paper prototyping to a variety of HCI platforms for non-expert users to adopt as a practical tool for creating and testing their products during the development process.
Golan Levin
As a quest for expanding the vocabulary of social practices and of the object-subject relationship, emotional technology (smart, intelligent) simulates human behaviour and creative energy. It revisits the environment anew for new types of interactions and explorations.
Golan Levin is a software artist who creates screens and robotic objects that study sound, speech, movement, and gaze.
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 Backtalk of Self-Generated Sketches – Gabriela Goldschmidt
"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.
“Defining Goals and Concerns” and “Deciding Who Should Be Participants” – Joseph Dumas & Janice Redish
Before you begin testing it is important to set your primary evaluation goals and concerns. Once those have been defined, it will be possible to plan a usability test accordingly. Dumas & Redish raise the following processes: making choices among goals and concerns; moving from general concerns to specific ones; and understanding sources of goals and concerns.
