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.

The Simplicity Shift – Scott Jenson
Scott Jenson defines 'feature blindness' as users being blinded by a feature list. He identifies the bottom-up approach of creating a user persona and a task scenario as more efficient than the top-down approach, in terms of organizing a commonsensical hierarchy of a product's features. The ideal visualization would be to 'tame' the feature list and prioritize features in accordance to a set of usage requirements and subsequent usage frequency.

“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.
