TCRT1000 – Reflective Optical Sensor
Manufactured by Vishay Semiconductors
I ordered it from Mouser

Although, I am not convinced about the code they are using or the schematic… my schematic is working . This is probably NOT the most reliable pulse reader, but since I am not looking for high-fidelity in my project, this will do just fine.

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.

Designer/Artist + Co-Creation

With the advent of new technologies and the rapid dissemination and accessibility of information, artists and designers develop increasingly sophisticated ways of thinking about the world in visual forms and of approaching open-ended questions or specific problems in new and exciting ways. It seems that design and art now represent blurred categorizations: artists and designers grow more apt at interchanging roles and are increasingly willing to collaborate and co-create.

TSL230R Light to Frequency Converter

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'.

An Introduction to Usability (continued…) – Patrick Jordan

Designing for usability is a user-centered approach to design. Jordan lays out the different considerations to keep in mind during the design process and proposes a set of methods (some empirical, others non-empirical) that can be used as testing tools and discusses the advantages and disadvantages that come with each method. His writing allows designers to understand better that there are different ways of testing users and that some styles are more appropriate depending on the content of tasks involved in using a given product or interface and its relation to a demographic/technographic target audience.

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.

‘The Changing Sites of Value’

As part of The Internet as Playground and Factory, a conference series on the politics of digital media organised by Eugene Lang College The New School for Liberal Arts, Patricia Ticineto Clough, Orit Halpern, and Melissa Gregg introduced their individual areas of research and idiosyncratic takes on the notion of 'affect' and its evolution in meaning today as a result of technological progress.
