Devin Ketchum

I’m a lecturer in the Engineering and Computer Science departments at Cal Poly Humboldt. As a multidisciplinary engineer and proud Lenape, two-spirit professional, I bring a blend of technical expertise and human-centered design to my teaching. Family grounds me; I’m lucky to share life with a supportive partner and two wonderful kids who keep me inspired, curious, and creative.

Master of Science in Computer Engineering, December 2019

Virginia Polytechnic Institute and State University, Blacksburg, VA

• “The Use of the CAfFEINE Framework in a Step-by-Step Assembly Guide” - The purpose of this research is to explore using affect as an implicit feedback channel so that such mistakes would be easily corrected in real time. The CAfFEINE Framework, is a context-aware affective feedback loop in an intelligent environment. For this research, the focus will be on analyzing a user’s physiological response to the service provided by an intelligent environment. To test this feedback loop, an experiment was constructed using an on-screen UI, step-by-step assembly guide for a Tangram puzzle. To categorize the user’s response to the experiment, baseline readings were gathered for a user’s stressed and non-stressed state. The Paced Stroop Test and two other baseline tests were conducted to gather these two states. The data gathered in the baseline tests was then used to train a support vector machine to predict the user’s response to the Tangram experiment.
