Jed Looker | Carleton University (original) (raw)
Jed holds a B.A. (Hons) Graphic Design with the University of Hertfordshire and a Graphic Design Diploma with Algonquin College. He is currently studying towards a Master of Design (MDes) with the School of Industrial Design at Carleton University.
Building on a foundation of visual communication, Jed focused his professional development on user-centred design. For 4 years he worked as an interaction designer for Espial, developing user interface prototypes for the company's line of TV set-top products. His passion for teaching–and an insatiable appetite for adventure–would then lead him to China, where he taught English for a year.
Returning to Canada Jed spent 2 years designing on-site showrooms and interactive floor plans for Avenue, an ad agency servicing the homebuilding market. He spent the next 6 years running his own studio, offering interaction design services to both private and public sectors.
For two years Jed was an IxDA Local Leader, during which time he helped organize professional speaking events in support of Ottawa's user experience community. He now teaches interaction design at Algonquin College, and has worked with his students to develop several applied research projects. One of them went on to take the top award at the Polytechnics Canada Student Applied Research Showcase.

After reviewing ergonomics literature we found the air tap appeared to be outside of known anthropometric and biomechanical limits and tolerances. Because the Hololens was unavailable for testing at the time of writing, the air tap was evaluated using methods that support general, observational data. The Rapid Entire Body Assessment (REBA), Rapid Upper Body Assessment (RULA) and Novel Ergonomic Postural Assessment (NERPA) methods were used to assess the gesture as observed in four videos. For all methods, higher scores suggested further investigation was required to avoid risk of developing musculoskeletal disorders. Although the neck trunk and leg portion of the REBA score was low, the arm and wrist portions gained more points. This was further reflected in overall high RULA and NERPA scores which focused more on the upper region of the body. Although these findings cannot be used to accurately assess whether the air tap suffers from poor ergonomics or puts the user at risk of developing musculoskeletal disorders, they do suggest the gesture might benefit from a more thorough investigation. This paper concludes by proposing future research into developing and validating an ergonomic framework designers and developers can use to develop 3D gestures.
