Re: [IxDA Discuss] Heuristic Evaluation Criteria for Physical Devices
You should take a look at the Ergonomic criteria for human-computer interaction from Bastien and Scapin. http://www.inria.fr/rrrt/rt-0156.html On Mon, Sep 29, 2008 at 11:24 AM, David Shaw [EMAIL PROTECTED] wrote: Thank you all who have replied to my post!

Re: [IxDA Discuss] Heuristic Evaluation Criteria for Physical Devices
That would depend on the type and purpose of the device being evaluated. Can you elaborate?

Re: [IxDA Discuss] Heuristic Evaluation Criteria for Physical Devices
Sure... we're investigating some peripheral devices to our product (medical measurement devices like a blood sugar meter, etc.). Our target is elderly 60-80 with some type of chronic condition. I didn't know if there was a list geared more towards physical interaction (maybe even ergonomics).

Re: [IxDA Discuss] Heuristic Evaluation Criteria for Physical Devices
David, Here's a link to a paper by Jiajie Zhang and others where they extend heuristic evaluation and task analysis a bit with ideas from distributed cognitive task theory (from earlier work by Zhang and Don Norman) for the medical device domain; e.g. they analyze infusion pump interfaces in the paper. There are newer papers by Zhang on his site, but many are pay-for-access such as ACM Portal. Zhang, J., Patel, V. L., Johnson, T. R., Chung, P., Turley, J. P. (2005). Evaluating and predicting patient safety for medical devices with integral information technology. In K. Henriksen, J. B. Battles, E. Marks D. I. Lewin (Eds.), Advances in Patient Safety: From Research to Implementation (pp. 323-336). Rockville, MD: Agency for Healthcare Research and Quality. Zhang's research publications page: http://acad88.sahs.uth.tmc.edu/research/research.htm PDF of the paper: http://www.ahrq.gov/downloads/pub/advances/vol2/Zhang.pdf Enjoy, Joel On Fri, Sep 26, 2008 at 1:19 PM, David Shaw [EMAIL PROTECTED] wrote: Sure... we're investigating some peripheral devices to our product (medical measurement devices like a blood sugar meter, etc.).

Re: [IxDA Discuss] Heuristic Evaluation Criteria for Physical Devices
David - You can apply most, if not all, of the same heuristic principles that you apply to a strictly UI analysis, but I would also integrate key physical ergonomic factors like reach and posture. Here's a quick description of those characterisitcs - Feedback - Identify where the user's access to sensory feedback (e.g. visual, tactile) is comprised Reach - Identify situations where the user's major limbs (arms, legs) and minor limbs (fingers) must over-extend in order to carry-out a task Clearance - Identify situations where the user's major limbs (arms, legs) and minor limbs (fingers) must function within a limited space, such as finger holes or a handle Posture - Identify situations where the user's overall body posture is deviated from neutral position, as well as deviations at key joints (e.g. shoulder, wrist) Strength - Identify situations where the user must apply excessive or prolonged force for movement or stability, relative to their strength capabilities For a little more context, see 5 Guidelines for Ergonomic Observations (focused on field observations, but applicable to heuristics) - http://tinyurl.com/4pzb3c . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
