Concepts and more concepts. Feel free to add if you come up with another.

St.Paddy's Day 2011 Decision Matrix Version 1

March 21, 2011 Decision Matrix, Version 2

March 21, 2011: Judy - comments on decision matrix From what I can tell at this point - there are 3 clusters of scores as follows (and numbers never lie!!):


 * Low scores (<1) |||||| RFID patch (0.25) ||  ||
 * ||  |||||| mail-in patch (0.125) ||   ||
 * ||  |||| hospital kiosk (0.143) ||   ||   ||
 * ||  |||||| credit card (0.393) ||   ||
 * Medium scores (1-1.4) |||||| desktop (1.25) ||  ||
 * ||  |||||||| implanted recliner (1.25) ||
 * ||  |||||| chair recliner (1.25) ||   ||
 * ||  |||||| gaming kiosk (1.375) ||   ||
 * ||  |||||||| PC peripheral (1.393) ||
 * ||  |||||| shirt (1.339) ||   ||
 * ||  |||||| chest strap (1.339) ||   ||
 * Higher scores (>1.4) |||||| handheld (1.768) ||  ||
 * ||  |||||| toothbrush (1.679) ||   ||
 * ||  |||||| TV remote (1.536) ||   ||
 * ||  |||||| console (1.607) ||   ||
 * ||  |||||| watch (1.643) ||   ||
 * ||  |||||| alarm clock (1.5) ||   ||
 * ||  |||||| waiting room (1.625) ||   ||
 * ||  |||||||| retail check-out (1.625) ||
 * ||  |||||| shower (1.725) ||   ||
 * ||  |||||| vehicle (?) ||   ||
 * ||  |||||| shower (1.725) ||   ||
 * ||  |||||| vehicle (?) ||   ||

It appears when looking at scores across the columns for consistency of our reasoning (or rater fatigue) - we had the highest variance on usability - which is also one of the highest weightings - so we may want to each check our scores on usability across the concepts.

One idea next is to look at those with high scores to see where they could be improved (which features were lowest ratings). We also shouldn't dismiss the medium ratings as some (like the chest strap) would be cheaper and easier to produce - and could benefit from some of the sub-concepts of other ideas to improve the scores. Another idea is to combine some of the concepts into a single concept that might be used in multiple locations (i.e. something in a small console that could work in the home, handheld, waiting room, at the retail check-out, in a vehicle, etc.).

Still another idea is to go back and think about our original design brief goals and target population and revisit the concepts as to which fits these the best - more for the discussion tomorrow.

Decision Matrix V3-March 22 2011

Decision Matrix V4-March 22 2011

March 22, 2011 - Decision matrix iteration, concept adjustments and hybrid concept

__Hand held__ - More rugged material that maintains lightweight characteristic - Redundant cleaning system (improves safety and maintainability) – automatic application of disinfectant along with disposable - Testing site is not exposed to open air between use –sealed - Has potential ability to interface with vehicle concept
 * Potential improvements in design iteration 2**

__Toothbrush__ - Improve communications by having a screen in the base unit / recharger or projection onto mirror/wall - Display talks and listens to individual and allows function/results choice - BP measurement via cue to squeeze toothbrush harder

__Vehicle__ - More rugged material and water repellent – weight less impactful since vehicle based - Increased temperature resistance to withstand summer height and winter cold - If durability on steering wheel is a concern, shift to being an add on device or add as a more secured device to the steering wheel - Improved maintainability by having mechanic/technician change components – downside is that may require certification for technicians (recall – concept is work based) - Counterpoint – docking station with handheld and ignition lockout – useable outside of vehicle – covers people that don’t work with driving, a vehicle - Maintainability challenge is who takes responsibility – employer or employee - After market purchase that is transferrable to all commercially - Screen – interface with other device – perhaps incorporates GPS capability – to allow information feedback - If purchased as a GPS unit – sync’s with steering wheel and has a different device for out of car use – eg docking station or steering wheel in other car

__Watch__ - Durability – caution with weight increase – - Could make cellular communication but still cannot see any more information due to limitations on the size of the watch face

__Waiting room based (check out, salon)__ - Addition of self-cleaning thing to improve maintainability and safety - Ability to have outer shell customized to the environment that it is used __Shower__ - Powered device from shower flow makes screen and associated things work - Customizability enabled by screen choice and out cover options to match with decor - Challenge – if power from shower head – can’t be used for people taking a bath or vice versa

__Hand held / portable base unit__ - Portable base unit that is transferable from home, work, waiting room and docks locally for power and vehicle lockout capability - Has ability for employer use through peripherals that can be used in a vehicle - Capable to be mounted in a portable stand, kiosk for stationary use - Has a display screen for user interaction – touch interface that can display multiple pieces of information simultaneously - Incorporates other daily use information – eg. GPS for vehicle, clock for information - Talks out with own cellular connection to allow those without cell phones to utilize - Incentives can be usage context based – eg. employers get discounts for setup, installation and medical benefits; how users can get extended cellular usage to use as see fit - Device powered from solar and when docked (USB or vehicle power) - Testing method same as others – does testing happen externally or within the base unit?
 * Common concept?**
 * CHALLENGE – Those in poor cellular reception area (includes vehicle use) how does the communication with the medical system happen? – stores data until area where reception occurs – eg. picks up in open wifi zone?? Or uploaded from home since portable??

For Thursday** – how to divide up the rest of the work - System and mechanical detail designs - Organization of wiki for write up / report - Some concept diagrams? Size, shape, etc - Research? Eg. needle and chip characteristics
