Study Finds Pokéwalker More Accurate Than Other Pedometers: "
Nintendo’s HeartGold and SoulSilver Pokémon Pokéwalker, is a more accurate pedometer than regular pedometers, according to Lorraine Lanningham-Foster (Iowa State University).
Image via WikipediaAt the 2011 Experimental Biology conference in DC, she presented the accuracies of several pedometers of children and adults while walking on a treadmill at four different speeds.
Kotaku points out that the research isn’t being funded by Nintendo, but by Iowa State’s Nutrition and Wellness Research Center.
Participants: 22 children, 8 adults
Walking speeds: (1.5, 1.8, 2.1, and 2.5 mph for children, 1.5, 2, 2.5, and 3 mph for adults)
Results: With the Pokewalker, the faster the treadmill speeds = lower amount of error. However, looking at the mean percent error is a little disconcerting (32% ± 23 at 1.5 mph, 12% ± 20 at 1.8 mph, 3.2% ± 5.6 at 2.1 mph, and 2.4% ± 4.2 at 2.5 mph).
Points to Ponder (P2P)
- Something I'll ask Lorraine is the placement of the PokeWalker. I know it comes with a belt clip but I also know alot of kids put it in their pocket or back pack.
- It would also be interesting to see the results of free-living assessments or longer periods of time.
- Is the Pokewalker a piezoelectric device or an accelerometer?
- The SenseWear Armband actually uses an accelerometer to assess steps and is placed on the back of the upper arm. Given the discrepancies in the placement of each product - how does this impact the findings?
