Here is an interesting non game DS title coming up that supposedly helps people walk “better”. Duke Sariaie’s: Healthy Walking Navi teaches people the “Dukeswalk” system and instead of watching on DVD you can view the lessons while walking outside. The lessons are taught with animations and pictures on the DS’ top screen while Duke narrates. You can also use the Duke Timer mode to have him yellow out encouraging slogans while you’re out walking around. The package costs 4,200 yen ($35) and it comes out on May 15 in Japan. While no US publisher is going to pick this up, maybe some other company might borrow the idea of making Nintendo DS software with a virtual personal trainer.
