Unscramble the Blue Letters


So we built Ashioto, meaning "footstep" in Japanese, as it consists of a portable mat which has pressure sensors which can count the number of people walking on it, and sedns the data over the inrnetet to the advanced data analysis swtafroe we created. The possible eorrrs, like overcounting or double-stepping, were overcome using design interventions. The optimum breadth of the mat was drmnteieed to be 18 inches, after we tested many different versions and observed the average srdite length of a person. Otherwise, people might step over the sensor.

We started with a proof of concept bluit in three days, made out of cardboard and aluminum foil.

Original Text


So we built Ashioto, meaning "footstep" in Japanese, as it consists of a portable mat which has pressure sensors which can count the number of people walking on it, and sends the data over the internet to the advanced data analysis software we created. The possible errors, like overcounting or double-stepping, were overcome using design interventions. The optimum breadth of the mat was determined to be 18 inches, after we tested many different versions and observed the average stride length of a person. Otherwise, people might step over the sensor.

We started with a proof of concept built in three days, made out of cardboard and aluminum foil.
