However, if you run when you move, your footprints will be displayed on the Oni's(it's) smartphone.
While you are the Oni, you will not receive any points for moving, so the Oni will need to move on to others as quickly as possible. Oni can be transferred to other players by approaching them.

Motivations / Problems
Therefore, if the patient wants to change the hospital or the doctor, or if the doctor in charge changes, it is difficult to refer to the past medical records.
I would like to solve this problem, so I focused on visualizing rehabilitation.
Interviewing to doctors, nurses and physical therapists
To learn more about the rehabilitation process and how it is recorded, I interviewed doctors, nurses and physical therapists who actually work there.
I also observed the actual rehabilitation process and asked them about any questions I found.
As a result, I found out that quantitative measurement of gait rehabilitation using a cane is not yet available, and that it requires expensive pressure gauge machines and a large space.

Prototyping
In order to actually test the issues that emerged from the interviews, I decided to create a prototype of an inexpensive, space-saving cane-shaped device and software for monitoring sensor values.
Hardware Prototyping
Sensors / Components
I attached an accelerometer to the cane device to measure posture, and a load cell to make sure the patient's weight was not too much on the cane.
3-axis accelerometer sensor x1
To sense the posture of gait.
load cell x1
To sense the weight to the cane.
Bluetooth module x1
To send all data to doctor's smartphone.
Battery
To make the cane work as a stand-alone device.
Software Prototyping
In the software, I made it possible to observe the data sent from the device in real time, and displayed the sensor values in a graph so that the doctors can evaluate whether the walking posture is bad or not. In addition, since it was difficult to tell when the timing was right from the graph itself, I made it possible to record a video at the same time, so that the actual walking of the patient could be seen in correspondence with the graph.

Organizing an event
At Asobousai, we prepared not only PetaPeta, but also a variety of contents that connect play and disaster prevention.
PetaPeta in Asobousai
However, not only the local residents but also the tourists do not know where to evacuate to in case of a tsunami.
Tourists naturally do not come to the area for disaster prevention, so it is very difficult to provide education adapted to the local community.
Therefore, PetaPeta hid the purpose of disaster prevention and designed an experience where people can learn about disaster prevention by simply playing the game.
The location is actually a tsunami evacuation building, and after the game is over, the player can look back through the spectator screen and simulate how panicked they were and how long it would take to evacuate, resulting in a learning experience.
Next Step
PetaPeta not only provides an opportunity to learn about disaster prevention, but I feel that it has unlimited potential as a content to learn something through gamification. In particular, I believe that PetaPeta can be used as a tourist resource to learn about the city, as it goes well with content that uses maps.
