The user uses the cane to take a walk outside. When back home, the cane automatically connect itself to the user home's wifi to transmit the datas collected during the walk to the high value service. Those datas gives information on the waking speed, the effort, etc. The high value service will synchronize the datas from the cane and other services (e.g: his calendar) or even other connected object (e.g: clothes with a heart-rate sensor). This synchronization change the initial temporal reference of the sensors to a discret reference more interesting to study.

Example: Synchronization with the user's calendar to highlight the improvement of the walk during an appointement with a physiotherapist.

Other example: Synchronization with the can itself to compare the distance between two steps and the pressure measured by the cane.

• GPS | Reseller link | Gotronic : 25523 | Technical Documentation

Datas are sent from the cane on a regular interval of 1 second.
We send all the datas at once, following this scheme :
altitude/latitude/longitude/heading/velocity/accelerationX/accelerationY/accelerationZ/compasX/compasY/compasZ/gyroX/gyroY/gyroZ/load
We choose to use this scheme because it is less bandwith consuming and easier to put in a file.

The high added value service has the following features :

• Route drawing : based on the gps positions, the walked route is traced on a google earth map.https://www.dropbox.com/s/si4iygoa2zjg5e9/kml%2Bcompteur_de_temps2.png
• Stability detector : If the user shakes too much, it will triger an alert (a sound in our configuration)https://www.dropbox.com/s/n4s5s9wu3hkxgir/stabilite2.png
• Effort measure : combined to an heart-rate sensor, it calculate the effort the user put into walking.https://www.dropbox.com/s/2qjpwvo8vv1f43m/Mesure_effort2.png
• Walking time : measure the time spent walking (combined with the route drawing)https://www.dropbox.com/s/si4iygoa2zjg5e9/kml%2Bcompteur_de_temps2.png
• fall notification : if the cane fall and another object detects the user has fallen, it will trigger an alert (a sound in our case)https://www.dropbox.com/s/pe6n3ydqslzks82/detecteur_tomber2.png
• Pressure measure : measure the pressure excerced by the user and if its above a treshold it will trigger an alert https://www.dropbox.com/s/tdvdidc0urkvkcr/detecteur_force2.png

1. Configure the internet connection of the phidget
2. Deploy the SharpWCompContainer under /root/UbikwanCannobi
3. Deploy the Ubikwan.wcc container on the phidget file system under /root/UbikwanCannobi
4. Deploy the required beans on the phidget file system under /root/UbikwanCannobi/Beans
5. Put the run.sh (https://www.dropbox.com/s/pisdm0an6iyaeyh/run.sh) script into /root/UbikwanCannobi/SharpWCompContainer/
6. Execute this command : “/root/UbikwanCannobi/SharpWCompContainer/run.sh”
7. (optionnal)Configure the initab to execute the previous command automatically after booting by adding the following line at the end of /etc/inittab :

“unci:2345:respawn:sh /root/UbikwanCannobi/SharpWCompContainer/run.sh (https://www.dropbox.com/s/0sih5orgoq058ux/inittab)

1. Launch WComp
2. Create a new container
3. Import the file : HV_final.wcc
4. Bind this container to UPNP
5. Create a proxy of this container
6. Create a proxy of the phidget service
7. Create a new container
8. Add the two previously created proxy
9. Link the stringevent event of the phidget proxy to stringmethod method of service proxy

After receiving the object, we had few problems while integrating the components. Indeed, there is only the load sensor and the Phidget platform that have a location to be put on the cane. The GPS and the spatial interface did not have their own location. Maybe a lack of communication with our contact in Reims caused this problem. Otherwise, some components were well thought such as the phidget container and the space for the pressure sensor, but the dimensions were too small to really fit those components.

By adding a heart-rate sensor to the cane, the measure of effort would be more accurate. Adding screens on the cane to help the user track his efforts while he is walking, would more likely make him actually use the cane.

Changing the format of the values sent through the service into a more readable format (e.g: JSON) will make the the usage of this service by other more easier. Stocking the different values of the sensors while the cane isn't connected to the wifi, will make the cane more useful because it often occured the cane isn't connected to a network at all while walking. And when the cane is connected back to the network, it will push all the datas collected to the different services.

Thanks to the collected data written in files, it could be possible to build a collaborative map showing the places that are not very stable for cane users.
