The SMS contains a link to where the person has fallen on google maps. There are three ways a location can be determined via GPS, cell-tower triangluation or using Wi-Fi networks. It will use the most accurate technique available to locate where the person has fallen.
Fall Monitor uses a clever algorithm in order to detect a fall. It must be noted there is a delay of ten seconds before the alert goes off. This is the still state. The alert only activates if the user has not moved for ten seconds after the fall. This is used to prevent false alarms, as the user may get up again after the fall.
The alert then gives the user forty seconds to cancel the alert in case of a false alarm.
Key Features competitors don't have:
Three different location techniques in order to detect the fall location.
Works while the screen is off.
Accesses phonebook for contacts.
Works while the phone is locked.
Fall monitor service starts automatically when you turn on the phone.
Multiple emergency contacts supported.
Direct rapid feedback from developer (me!) for any problems that may be encountered.
Since I am a solo developer, I vacate all the roles in the development process. Please feel free to give me feedback on the app and in particular how it could be improved upon. Bug reports would be greatly appreciated also, if any bugs exist. You can contact me via email (ericcurtin1990 [at] gmail.com), and I will try my best to respond within twenty-four hours. All emails will be responded to.
iFall listens to the phones accelerometer and tries to detect when a fall has occurred. There are three stages to a fall: 1) the fall, 2) impact with the ground, 3) a long lie indicating the user is injured and needs assistant.
In the case a fall is detected the user is issued a prompt. This prompt is to the give users a change to reduce false positives. If the alert has timed out without user response, their emergency contact (set in alert settings menu) is automatically called to further evaluate the situation.
