iFall: Android Application for Fall Monitoring and Response
Injuries due to falls are among the leading causes
of hospitalization in elderly persons, often resulting in a rapid
decline in functionality and death. Rapid response can improve
the patients outcome, but this is often lacking when the injured
person lives alone and the nature of the injury complicates
calling for help. This paper presents an alert system for
fall detection using common commercially available electronic
devices to both detect the fall and alert authorities. We use a
common Android-based smart phone with an integrated triaxial accelerometer.
Data from the accelerometer is evaluated
with several threshold based algorithms and position data to
determine a fall. The threshold is adaptive based on user
provided parameters such as: height, weight, and level of
activity. These variables also adapt to the unique movements
that a cellphone experiences as opposed to similar system which
require users to mount accelerometers to their chest or trunk.
If a fall is suspected a notiﬁcation is raised requiring the
user’s response. If the user does not respond, the system alerts
prespeciﬁed, social contacts with an informational messag e via
SMS. When a contact responds with an incoming call the system
commits an audible notiﬁcation, automatically answers the call,
and enables speakerphone. If a social contact conﬁrms a fall , an
appropriate emergency service is alerted. Our system provides
a realizable, cost effective solution to fall detection using a
simple graphical interface while not overwhelming the user
with uncomfortable sensors.

Frank was the initial student to start the mobile lab with Dr. Tyson. After working on the first project, iFall, he and Dr. Tyson designed the Mobile Programming course as FSU. The course is used as a training base to recruit new students into the lab. His thesis researches several medical related applications, including iFall. Frank then went on to implement the redesign of the “favorite contacts” for Android’s Ice Cream Sandwich at Google HQ in Mountain View, California. He currently acts as a tech lead in the lab getting infrastructure and project management tools setup. He has special focus on native Android coding and UI design.
