In a report by Canadian Healthcare Technology, Edward Lamaire, PhD at the Ottawa Hospital Rehab Centre is spearheading a new app creation.
They are calling it WMMS (Wearable Mobility Monitoring System).
The premise is based on other wearable devices made specifically for the medical industry that would traditionally require a patient to have various monitors wired to their person in a somewhat ungainly and expensive fashion. These devices would monitor and record human movement, stature, speed, location etc.
But in this case, the idea is to use a BlackBerry 10 handset with all of its’ inherent sensors to do the work of the existing disparate devices thereby enabling the patient to have info gathered and stored whilst going about their normal lives and activities.
The mobile app records real-time data using the smartphone’s built-in sensors, including the magnetometer, accelerometer, gyroscopes and video camera. These data are used to drive our mobility classification software that identifies the type of movement, such as active, inactive, walking, sitting, lying, etc.
The video camera on a BlackBerry 10 phone plays an integral part of the solution as Dr. Lamaire explains…
With the addition of video clip analysis, where three-second video clips are captured at each change of activity, more detailed classifications can be made (for example, riding elevators, walking on uneven ground, or working in a kitchen). This information can be used to make decisions on treatment related to a physical disability or as an indicator of changes in mobility status for chronic diseases.
According to Dr. Lamaire, BlackBerry 10 provides the perfect platform for these kinds of critical applications, (but then we knew that didn’t we dear readers).
To capture critical information, all the sensors and tools need to be in sync. If the camera lags behind the software’s signal processing by just a few seconds, an important activity transition may pass without a video record. In this way, the speed and multitasking capabilities of the BlackBerry 10 operating system meet an important threshold. The internal sensors can record data at about 50 times per second, which allows us to make decisions based on real-time information.
Quite right good sir, go on!
For example, if the sensors detect an incline, such as a ramp or hill, the camera could record video that can be reviewed later to get more insight into the person’s movement. Was she walking on a grassy, uneven hill? How did she adjust her gait and posture? This context provides invaluable information about movement in areal environment, and helps us track recovery and adjust treatment.

But, as a taster you can see and download an app called “BAR” (Biomechanics Augmented Reality) that was created and submitted to BlackBerry World here.
The Biomechanics Augmented Reality(BAR) app uses the smartphone’s accelerometer and camera to superimpose a gravity reference grid and line (i.e., a plumb line) over the camera’s live video.
Since the grid is always oriented to gravity, the clinician has a repeatable reference frame when visually assessing posture and body orientation, such as during a wheelchair seating assessment or standing posture evaluation. By adding additional lines over the video that represent the phone’s orientation, the app can display live angles between the phone and the gravity line. This provides a quick tool for body angle measurement at the point of patient contact.
We are on the cusp of true mobile computing. With QNX, NantHealth, BlackBerry 10, and Chen at the helm I see a very bright and healthy future indeed.
