Description
The Department of Veterans Affairs, Pittsburgh VA Medical Center, is in need of Two android applications, physical exercise intervention and cognitive exercise intervention, for an android smartphone. The target smartphone is the Samsung Galaxy On5 (T-Mobile version). The new modules needed for this new research initiative will be built on the existing Android platform and tie in with the current system design being used in existing telemedicine applications. The contractor will work directly with government personnel on the design and development of the android applications.

Salient Characteristics Two android applications:
Essential/significant physical, functional, or performance characteristics:
Participants in the research program will be assigned to receive (1) physical exercise intervention alone, (2) cognitive exercise intervention alone, or (3) both physical exercise and cognitive exercise in combination.
- Physical exercise intervention requirements
The physical exercise intervention (i.e., bike program) will consist of a 5-minute warm-up phase, a 39-minute interval training phase, and a 5-minute cool-down phase with the bike set to the lowest resistance level for the entire session.
- All signals from the stationary bike will be checked at startup to ensure proper connections. If problems are detected, troubleshooting will occur.
- The application will check the signal from the stationary bike to ensure that the resistance level is set to the lowest level. If it is not, then the application will instruct the user to change it to the lowest level before starting the session.
- All session parameters (e.g., HR targets, length & number of intensity periods, timeouts) will be designed to be modifiable and loaded in at run-time so that changes can be made to these parameters without needing to change the code.
- A filtering and smoothing function for HR will be required to detect and prevent inaccurate signals from misrepresenting the actual HR used to determine exercise intensity. This function will continuously monitor HR to determine the fidelity of the HR signal. Outlier values will need to be filtered out to create a stable and accurate HR to assess the user’s intensity during exercise.
- The interval training phase alternates between 4-minute high-intensity periods and 3-minute low-intensity periods for a total of 39 minutes. There will be six total high-intensity periods and five total low-intensity periods. The number and length of these intensity levels need to be modifiable parameters that are loaded at run time.
