cardiacrehab's Issues

Reconnect with Unity

If the Unity application loses connection with the patient application (not sure how this would happen), unity should be able to reconnect to the patient application.

Refresh access_token

Related to #22 . Once that issues is resolved, then need to test the system until the access_token expires then handle this event smoothly.

Patient should be able to request for connection

If the clincian starts the session without a patient, the patient should be able to request for connection at any point during the session.

Create a test UDP socket class

To test for effectiveness of UDP socket vs current TCP system, need a test class.

Add "animation" to handle + wheel

To make the turning look more realistic, add slight turn to the handle + wheel when turning is detected.

Create a mock client to represent the phone

Related to #15 . Need this for testing purposes.

Minimize (if not remove) packet loss

With old and new system, there are some packets being lost in transmission between the phone and the patient. Need to really test if the phone is failing to send the data or if the C# fails to receive the data or if the data is being lost in network somewhere?

Establish multiple patients to clinician connection 4

biodata + bike data + video + audio

Integrate iHealth devices

Be able to pull from iHealth cloud to get blood pressure data.

Insert note to database

Currently notes made during the sessions are not inserted to the db.
Not sure if this should be encrypted in database?

Create iHealth accounts

Related to #22 . Need 6 mock accounts and also store these account name and passwords into the db.

Establish single patient to clinician connection 3

biodata + bike data + video

** video should be implemented with UDP and jumboframe!

Establish multiple patients to clinician connection

biodata only

Two way connection between patient and phone

To increase the resistance when incline is detected from #14 , need to be able to send a flag to the phone to increase the resistance.

Encryption

Encrypt all transimtted data!
Need to research which encryption algorithm to use.

Doctor should be able to select patients to connect with

There should be an option for the clinician to accept/reject patients in PatientList UI. (In case a patient is at wrong session time..etc)

Establish multiple patients to clinician connection 3

biodata + bike data + video

Create Settings for patient side

Would be good to have:

• choice to have VR full screen without any video/stats
  (or be able to choose which one to show on UI)

Establish single patient to clinician connection

This should be done with biodata only.

Change network protocol to UDP between patient and unity

Currently used TCP is not necessary for transmitting data to unity...

This should be done for both bike data and the turning data...

Establish single patient to clinician connection 4

biodata + bikedata + video + audio

** audio should also be in UDP + jumboframe

Take out the dropdown menu in PatientList window

The dropdown menu doesn't serve any purpose and it complicates the code more. Take it out and set the max number of patients as 6.

Test with a proper web server

Currently, everything is tested with a primitive python web server. This system needs to be tested on whatever deployment server is going to be used.

Set up environment to test handling of multiple patients

Need to set up more machines (currently have access to 3 devices so maybe 1-2 more?) to test the system. (both by ethernet and by wireless)

Two way connection between unity and patient

Patient to unity connection is already established. Need a connection from Unity to patient application to detect inclines.

Establish single patient to clinician connection 2

Biodata + Bike Data
(need to check for memory leak!)

Create Settings for doctor side

Not sure what would be in the setting yet but if think of stuff should be in here... most likely some will come up during clinical trials.

Turning degree calculation

Current method to get the degress from clicks/second of rotary encoder might be wrong. Or the implementation of turning in Unity might not be correct.

Phone --> patient sockets are unstable

• Sometimes 2 out of 4 sockets connect (when call for creating the socket and waiting for connection are executed about the same time...) and then the other two won't for entire duration of the runtime
• sometimes out of nowhere, a socket at one port would disconnect when the other 3 sockets are transmitting fine
• often during transmission, some packets are lost (phone displays data change on UI but no UI change on C# side)

Unity Web Player template

The index.html file of the custom template has hard coded file path to the unity3d file. This needs to be changed to either:

1. uploaded file path (upload to server later?)
2. somehow get the path of the project and set the file path that way?

Detect loss of connection between patient(s) and clinician

If patient gets disconnected mid session, then should be able to reconnect. This should include detecting when the disconnect happens and gracefully closing the sockets...etc to prepare for reconnect.

Improve ECG display

Problem with old system:
- if graph was dragged by the mouse, it stopped plotting correctly. (scaling of axis were way off)
- speed of the plot was not influenced by the heart rate (faster heart rate = faster plotting speed)
- in effort to slow down the scroll process, it caused lag in displaying ECG data. It has to be done as accurate and live stream.
- buffering issue (possibly other issues) with receiving the data from sockets. Some data packets were lost.

create test project to isolate socket issues

related to #31 and #32 . creating an isolated test environment for debugging mentioned problems.

911 feature

Implement a feature for clinician to call 911 for the patient... this will require:

• an interface for the clinician to initiate the 911 call
• data sent to phone to retrieve GPS coordinates
• display the GPS coordinates on screen and have a call button to call 911
• be able to end conversation

Establish multiple patients to clinician connection 2

biodata + bike data

Fix the unity HTML file pathing

Change the file path to relative path (relative to project location).

Implement a improved notificationsystem

Current notification system for the doctor's side of the application is not very well designed. Think of a better way to notify the doctor if any of the patients' vitals are irregular.

Smooth out the turning process

Currently, every change of degree can be observed in unity. This makes the game a bit disorienting so only implement turns if the degree difference is larger than 5 degrees. (for example.. need to find the correct threshold.)
