In the CMS, the options for the LineChart appear as shown below.

The first option is to select a Question in the Study. The requirement for the LineChart is that the Responses from the Question have numeric values. If they do not, the Line Chart will show an empty graph.

The default Line Chart for a Question uses all Responses for the Question over the course of the entire Study.

Other options are as follows:

Show Axis Labels - This is an Enable / Disable slider. Data Labels will be visible along the Y-axis at fixed increments.

Y-Axis Increment Label - A typed-in element of units (such as “Drinks“ or “ppm“) will be added to the Y-axis increments if “Show Axis Labels“ is enabled. Does not show if “show Axis Labels“ is Disabled.

Show Threshold - sets a second line on the graph at a fixed Y-value. Displays the graph data value overlaid the Threshold value. If the Threshold is significantly higher than the highest point of Data, the graph is stretched vertically to show both the data and the Threshold.

Threshold Value - If “Show Threshold“ is Enabled, this is a number input for the Threshold Value to be rendered against the data values from the selected Question.

Show Cumulative Sum - The Linear Chart is able to show a linear sum of Question Data over multiple days, as opposed to showing a linear plot of data. Each Response value is summed with the previous data point value, starting with just the first point and ending with the Response value from the last Response.

Number of Days - Line Charts can designate a number of days to use instead of all Responses over the course of the Study. Inputting a positive number of Days, the displayed Cumulative Sum Line Chart will show the Response Data for the last number of allocated Days. Leaving the Number of Days blank will show all of the Responses over the course of the Study.

Typically, OutsightAndroidWear will automatically download to it. If it does not, a search through the watch’s Play Store as described above will work.

Troubleshooting

1. Ensure WEAR OS, Insight, and Outsight remain open and running in the background.

   1. If the app is open, Click the “Home” button (typically located at the bottom, center of the phone) to allow the app to run in the background. Example of a Recent window below:

      

   2. Note: If the app(s) are not displayed in the “Recent” window then the app(s) are closed; this prevents any background operations which hinder collecting sensor data.

2. Verify there is a connection between the smartwatch and phone.

   1. Open the WEAR OS app on the phone → under the watch name “connected” will appear if the phone and watch are paired.

      1. If WEAR OS signifies there is no connection, reestablish the connection by hitting reconnect

3. If there appears to be no connection, open Outsight and Insight on the phone.

   1. This can reestablish a connection between Outsight to Insight to allow sensor readings.

4. Restart the phone and watch if the above methods do not produce the expected results.

   1. Restarting Phone: hold down the power button (typically on the side of the phone) until Restart Phone appears → Click Restart Phone

   2. Restarting Watch: hold down the large middle dial on the side until Restart appears → Click Restart

5. Attempt to pair multiple phones and watches while thoroughly reading the instructions (starting from 1. Download Wear OS) to gain more experience; doing this can reduce quantity of errors when pairing the phone and watch.

Supported Devices:

• Fossil Smartwatch 5^th Generation

1. Create a new Event and set the Schedule Type to “Sensor Data“

   • Sensor Data can be scheduled to start at a specific time or any of the time offset (e.g., before sleep time)

2. Add a Setting ('+') to the “Sensor Data“ Event, also called “Sensor Data”

   1. Device: “Android Wear”

   2. Choose a Sensor Type

      1. Pedometer

      2. HeartRate

      3. Accelerometer

   3. Repeat Count and Sensor Read Frequency (milliseconds)

      • These values are tied with the Schedule Type/Time to schedule the start of sensor data collection and set how long the delay between readings should be, and how many times the readings should repeat (a repeat of 0 means there will be 1 reading, a repeat of 1 means 2 readings, …).

      • “Repeat Count“ is the number of times per day that this Sensor Event will trigger. The time increment between Sensor Events = T / 1440 (There are 1440 minutes in a day), where T is the value of the “Repeat Count“ field. T = 480 means that the Sensor Event triggers every 3 minutes for the entire 24 hour day.

      • Frequency is the length of time between Sensor Events, in milliseconds (0.001 sec). Repeat Count is the number of times that the Sensor Data event will trigger during each 24-hour cycle, based on the Select Time which is the start of the first Sensor Event. It is the responsibility of the Study designer to ensure that (Frequency * Repeat Count) total is less than or equal to 1440 minutes, which is 1 calendar day.

      • It is recommended to not have multiple sensors firing at the same time. If you need heart rate and pedometer readings, they should be set at least a minute apart as readings (particularly HR) may take time to complete and requests may be dropped if a service is busy with another reading.

      • There is a max of number of “events”, subdivided by day, that can be scheduled. This is a platform limitation, and may vary by vendor but any study scheduling more than 200 events per day should take caution. There is a convention that will leverage “repeating” sensor events and will allow more data to be collected. However, no assessments can be associated with a repeating sensor event (ie, follow ups).

      • If you wanted sensor readings every 10 minutes all day, you would set:

        1. Schedule Type = Specific Time

        2. Select Time = 12:01am

        3. Repeat Count = 143 ((60 mins * 24 hrs / 10) = 144 -1 for initial offset)

        4. Sensor Read Frequency = 600,000 (milliseconds)

3. Post-Sensor Reading Logic (cannot be used for “repeating events, see above)

a. If this formula evaluates to true, the Selected Assessments will trigger

• Events will only trigger if it is during the participant’s waking hours.

b. If left blank or if the formula evaluates to false, the event will passively collect sensor data.

c. This formula is not limited to sensor specific formulas. The usual question based formulas work here as well if you need to reference other data.

• Refer below for formula options.

Sensor Specific Formulas

• GetStepsPerMinute(n)

  • Gets the average steps per minute over a given duration

  • Ex: GetStepsPerMinute(30) < 8 would get the average steps per minute from the last 30 minutes and trigger an assessment if that value is less than 8. (less than ~8.33 steps per minute is sedentary)

Using Sensor Data in a Follow Up Event

• Additionally sensor readings can be generated through a “Follow Up” schedule type. For more information on how to setup Follow Up events, click here. Then start at the Step 2 of Creating a Sensor Event to configure the Sensor Data setting.

Creating BT iCO Question Type + Assigning to an Assessment

1. Create a Question with the Question Type iCO Bluetooth LE

   1. Fill out the associated fields for the question (Field Name, Required, and Description).

   2. Click Save once finished inputting information

2. Add the previously created iCO Bluetooth LE question to an existing assessment or create a new one.

3. (Optional) Facial Recognition

   1. (Question Tab) If the study has the “Facial Recognition setting enabled, and facial recognition verification is desired, create another question with the Question Type Face Verification

      1. Fill out the associated fields for the question (Field Name, Required, and Description).

   2. (Assessment Tab) If the study has the “Facial Recognition” setting enabled and facial recognition verification is desired for the assessment, add the Face Verification question type to the assessment immediately following the iCO Bluetooth LE question type added in Step 2.

How to use the Bluetooth (BT) iCO

When a participant reaches the iCO Bluetooth LE type question, the following will transpire:

The Insight app screen prompts the participant to connect the BT iCO device. When this screen is displayed, the participant should press and hold the power button on the iCO device until the LED ring at the base of the device flashes blue. Once the device is properly connected, the app screen shows Begin; the phone is ready for the participant to take the breath test.

Instruct the participant to press the Begin button → the screen will prompt them to hold their breath; a countdown is displayed to the participant. Once Exhale displays on the screen, advise the participant to exhale for the full length of the countdown.

Branching Logic

Branching logic is added under the Assessments tab; open the desired assessment then select Edit Formula for a question which will be conditionally presented to the participant.

Fill out the desired logic in the formula editor to determine whether the question will be presented.

For example, a basic check for results between 0 through 20 carbon monoxide concentration parts per million would look like this: [iCOBT] >= 0 and [iCOBT] < 500, where iCOBT is the “Field Name” of the iCO Bluetooth LE question.
