# Scope of Application
LightMove 4 is a scientific research instrument that captures the ambient light, physical activity and other secondary parameters derivable from these measurement signals. LightMove 4 is designed and tailored for the use in research applications.
The Ambient Light and Physical Activity Sensor LightMove 4 is not a medical device!
The sensor measures the physical activity of a person based on the acquisition of acceleration in three dimensions and atmospheric air pressure. Moreover the sensor also records the rotation rate and the ambient temperature. The ambient light is detected via a color light sensor. This sensor allows the measurement of Lux, the brightness measurement over a wide range (darkness to sunlight), color temperature measurement and light source type detection (enabled by an integrated additional IR channel).
The sensor configuration occurs via a USB connection to a Windows PC using the Sensor Manager software included in this package.
LightMove 4 allows the measurement of the following parameters:
Light Intensity in 5 channels
Acceleration in three dimensions
Angular Rate
Atmospheric Air Pressure
Temperature
Marker
State of Charge
In conjunction with movisens DataAnalyzer the offline calculation and analysis of the following parameters is possible. In addition to these parameters, reports can be generated.
Light Illuminance (lux)
Color temperature (K)
Movement Acceleration and Step Count
Activity Classes and Body Position
Energy Expenditure
Reports
In addition to the offline calculation, LightMove 4 offers the possibility of live analysis of physical activity and in conjunction with movisensXS, the software platform for experience sampling, and the Sensor Trigger the realization of interactive ambulatory assessment strategies. In live mode, the following parameters can be measured, calculated and transmitted via a Bluetooth Smart interface:
Movement Acceleration
Step Count
These values are transmitted with 1 value per minute. Additional live parameters will be available soon.
Movement Acceleration is calculated in segments of 30 s. The transmitted value is the mean value of two segments.
Parameters that are marked with “(Bluetooth)” are only transmitted over Bluetooth interface, they are not stored on the sensor.

# Handling
This chapter describes how to prepare a measurement and how to attach the sensor to a test person. Furthermore you get information on how to save, delete and analyze data from the sensor.
A typical usage scenario for the assessment of data and offline analysis is shown in the following diagram. The relevant software for each step is indicated on the left side of the diagram.
The different steps are described in further detail in the chapters indicated on the right of the diagram.
If you want to use the sensor in combination with the experience sampling platform movisensXS, the different steps to use the sensor are shown in the following figure. Unlike the offline measurement, the measurement is initiated on your mobile device.
The right side of the diagram illustrates the process to prepare and run a study on movisensXS.
To retrieve the data from the LightMove 4, you have to read out the sensor after the measurement. The results of movisensXS only contain the sensor information that causes a trigger.
# Charging the Sensor
Step 1: Connect the cradle with the USB cable to a USB port (USB port of your computer or another port that conforms to USB standard like USB hub or USB charger). Attach the sensor with the help of the push buttons at the cradle. Please make sure that the 4 contacts are connected (marked red in the picture). To charge multiple sensors at the same time, we suggest using a USB hub (see 4.2).
After connecting the sensor to a USB port, the charging process starts immediately. During charging, the status LED is blinking blue. If the battery is fully charged, the LED is blinking green. The charging process of the sensor can take up to two hours, depending on the battery status of your sensor.
If the sensor is fully charged, the battery run time during recording is 7 days.
Step 2: To extend the measurement duration you can recharge the sensor during a measurement.
If recharging while taking a measurement be sure NOT to plug it into your PC as that will stop the measurement. Instead use a USB charger.
When recharging the sensor please ensure that the battery is fully charged (until the sensor is blinking yellow).
To be sure that the sensor is not running out of battery, you must advise the test persons to recharge the sensor every day until it is blinking yellow. The time for daily recharging the sensor is about 15 minutes.
If you recharge the sensor regularly you can make a measurement up to the maximum recording capacity of the sensor of about 4 weeks.
If the sensor runs out of battery lifetime during a long measurement, the recording of data will be stopped. The measurement won’t be continued even if you connect it to a charger.
If the sensor is discharged completely (e.g. after a long period where it was not used), it can take up to several minutes until the sensor reacts and can be identified by the computer.
You can control the battery status before the measurement with the sensor manager, see the following section.
# Preparing a Measurement
Before conducting a measurement please make sure you installed the software as described before.
Step 1: Start the SensorManager by selecting
Windows Startmenu => movisens SensorManager => SensorManager
SensorManager is now searching for available sensors.
Step 2: Connect the LightMove 4 to your PC using the cradle.
- The software will automatically detect the device and open the following window:
This application shows information about the sensor, parameters that are measured and the last measurement.
Before you start a measurement please check the charging status of the battery. The maximum measurement duration can only be reached when the battery is fully charged.
- When connecting for the first time allow up to 30 seconds for the device to be detected, as it must first install the necessary driver.
# Starting a Measurement
To start a measurement, please perform the following steps:
Step 1: In the SensorManager software click on the “Start Recording” button in the lower left of the window.
You can see the following window:
If the battery level of the sensor is less the 10 % when clicking on the „Start Recording“ button, the following message appears.
Please connect the sensor to an USB charger!
Step 2: Configure the measurement:
Measurement duration: The maximum measurement duration of the LightMove 4 is about 7 days without recharging the sensor. (see 7)
Start time: You can start the measurement immediately or delayed at a specific time. If you want to start your measurement delayed please specify date and time. The given time should not be more than 2 days from now as the maximum measurement duration can be influenced.
You have the possibility to enable the Bluetooth interface of the sensor during the measurement by clicking the checkbox.
You can enter the personal information of the proband. This information can also be entered when storing the data after the measurement. For some of the parameters that can be calculated live on the sensor during the measurement, the additional information about the person and the sensor location is mandatory.
The age of the person can be calculated from birthdate. To do this, you have to enter the birthdate and press the “<” button.
If the sensor is used for the second time with the same proband and the personal data was stored before, you can load this data by clicking “Load proband info from Sensor”
Step 3: Start the measurement by clicking the “Start” button.
You will see the following window:
Step 4: Please follow the instructions and remove the sensor from the Cradle.
Step 5: Check if the LED is flashing red
The status LED will flash red once per second as soon as the measurement has started and data will be recorded. If a delayed start was configured the LED flashes red every two seconds until the measurement starts.
At the end of the measurement the LED stops flashing.
If you reconnect the sensor after starting a measurement again with a PC, the following message is shown:
Please select if you want to stop the measurement, e.g. to read out the data, or if you want to continue measuring.
If you connect the sensor to a USB charger, the measurement won’t be stopped. That means you can extend the measurement duration by intermediately charging the sensor during a measurement (see 7.1).
If the battery level of the sensor is getting lower than 10 %, the measurement will be paused. The LED stops flashing. You can connect the sensor to a USB charger and recharge the battery. If you disconnect the sensor from charger after battery level is higher than 30%, the measurement will be restarted.
# Attaching the Sensor to the Test Person
Use the wrist band to attach the sensor to the non-dominant hand of the test person. At this position, only simple parameters like Movement Acceleration can be measured.
Depending on the position of the sensor, different parameters can be analyzed after the measurement. Please refer to the manual of the DataAnalyzer for more details which parameter can be calculated at which sensor position.
The following figure lists the possible sensor locations.
# Setting a Marker
Markers can be used in measurements with the sensors to mark specific events. Markers can be set either during or after the measurement. They can be used to annotate the measurement data to better understand what happened during the measurement. They can also be used to mark certain areas that require special attention when analysing the data.
# How to work with markers
1st possibility: marker can be set during measurement. Therfore the user has to tap two times on the front side of the sensor. The sensor vibrates to confirm the successful setting of a marker.
2nd possibility: marker can be set with our Marker Tool request information.
3rd possibillity: marker can be set after measurement within the UnisensViewer (opens new window).
Open the measurement with the UnisensViewer tool. If markers already exist, right-click in the marker window and select 'Set marker'.
If there are no markers, a marker can be set in any window. Note that the sampling frequency (and therefore the precision of the time definition) depends on the signal in which the marker is set.
Recommendation: Set the markers in the signal with the highest sample rate.
A new file will then be created for the markers and a name must be given to it.
Recommendation: The file name should be self-explanatory, e.g. "marker".
Edit marker: Open the file marker.csv with a text editor.
A marker (line) consists of a marker type (e.g. M1) and a marker comment (e.g. Start), separated by a semicolon:
⋅⋅*M1;Start;
The name for the marker type should be kept as short as possible.
In the UnisensViewer only the marker type is displayed over time, in the sidebar also the marker comment of the marker to the left of the mouse pointer.
Analyse marker:The measurement with markers can be evaluated with the DataAnalyzer.
The markers are displayed in the Results.xlsx file.
# Stopping a Measurement
The measurement will automatically be stopped, if the configured measurement duration has passed.
A running measurement will also be stopped when:
The sensor is connect to a PC
The end of the battery run time has been reached
If the battery is low, this is indicated by fast blue flashing (three times per second). The sensor will then turn off soon.
# Storing Measurement Data
The measurement data of the sensor is stored as raw data (e.g. the acceleration data as it is measured). The data is not processed or aggregated neither in the sensor nor in the SensorManager software. That allows you to have a sustainable database with all the raw data of your study that can be used with future studies and with future algorithms.
To store recorded measurement data on the PC do the following steps:
Step 1: Start the SensorManager by selecting
Windows Start menu => movisens SensorManager => SensorManager
Step 2: Connect LightMove 4 to the PC using the cradle.
- After the SensorManager has detected the connected sensor, the following windows will be shown:
Step 3: Click on „Save Data“.
- You will see the following window:
Step 4: Please type in the following information:
Select the base folder, where your measurements should be stored. To do this, click the button after the text field.
Type in the ID of the measurement. If you want to use date and time in the ID click the “Timestamp” button.
If the measurement data shall be further processed with the movisens DataAnalyzer the additional information about the person and the sensor location is mandatory. If you stored the information about the person at the beginning of the measurement, this data will be shown here.
Step 5: Finally click on „Save data“
The measurement data will be stored either in the unisens format or as .csv file. Unisens is an open data format for multi sensor data. You can find further information about unisens here: www.unisens.org (opens new window)
- If you store the measurement data in .csv format, you can’t analyze the data with the movisens DataAnalyzer.
A unisens data set consists of a meta file (unisens.xml) and different data files for each measurement signal. If you store data in unisens format, the following files will be generated:
The software confirms the end of data storing process. The following window is shown:
You can select if you want to delete the data on sensor. The data on the sensor has to be deleted before you start a new measurement. You can do this now or directly when starting the next measurement.
- After this, you can select how to continue.
You can now directly show the stored data. We recommend that you open the data within the UnisensViewer to check for completeness.
This is the default option if you hit enter at this stage.The measurement will be opened in the UnisensViewer. You can use this program to crop and edit the signal, and to make sure that the measurement signal appears clear and intact. More information about the ECG signal is in chapter 8.5
If you have installed the movisens DataAnalyzer you can directly start data analysis and generate reports by clicking on “Analyze data”. You can find more information in the DataAnalyzer User Manual.
# Multipart Measurement
If the measurement was paused because of a low battery level, and continued after recharging the battery, the measurement is stored in multiple parts.
In this case, the selection how to continue looks like in the following window.
If you want to check the measurement data, you have to go to the folder and open the different parts of the measurement with UnisensViewer.
A Multipart measurement can be analyzed with DataAnalyzer by using the batch mode (see DataAnalyzer User Manual). The results of the multiple parts of the measurement can be merged with DataMerger (see DataMerger User Manual)
# Viewing Measurement Data
To view recorded measurements click on “Show data” directly after storing the data.
To view previously stored measurements use Windows Explorer to navigate to your measurements folder and then open the folder with the desired ID. Then double click on the “unisens.xml” file. The measurement will then be shown in the UnisensViewer:
A first preprocessing of the data can be done with UnisensViewer. You can crop your signal to the desired time, set markers and annotate artefacts. Details can be found in the online help of UnisensViewer.
You directly start the analysis of the data with DataAnalyzer by clicking the “Analyze Data” button.
# Analyzing Data
Option:
To analyze the datamovisens offers the modular analyzing software DataAnalyzer. This product is a scientific software application for the analysis of physiologic measurement data. The software is optimized for, but not limited to use with sensor systems from movisens
With the help of the DataAnalyzer, you can calculate secondary parameters from your physiologic measurement data, create summaries and reports. DataAnalyzer can batch-process complete measurement data bases.
After selecting a measurement, the DataAnalyzer displays all the possible analysis outputs (secondary parameter and reports). The list of analysis outputs depends on your licensed modules and the data contained in your measurement. You can now select the desired analysis output(s). If you want to select more than one analysis output keep the Ctrl-key pressed while selecting.
The results of the analysis are stored as a unisens data set. A unisens data set consists of a meta file (unisens.xml) and different data files for each measurement signal and secondary parameter. Secondary parameters are stored as .csv file within the unisens data set and can be processed e.g. with Microsoft Excel or SPSS
