DataAnalyzer

Once again we expand the capabilities of the DataAnalyzer, incorporating a new Sleep Report. The Sleep Report provides a quick visual overview of the sleep activity of your participants.
It's the perfect tool to quickly assess their sleep behaviour, and also a fantastic reward for your participants to help encourage their study compliance.

The winner of the student project of the year competition 2021 from movisens has been determined!

During the last year movisens supervised more than 15 exciting student projects and received their application for the competition. Since all projects were groundbreaking and innovative, it was not easy for us to choose the winner. Nevertheless, there can only be one winner, so …
… Congratulations Wiebke Blum & Paulina Fried from Aalborg University for winning the Student Project of the Year Award 2021!

Here is a quick description of the student project they dealt with during the last year:

How does it feel to walk in Berlin?
Designing an Urban Sensing Lab to explore walking emotions through EDA sensing
Developments in technologies such as biosensors, GPS and ICT make real-time assessments in a participatory urban process increasingly efficient and accessible. With global, but also local ambitions to design sustainable, liveable, and barrier-free urban spaces, people and their desires are increasingly moving into the focus of science and practice. Urban walking and pedestrianfriendly cities have grown immensely in importance in recent years, reflecting not only necessary adaptations to climate change and the SDGs, but also the desires of modern citizens. For participatory and people-focused urban planning processes, the concept of Emotional City Mapping can help by providing an innovative approach to integrate people’s emotions. With both subjectively and objectively measurable, physiological data, more holistic analyses and images of an environment can be generated, leading to better informed decisions. The aim of this thesis is therefore to explore whether and how it is possible to collect such objective, emotional data and, furthermore, how it can be combined with other data sets and ultimately visualised in emotional maps. In an Urban Sensing Lab environment, geo-referenced emotional data is collected from participants via EDA sensors as they walk through a Berlin neighbourhood. Both individual points and clusters of stress can be detected, which can provide further information about the emotional experience. Finally, the designed emotional maps can be used for participatory planning and decision-making processes and support local transformation projects towards a more sustainable, inclusive, and pedestrian-friendly city of Berlin. read the whole paper...

SedentaryMood-Study (Part V)

The following article is part of a series about the "SedentaryMood-Study".

Measurement times of the real-time study

In the last article, the sedentary sedimentary triggered e diaries and the randomly selected queries were described. In the next step, the study plan used for the SedentaryMood-Study is explained. Here, the frequency of the mood polls during the course of a day plays an important role.

The exact number of queries depends on the individual participant's level of activity and thus, as in this study, up to 12 queries per day can be expected. More mood queries per day over a longer period of time are not to be recommended in order not to overstrain the associated willingness of the test persons to participate and thus not to endanger the data quality.

On the basis of study results, about three to five days - of which at least one weekend day - are necessary for a representative recording of sedentary behaviour. In view of this, the survey period, the SedentaryMood Study, lasted five days (three working days and two weekend days).

The sample was recruited from the University of Newcastle (UoN, Australia) and the Karlsruhe Institute of Technology (KIT, Germany). Participation in the study was linked to the following inclusion criteria: official co-worker of the institution, no illness or injury, and the work was performed predominantly in a sedentary body position.

SedentaryMood Study (Part IIII)

The following article is part of a series about the "SedentaryMood-Study".

Sedentary Triggered e-Diaries

The methodical core of the "SedentaryMood-Study" is the use of Sedentary Triggered e-Diaries. As far as is known, no comparable technical solution has been implemented in any study to date.

In this case, the application aims to capture psychological parameters precisely during long sitting phases. Sedentary behaviour is recorded, analysed in real time and mood queries are generated when defined thresholds are reached. The threshold for long sedentary behaviour is 30 minutes. The communication between smartphone (e-Diary) and accelerometer takes place via a Bluetooth low energy (BLE) connection.
In the practical implementation of this study, Sedentary Triggerd e-Diaries as well as random time points in the daily routine were selected. In addition, at the end of a study day, the test persons were encouraged to subjectively indicate the entire duration of the completed day.

The figure shows a triggered query with movisensXS.

Sedentary Mood Study (Part III)

The following article is part of a series on the "SedentaryMood Study".

Preparations to determine the body position

As part of the "SedentaryMood Study," the Move 3 activity sensor was used for the first time to capture sedentary behavior as a primary target variable. Thus, some preparatory work was necessary in the run-up to the study. These were aimed primarily at the detection of the body position.

In order to determine the most suitable carrying position for the activity sensor and thus to differentiate between sitting and upright body positions, two video studies were carried out. On the one hand in everyday life with different activities and body positions and on the other hand during office work in everyday working life.

The evaluations of both measurements show that a carrying position of the activity sensor Move 3 between the sagittal axis and the longitudinal axis, an upright body position is assumed. If the sensor is in a position that exceeds the angular range of < 20° between the sagittal axis and the longitudinal axis, an upright body position is assumed. If the sensor is in a position that exceeds the angular range of > to the sagittal axis, then a seated / lying body position is specified.

As the measured data of the activity sensor Move 3 analyzed, coupled with the e-Diary movisensXS and triggered with the SensorTrigger you will learn in the next article ...
