Twente Intervention and Interaction Machine (TIIM) is a software created by the BMS Lab. Researchers, teachers, and students at the University of Twente can use the dashboard’s web application to create interventions, longitudinal studies, experience sampling method (ESM) or ecological momentary assessment (EMA) studies and questionnaires. Subsequently, through the TIIM’s mobile application, the researcher/teacher/student can gather data and/or distribute information/content to participants about different topics. It allows researchers to create sets of questionnaires and present them to participants based on a schedule or conditions. In addition, the studies can be adapted to individual participants due to the option to add item routing and questionnaire conditions. TIIM allows for interactive feedback, notifications and calculations, while giving you a better picture of your participants or patients by collecting wearable data when desired. The Twente Panel, a group of prospective participants, is created to aid the search for participants to join TIIM studies.
TIIM is ISO/NEN 7510/7512/7513 and GDPR compliant and it operates on ISO/IEC27001 certified infrastructure.
If you have any requests, questions or concerns regarding TIIM, please get in touch with our team by sending an email to dashboard-bms@utwente.nl
If you have questions or concerns regarding your study, please include your study ID (the four numbers in the URL when your study is open) in the email.

TIIM can be used for cohort studies, eCoaching, interventions, experience sampling, EMA/EMI, pilot testing, clinimetrics, wearable data, clinical trials and education & eLearning.
The IsolatieCoach research used TIIM as an interactive and personalised eCoach to support people during their process of isolation. Participants engaged in an interactive questionnaire where based on their answers, the app provided feedback.
Another example is the project: Using motivational interviewing combined with digital shoe-fitting to improve adherence to wearing orthopaedic shoes in people with diabetes at risk of foot ulceration: study protocol for a cluster-randomized controlled trial. TIIM was used to collect participants biometric data (steps and heart rate) and sleep, through their wearables. The full article is available on this link.
To reduce potential issues and challenges, keep the following points in mind before using TIIM for your research:
Longitudinal studies often require a large time investment from participants and complinace sometimes may decline over time. As such, we suggest that reserachers sufficiently inform the participants about the study in which they will participant and what will be expected of them, but also, instruct the participants about how to use TIIM itself. For that purpose, we have created the list below.
You can conduct ESM (Experience Sampling Method) studies using the ESM timing rules. You can choose whether participants receive questionnaires on fixed dates or based on their individual enrollment date.
You can schedule questionnaires in bulk for the full intervention, and you can also add reminders and notifications for participants. You can set how long a questionnaire remains open and decide whether it is sent at random moments (by specifying the minimum time between instances) or iteratively, at the start of each period.
In addition, it is possible to schedule single instances.
Here are few tips and tricks on how to do an E-diarisation study in TIIM.
Oftentimes when TIIM is used as a tool to facilitate learning, participants are asked to specify their learning goals or objectives. Using the dynamic text function can be used to call back to the goals or objectives specified by the participants.
Keep in mind that the module(s) that specify the goals and graphs should be part of the same intervention.
The item type graphs allows for visualisation of the progress of the participants.
You can use a different item type (for example, number slider) to ask participants to assess their knowledge or familiarity with a chosen goal. Then, using dynamic text option in the graph item type, you can create a graph showing their progress over time by dates. You can select the modules and the items from which the values in the graph will be shown.
You can enable the e-porfolio so that your participants are able to view and follow their results over time upon request.
You can invite participants to complete a questionnaire after each learning activity by using the on-demand module timing rule. This timing rule ensures that participants always have a questionnaire available to reflect on their learning activity and progress.
We advise you to carefully consider the starting moment of the study, choosing it to be close to a real life case or trigger that will start the process (such as lecture that is held on a specific day). Then, all of the participants can be automatically receive the intervention once it is available to them, by either scheduling the intervention to start at a specific date and time.
It is also possible to send reminders (both to all participants or individually) to ensure their retention.
Missing data can happen in the instances when participants have not answered specific modules. We advise you to consider the data as if it is liked, and not fixed (for example, in time). If linear processes are used, the missing points can be interpolated. It is also advisable to consider whether carefully examine whether you want within person or between person results, i.e. with high inconsistency of some individuals between person results analysis can still be done if the group is large enough.
For the participants it may be motivating and useful to use the graph item type, as it allows them to visualise their progress. You can also download the data per participant and individually send it to them to increase engagement or adherence.
Lastly, having enough data points may minimise the impact of the missing data and currently in TIIM all items in a module are mandatory to be answered.

After creating a study, researchers can enable health data gathering by navigating to the study detail page. At the bottom of this page, there is an option to enable health data collection. Once this option is enabled, the change must be saved. The researcher can then go to the modules page. After creating a module, several health sensor types will become available, including heart, steps, and sleep. The researcher can select which health data types they would like to collect. After selecting the data types, there is one shared time period setting that can be configured for all selected data types together. This can range from the last 30 minutes up to the last month, or a specific custom date range, for example from March 10 to March 20. The selected health data will be gathered when the participant finishes the module.
For iOS, the participant needs to connect their Apple Watch to their iPhone and allow the TIIM app to access health data through Apple HealthKit. Once permission is granted, the app can collect the selected health data based on the time period configured by the researcher. Heart data will return the participant’s beats per minute within the selected time period. Steps data will return the number of steps within each hour of the selected period. Sleep data will return the sleep states recorded during that period, such as In Bed, Awake, Asleep Core, Asleep Deep, and Asleep.
For Android, the participant needs to connect their smartwatch to their phone and allow Samsung Health to access the data and share it with other apps. After this is set up, the participant must also allow the TIIM app to connect with Samsung Health. The health data collection works similarly to iOS. Heart data returns the beats per minute within the selected time period and sleep data returns the recorded sleep states during that period. The main difference is steps data: on Android, steps will return the total amount of steps for that day, instead of the steps within the selected time period.
For UT researchers, we have a participant pool available upon request to supplement your data collection. However, to use the panel, you need to adhere to our best practices. Please keep in mind that the panel is a supporting resourse to your participant recruitment.
Researchers interested in using the Twente Panel must indicate their interest in their request registration. Each request will be evaluated to ensure it meets the necessary criteria before approval. To maintain the integrity and availability of the panel, studies can only be conducted using this resource once every few months.
To access the panel you must ensure that you have requested it via the BMS Lab request system when registering your study.
As such, you must show ethical approval, relevance, as well as methodological soundness. Your study will be checked by the panel’s administrator. If several requests are made for similar studies, it might be that you will be invited to collaborate.
Keep in mind that the panel can be accessed once every few months.
We recommend keeping your study short and focused to encourage high-quality responses.
Use a single default intervention so participants can begin immediately. Alternatively, coordinate with the panel administrator to ensure that participants receive the study questions as soon as they join.
You can include your informed consent form as a page under the subscription section of your study.
The panel is informed about the study with a notification and an email. Both use standard templates: only the study name, description, and unique voucher code will be customized based on your input.
Your study description must fit naturally within these templates, as the wording cannot be changed per study.
Template email:
Dear [Participant name],
We are excited to announce a new study, [study name], focused on [study decsription]. We invite you to participate and share your insights.
To join, please use the voucher code: [unique voucher code].
Template notification:
New study: [study name] is available for you to join. You can find the details in your email.
Some useful pointers when using the panel to maximise participation:
Be aware no reminders about your study are sent and responses may vary and depend on many factors, including above.
To send your study to the panel, the study and all communication in the app and all messages to participants must be fully set up.
This includes finalisation of questions, scheduling, notifications, reminders and emails. The study must be thoroughly tested as well. Once complete, you will need to contact the administrator who will then share it to the panel.
When contacting the administrator who will distribute the study to the panel, please indicate the study ID (4 numbers in the study URL) and indicate the desired time of the week when you would like the participants to receive the study.

Browse to https://dashboard.tech4people-apps.bms.utwente.nl, log in with your account. This will open the dashboard page. On the right click on ‘start a new study’, select the TIIM survey button and click on create new study.
It is not possible to re-open the study after the end date. In the study details you can change when the study begins and ends and under the subscription page you can decide when to open and end the subscription. These two data don’t have to overlap.
Participants can subscribe via the subscription URL. This can be found on the study home page and/or the subscription page.
When the participant wants to fill in their details, it is not possible to click on the grey word that details which information they have to fill in. They should either click on the right of the word or on the grey bar underneath it.
The email is sent by the BMS Lab email account, yet the participant will see it as if the e-mail had been sent by the researcher who created the study. This will allow the participant to reply to the researcher.
In the app under settings, the participant should see if the push notifications and email notifications have been checked.
Each participant is assigned an ID and the metrics and data export, you are able only to view them by the ID. However, in the participants tab, you are able to match the participant to their ID. The participants are pseudonymised, but not anonymised.
notifications and module scheduling are currently based on European time. This may cause participants in other time zones to receive content at unintended times.
Workaround:
At this time, there is no direct way to assign different time zones within a single intervention. As a workaround, you can:
This will result in two otherwise identical interventions running in parallel, each configured for a different time zone. These can be combined later if needed.
You can create an equation based on basic logical operators (+, -, /, (), * or 2^2) and so on.
Yes. Calculated variables can also be made with the numerical item types: Number Input, Number Slider, Number Dropdown and Number Choice.
