ESM Wearable / ESM Board Admin
MetaWear Admin is a tool for using mbientlab MetaWear boards in experience sampling (ESM) research, which was developed at KL. The app is mainly tested and used with the wearable MetaMotion R. The idea is that researchers can use this tool to configure a device according to their needs (e.g. time/frequency of prompts, vibration, LED lights). The wearable can then be used independently and without having to be connected to a smartphone. All data is stored on the device itself and can be downloaded by reconnecting to the app at a later point in time.
ESM Wearable / T-Watch

In order to facilitate the conduction of Experience Sampling studies on a smartwatch form factor, we developed a firmware for the LilyGo T-Watch 2020 V2, a programmable smartwatch, here at the KL. This open-source software allows to easily implement studies employing self-reports on the T-Watch via simple configuration files. This allows researchers without programming skills to define the behavior of the device. The device can then notify participants and prompt them for inputs autonomously, with collected date being stored directly on the device.
Ease of Use
The device can be configured without programming skills. An open-source configuration application further simplifies this process.
The device works independent of other devices or an Internet connection. The configuration is read from a microSD card in the device, which also stores all collected data. This also increases data security, as they are only saved locally and not transferred over the Internet.
The firmware is open-source, meaning that the source code can be read and extended by anyone. This allows the firmware to grow over time, and enables researchers to independently add the features they need.
