Online Experiments made easy

Building a state-of-the-art online experiment does not need to be difficult! With our editor you can visually create and run any experiment without needing to write a single line of code. The Labvanced experiment editor is built based on design principles from Experimental Psychology, which means you'll understand the system in a short time! All of your experiments structure is visible at a glance and you can play the current task to test how this looks for the participant.

The event system enables you to create powerful interactions and dynamics within your experiment. To define an event, you can listen for user input, variable changes, audio and video events, and more. Then, simply define the actions to determine what should happen: change stimuli, read or write variables, jump to a different part of the study, and many further options. Combining triggers and actions allows for infinite complexity with a simple to use interface.

Labvanced implements the current best-practices for recording reaction times in the most accurate way, But we don't stop there! In fact, we go beyond by using the intelligent caching of binary files, dynamic pre-rendering of all DOM content, frame onset correction based on requestAnimationFrame(), hardware performance tests, and passive recording of the JavaScript event-loop precision. Importantly, a 3rd party recently confirmed our superior methodology in this peer-reviewed publication.

Our calibration measures go above and beyond what other online platforms offer. With Labvanced, you can determine much more regarding the experimental parameters and the participant's online environment. Our calibration techniques include measurements of physical screen size (inch/mm), distance to screen (inch/mm), screen refresh rate (hz), CPU and CPU performance (calc/sec), whether the participant is wearing headphones (yes/no), and much more. All these parameters can be either passively recorded or used as participant inclusion criteria.

It is no overstatement to say that our eye-tracking technology (100% built by us) is by far the most accurate and capable webcam eye-tracking solution available on the market today. If you've only tried Webgazer or a Webgazer-based system so far, you will be surprised by the difference! Our solution finally offers researchers the powerful opportunity to go beyond standard behavioral measures for online experiments.

If you aim to record precise audio or video files, using the webcam or the microphone of participants in a GDPR compliant way, then you can easily achieve that with our system. You can even record the whole screen of the participant if that matches your experimental requirements. For audio recordings we offer both uncompressed (.wav) and size efficient (.mp3) encoding formats, and all binary files can be end-to-end (PGP) encrypted for maximal data security and data privacy.

Longitudinal studies offer deep insights into the progress and performance of subjects over time. Labvanced has several built-in mechanisms to re-identify subjects in an anonymous way, i.e. using a self generated token, or using external identifiers such as the PROLIFIC_PID, provided by our partners at Prolific. Importantly, our system then sends out several reminder emails at customizable time slots to improve return rates in longitudinal designs.

Multi-user studies, often also called multiplayer studies, are studies in which 2 or more people perform a task together. Prisoner's Dilemma or the Public Goods Game are two standard examples here, but with our system you can go way beyond that by transferring any kind of data between subjects and building truly interactive tests or even games. Our system takes care of synchronizing state/variables between people automatically, so you can just focus on building the content.

After you finish building the experiment, running the study online on our platform is only one out of several possibilities. For studies that need to run offline, we offer a lab/offline version. Also, using a local setup, you have the option of connecting Labvanced with external devices, such as EEGs, ECGs, GSRs, or eye-tracking hardware. A third option is to collect data online, but directly stream the data from the participant to your own server using our recording REST-API.

Labvanced serves customers from all over the world. Hence, there are multiple functions to translate and customize to language-specific requirements. We have automated translations for all of our 200+ system messages into 8 main languages. You can modify all of these translations to customize any message or even add a new language. Furthermore, you can also add translations for your own tasks so that people can choose their preferred language and get customized translations for all content provided.
