First Results of our Mobile Health Innovation Project

Written by Vicar on . Posted in Blog, Current Events, Future Events, Past Events

Last year we received an innovation grant from INNOLABS, for our project H2A2 – A Healthy Heart with Automated Assistance – to create an unobtrusive health monitoring tool. With an innovative technique, called remote photoplethysmography (remote PPG), heart rate can be detected from the face. This functionality is already available in FaceReader. Since this technique requires high quality recordings, we wanted to test whether it is also accurate when the camera of a mobile device was used. Together with our partner PLUX, a Portuguese company specialized in advanced biosignals monitoring platforms, and a Portuguese telecommunication company IT, we collected physiological ground truth data and video recordings from a tablet. This data can validate the heart rate assessment and emotion classification on a mobile device.

FaceReader 8 release! – More flexibility and extra possibilities

Written by Vicar on . Posted in Blog, Current Events

We are happy to announce the release of FaceReader 8, perhaps the most ambitious and elaborate release so far. It is now possible to measure expressions of children under the age of 2 (Baby FaceReader), to record audio and make infrared recordings, to measure consumption behavior, to analyze left and right action units separately, and to create your own expressions. For a more elaborative overview, see our partner’s page what’s new. In this blog post, we want to further go into the ‘create your own expression’ module.

In many futuristic movies, you see robots performing countless day-to-day tasks. Well… the future is here (almost)! For a project funded by COMMIT, we helped create a robot receptionist, named R3D3 (Rolling Receptionist Robot with Double Dutch Dialogue). The aim of this project was to create a combination of a virtual human and a robot capable of verbal and non-verbal interactions with humans. Together with University of Twente’s HMI and RAM, we succeeded in building a robot platform with the technical capacities to realize such interactions.

The R3D3 prototype can drive around, adjust its height, and carries a tablet with a virtual human face. The robot includes technology for speech recognition and speech production, and has FaceReader based computer vision techniques that can recognize gender, age and emotions. In addition, the virtual avatar on the tablet can interact with people. Here we report the results of three pilot studies, carried out to evaluate the performance of the robot and investigate how people reacted to it. Each pilot tested a different target population; shop visitors, police personnel, and children.

New Instruction Video for FaceReader Online

Written by Vicar on . Posted in Blog, Current Events, Media

With our web-based platform FaceReader Online you can gather facial expressions of people from all over the world. To make using this service even easier, we have created an instruction video that helps setting up a project. We also show how you can use Qualtrics, one of the leading survey tool providers, to embed the recorder within a questionnaire. In the video, you see the entire process: from setting up a project, incorporating the recorder in a questionnaire, to viewing the results, in less than 9 minutes.

With this approach, you can easily set up an online experiment. For example, you could measure responses to commercials, movie trailers, or instruction video’s. Before and after the video you can collect more data by adding questions about the video or the participant. It is an optimal approach for measuring subjective and objective opinions towards a product.

Are you a FaceReader Online user and want to start a project or are just interested in how this platform works, have a look at our tutorial video.

Which Politicians Have the Most Face-Time in Election Time?

Written by Vicar on . Posted in Blog, Current Events, Media

It is hard to miss: Dutch elections are on their way. In times of elections, it is crucial for politicians to get enough screen time. Which politician succeeds the most? VicarVision and Media Distillery worked together to answer this question!

With the newly developed tool LijstTracker, you can view the amount of minutes that each leader of a Party (in Dutch “lijsttrekker”) has been on television. The automatic facial recognition tools developed by VicarVision can recognise each politician in moving images. Whenever a politician appears on a television program, LijstTracker records the amount of time their face is visible.
