facial expression evaluation survey

Recommended Posts

Hi guys, this is a post requesting your kind participation to a survey that I have prepared in the study of human perception and classification of emotions (analysis and synthesis are the final goals). The survey consists in spending a few minutes labeling a few images. You (and your colleagues,friends and students) can participate in this survey comfortably installed on your chair by clicking to the following link: http://lts5www.epfl.ch/face/index.php That's what to do: 1. Choose a language. 2. The first time you have to create a new account (click on create a new user) and insert a few personal information. The socio-economics fields are important for us in order to segment the labeler population based on different background knowledge, age, occupation and education. The ethnic group is relevant for us to investigate the choice behavior of people when faced to images of individuals belonging to the same or to another ethnic group. IMPORTANT: the user can guarantee her own privacy choosing freely her own username and password. The data will be treated confidentially and only for scientific purposes. Anyway, most of the fields include a "None" option for those responders that don't want to answer. 3. Once logged in you can start a survey by specifying the place where you are (home, work or other) and choosing the number of images you want to annotate in the current survey. 4. By clicking on "Start the survey " you will start the labeling procedure for the chosen number of images. The following image shows the interface : For each image in the group you have to choose one of the available options and click on the right arrow in order to validate the current choice and pass to the next image . N.B.1 : The "I don't know" option should correspond to those situations where the expression is ambiguous. N.B.2 : if you find the survey too long you can stop whenever you want by logging off and restart from the first unlabeled image at your next login. 5. At the end of the survey push the "Validate Survey" button to validate the whole survey. 6. If you want and if you have time please make more surveys . Thanks in advance for your precious help
