Motivation Museums have begun to use more technology in interactive exhibits. Interactions are still general for all users.

Research Problem Change the content of museum exhibits to match the age of their audience.

Possible Solutions Physical user input… User must understand and use the interface. Audio user input… Language dependent, must isolate user’s answer. Gait analysis… Requires video input and human tracking from multiple angles.

Project Goal Classify humans by age group using facial images. Child Young AdultSenior

Approach Test Image Training Images Training Dataset Test Dataset ClassifierAge Group Feature Extraction Machine Learning Algorithm

Data Collection Use video or stills to provide images of the user. Extract usable data from the images. Output data to classification program.

Principal Component Analysis PCA reduces the complexity of data by reducing the number of features in the dataset. The result is a series of vectors for each image.

Evaluation Training and test images from the Center for Vital Longevity Face Database. Evaluation of the approach is carried out using 10-fold cross validation. Kennedy, K. M., Hope, K., & Raz, N. (2009). Lifespan Adult Faces: Norms for Age, Familiarity, Memorability, Mood, and Picture Quality. Experimental Aging Research, 35(2),
