| Abstract: | This research explores the area of affective computing by investigating the effect of relationships on social touch in an attention-seeking context. Social touch is a fundamental aspect of human interaction, being of importance in areas such as human-computer interaction, educational or workplace dynamics, and healthcare. A user study was conducted on 31 participants to gather touch gestures. Each participant needed to respond with a touch after reading a scenario in an attention-seeking context. Half of the scenarios were about familial interactions, and the other half were about stranger interactions. Leveraging machine learning techniques, models were built to classify between familial and stranger touches. Random Forest models with data segmentation based on a sliding window approach achieved the highest accuracies. Features were extracted on a global, channel, and sequence level, based on these segments. Nested cross-validation was used to evaluate the models. The best-performing RF model used a window size of 9 seconds and a step size of 4 seconds. It achieved an accuracy of 0.70. Results indicate a statistically significant difference in social touch between family members and strangers, although this difference is not exceptionally high. |
