While traditional interfaces in human-computer interaction mainly rely on vision and audio, haptics becomes more and more important. Haptics cannot only increase the user experience and make technology more immersive, it can also transmit information that is hard to interpret only through vision and audio, such as the softness of a surface or other material properties. In this workshop, we aim at discussing how we could interact with technology if haptics is strongly supported and which novel research areas could emerge.

Specifically, we analyzed data from a sample of 59 signers who were born deaf and investigated the impacts of face masks on non-linguistic characteristics of the face.

This experiment was a repeat of a previous study conducted on hearing participants, and a post hoc comparison was performed to assess rating differences between signers and hearing people. From this comparison, signers exhibited a larger tendency to rate facial expressions more intensely than hearing people.

abstract = {Inertial sensors integrated into smartphones provide a unique opportunity for implicitly identifying users through their gait. However, researchers identified different external factors influencing the user's gait and consequently impact gait-based user identification algorithms. While these previous studies provide important insights, a holistic comparison of external factors influencing identification algorithms is still missing. In this explorative work, we conducted a focus group with participants from biometrics research to collect and classify these factors. Next, we recorded the gait of 12 participants walking regularly and being influenced by eleven different external factors (e.g., shoes and floor types) in two separate sessions. We used a Deep Learning (DL) identification algorithm for analysis and validated the analysis results using within- and between- sessions data. We propose a categorization of gait covariates based on users' control levels. Floor types have the most significant impact on recognition accuracy. Finally, between-session analysis shows less accurate yet more robust results than within-session validation and testing.},
