Consuming media together is enjoyable and lets people connect with one another. However, the control of a TV, for instance, is still restricted to one user. this limits individual participation in group decision-making, particularly in the home context which can cause frustration and impact social interaction negatively. In this paper, we explore how we can support users in the living room to collaboratively interact withthe TV in order to enhance social interaction and support the selection of a movie everyone is up for watching. therefore, we investigate three collaborative approaches to movie selection: Consensual, Hierarchical, and Autocratic. We empirically validated the approaches' effect on perceived co-experience, social connectedness, and team performance as indicators for social interaction. therefore, we conducted a mixed-subject experiment (N=30, 10 groups) inside a living room in groups of three choosing a movie together. Results show that the collaborative approach to movie selection has an influence on collaboration and social interaction. Promoting consensual decision-making or enabling users to provide movie recommendations under the hierarchical approach empowers individuals, supports involvement, and is perceived as fair while also enabling a higher chance of picking a movie everyone enjoys watching. Letting only one user interact withthe TV, stimulates communication, yet, it enhances the chance of excluding group members. Founded on these insights, we discuss suggestions for the future design of collaborative, interactive media systems toward co-experience and social connectedness.

Withthe proliferation of medical Internet of things (IoT) devices that collects sensitive healthcare data, access control is more crucial than ever to ensure medical IoT data from unauthorized use. the security and privacy of medical records must be addressed rigorously. the security protocols and distributed system architecture are designed for effectively implementing the access control mechanisms to prevent privacy leakage and insecure data sharing. Blockchain is a promising candidate for strengthening the security and privacy needs of IoT medical systems. this paper proposes a blockchain-based access control mechanism for IoT medical data. Medical IoT data can be encrypted and stored off-chain in a distributed file storage system. Data access transactions only record the address of the data ciphertext and the encryption-key ciphertext into the blocks, which can significantly improve the scalability of the blockchain and strengthen privacy protection of medical data. the immutable nature of blockchain ensures the integrity and authenticity of medical data. Our BAC-IOMT scheme embeds the access policies into smart contracts to execute data access control mechanism. Finally, this scheme is proven to be secure and its performance efficiency, data volume and delay are analyzed in detail, the experimental results show that it is efficient and feasible.
