Connectedness – Social Enabler

Connectedness in human-robot interaction refers to how robots affect human relationships and social life. In particular, a key concern is whether robots replace human contact or instead help maintain and strengthen it. In everyday settings, especially in elder care and assistive technologies, this distinction becomes important: the value is not just in what the robot does for an individual, but in how it shapes relationships with others.

Within this framing, the idea of a social enabler describes robots that actively support human-to-human interaction. Rather than acting as substitutes for social life, these systems can facilitate communication, reduce barriers to contact, or create opportunities for shared activities. This can include helping users stay in touch with family and friends, supporting participation in group interactions, or simply acting as a conversational bridge in situations where initiating contact might otherwise be difficult. The underlying intention is to preserve and extend human relationships, not replace them.

Empirical and conceptual work in HRI repeatedly highlights this enabling role. Robots are described as supporting regular contact with loved ones and providing controlled access to new social encounters, particularly in contexts involving aging and care. In some cases, users report turning to digital assistants during moments of emotional distress, even when the response redirects them toward human support networks rather than continuing the interaction itself. This reflects a design stance where the robot acknowledges its own limits and reinforces external social ties.

Beyond one-on-one interactions, robots can also increase social engagement by acting as intermediaries in care networks, either through direct interaction or by connecting users with other people involved in their support system. Similar observations appear in work on long-term care, where robots are seen as tools for increasing virtual visits and reducing social isolation by strengthening family contact over distance. Even therapeutic or companion robots can play a role in shared experiences; for example, interacting with a robot pet has been shown to support communication between family members in care contexts. Importantly, this role is not limited to emotional comfort or companionship in isolation. Studies also emphasize that socially assistive robots can free up human caregivers' time, indirectly enabling more meaningful human-to-human care. In a similar way, robot pets and companion systems have been described as social facilitators that increase interaction not only between user and robot, but also among people around the user. Across these perspectives, the central idea remains consistent: robots are most valuable socially when they help maintain, scaffold, or amplify human relationships rather than replacing them.
