Our society is changing. The role which information and communication technologies (ICT) play in our society is growing rapidly and meanwhile the world’s population is ageing. ICT has enabled social network sites (SNS), which are often targeted towards younger people and is therefore less suitable for seniors who find themselves displaced again and again. Through a design research oriented study, we explored the theories of non-traditional computing to find alternative ways of using technology to better meet the needs of seniors. We have found bridging technologies to be a promising domain that could help address the life-changing consequences of population ageing. We have identified four design principles to support the design of bridging technologies, geared towards enabling seniors to interact with social network sites. These principles constitute our final contribution.
