This chapter argues that computer based messages delivered in the home (such as the status of your house or reminders to take your medication) should be available in multiple sensory modalities (visual, auditory, tactile and olfactory) in order to increase the usability and acceptability of home care technologies and make them accessible to a wider range of users. We present an overview of ‘multimodal interaction’ and how it can be enable the delivery of information to the user in a way that is more appropriate to the user's needs, the devices available in the home, and the physical and social environment that the person is in when they receive a message. We conclude with some general guidelines and lessons on how to design personalisable multimodal assisted and independent living technologies for the home.
