Step one. When you send out logistics information to your workshop participants, please ask them to bring with them an item of technology that they love and one that they have abandoned. These should be portable. If not, ask them to take a photograph and bring that. At each table you need at least one person from the primary user group such as an older person, or person living with dementia. If someone from the target group comes with a caregiver and they wish to sit together that is fine. Leave a few spare chairs for people who turn up on the day.
