A new phase of research examines 'intent to wander' amongst people with dementia. The most suitable technology
                            for a prompting or dissuading devices is an infrared or ultrasonic sensor. In the Smart House, a bedside light
                            comes on when a person with dementia rises from their bed during the night. A text message is sent to the carer
                            and a prompt will be given to the individual to remind them to return to bed. The study considers the psychological
                            nature of prompting and will examine the most effective method of communication with the person with dementia
                            and the best timing for this prompt. Examples include a blast of air, a clock face displaying the time to prevent
                            nightime wandering, or a familiar voice recording. The second new phase of research involves the installation of
                            alarms to
