Overview of the results of the interviews categorized into themes, categories and a summary

Themes	Categories	Summary
Camera recording	Control over the camera	Patients indicate that they would like to control when the camera is turned on and off (81%). It would not be a problem if the camera is visible (69%) and patients would consent for continuous measurements of 2 weeks up to 3 months (100%).
	Visibility of the camera
	Recording duration
Privacy protection	Patient’s behaviour	Patient’s behaviour would probably be affected by awareness of the camera in the beginning (62%), but this will quickly reduce to normal. It is important that not only patients consent to being filmed, but also partners and depending on the location other people visiting the house. The living room was acceptable for all patients (100%).
	Partner’s consent
	Camera location
Perceived motivation	Contribution in science	The motivation of patients to participate in these projects relate to contributing to science and thereby helping future patients (100%). A potential personal benefit, when these video techniques would be used to give feedback on functioning to their treating physician, would also be a strong motivation.
	Helping other patients
	Personal benefits
