This study will be hospital-based, including paediatric emergency department (PED), inpatient wards and outpatient departments).~The participants will have their vital signs (such as heart rate, respiratory rate, oxygen saturation, blood pressure and temperature) measured using standard-of-care methods. Concurrent with this, videos of the participants' face/torso, and audio of the sounds made by the participants (cry, wheeze, cough) will be recorded. These data will later be used to train the Lifelight® Junior algorithms so that the technology can help in detection of illness and deterioration in children.~Primary Objective Collect the data needed to develop Lifelight® Junior so that it can measure the heart rate, respiratory rate and oxygen saturation of children.~Secondary Objective~Assess the feasibility of developing other (direct or indirect) measurement functions in Lifelight® Junior, including temperature, blood pressure, heart rate variability and audio analysis (cry, wheeze, cough).~Evaluate the impact of subject-specific variables on the vital sign measurements e.g., medication, cosmetics, facial/body hair and skin tone.~Obtain data to understand patient and parent/guardian/carer vital sign measurement habits and preferences~Assess the usability of Lifelight® Junior for measuring vital signs in children~To ensure the study collects data that can train Lifelight® Junior in an efficient way, the recruitment should be divided as follows:~At least 12% of study participants should fall into each of the following age bands:~Age 0-1~Age 1-2~Age 2-5~Age 5-11~Age 11-14~Age 14-18~At least 40% of the study participants shall be male and at least 40% shall be female.~At least 40% of the study participants shall be each of the following:~Febrile (≥ 38°C) measured how?~Afebrile~Ill (as judged by the clinical staff), of whom at most 50% shall have an acute respiratory illness e.g., bronchiolitis, asthma, viral induced wheeze, pneumonia, croup, etc.~Well, including children with a minor injury~Ideally, 15% of participants should have a Fitzpatrick skin tone of 4, 5 or 6 First reference to this - need to bring it in earlier and to reference it. However, this is not a hard target as achieving this figure is dependent on the demographic diversity of the study region.
