You will be visited by a member of the research team in your home. You will be asked to wear a special pair of glasses that contain sensors that produce a video recording of where you are looking as you move around. Looking in the right places at the right time is important for walking safety and the information we get from the glasses will help us understand if there are distractions in the environment that compromise safety or if inadequate lighting is affecting your ability to see important features such as stair edges or trip hazards. The glasses are light-weight (less than 50g) and can be fitted with prescription lenses to match your own glasses if you usually wear them. The glasses plug into a smartphone that can be worn in a pocket or on an armband. You will also be asked to wear a lightweight wristband that measures your heart rate and skin characteristics to give an indication of stress/anxiety levels.

​

You will be asked to wear the glasses and wristband during a single 1.5-hour session while you carry out normal daily living routines and activities (e.g. walking through a communal area, preparing food, negotiating stairs etc.) The researcher will give you instructions on various activities to carry out but will not be following you or supervising for the whole session. At the end of the session you will be asked to return the equipment and you will be asked some questions about the activities you carried out to give you a further opportunity to ask any questions about the study or raise any issues.
