Ahn and Jenny, engineering students, are developing a wearable personal anomaly detector for elderly residents in aged care homes. The device, worn like a wristwatch, triggers an alarm at the nurses' station when it detects a rapid increase in the wearer's heart rate or when it comes within 1cm of the ground. Rapid heart rate fluctuations may indicate a critical event requiring immediate attention, while detecting falls is crucial, as elderly individuals often struggle to get up independently, leading to potentially severe consequences. Ahn and Jenny's detector distinguishes itself from existing solutions by monitoring both heart rate and falls. Therefore, they believe there is a market for their product but are uncertain and so are seeking your advice. What do you tell them? Is this an opportunity, and why do you hold that opinion
