I think one major area of development will be in the use of wearables for healthcare and medical purposes. We can expect to see more advanced sensors and algorithms that can monitor vital signs and health metrics, allowing for more personalized healthcare and treatment plans.
One area of development will be in the integration of wearables with other technologies, such as augmented reality (AR) and virtual reality (VR). Wearables could serve as a way to interact with AR/VR environments, allowing for a more immersive and interactive experience.
I believe we will see more advancements in the field of smart fabrics, which could allow for wearable technology to be woven into clothing and textiles. This could lead to more seamless and discreet wearables, as well as new opportunities for collecting data and monitoring health metrics.
