IOT - Applications
• E-health – Eg. home care
• Well being – Eg. Tools for reflexion of your own health
• Performance och learning– Eg. Violin player, Heart rate monitors
Þ Same technical infrastructure but different market and regulations

Challenges• Building robust applications is not easy
– Sensors– ”Smartphones”-apps
• battery consumption
– Smart feedback to users– Cloud solutions (storage, users, payment,..)– Connection to Social networks
• Scalable support– Light weight infrastructure (from 2 users to many)
