Context-awareness indicates that a computer system is linked with changes in the real world. Context information can be used for numerous different purposes, but the real break through is still pending. Context information is useful only when it is not static, and hence in desktop computers there is very limited need for context awareness. In mobile phones situation is different. MUPE is an Open Source application platform for creating mobile multi-user context-aware services. It is based on client-server architecture and both server and client are capable context providers. A typical client context would be GPS location or Bluetooth ID. Typical server context would be information like weather or stock market. This paper introduces context-aware services made by professional and non-professional and compares those against each other to point out that context-awareness under MUPE is easily and rapidly utilizable even for non-professionals developers.
