    2. Introduction The ubiquitousness measurement framework can be used for measuring how ubiquitous the application or service scenario is The framework does not measure the quality, usability or any other quality factor of the application, i.e. high ubiquitousness measure does not imply high quality application

    3. Measurement dimensions Invisibility dimension, which has two components d=disturbance. The degree, how much a service disturbs the user in her actions. m=masking uneven conditioning. Is the user able to act normally, even if the service/application is not available or is not fully functional? Environment awareness dimension, which has two components: c=connectivity. The device where the ubiquitous service or application is located is connected to its environment. ca=context awareness. The service or application is able to monitor the context of its environment, itself, and its users.

    4. How to measure d (disturbance)? Proposed measures

    5. How to measure m (masking uneven conditioning) Proposed measures

    6. How to measure c (connectivity)? Proposed measures

    7. How to measure ca (context awareness)? Proposed measures

    8. Counting ubiquitousness level From the measures described before, we can count the level of Invisibility (I) using the formula and the level of Environmental awareness (EA) using the formula and as a result we get measure of ubiquitousness expressed by two numbers representing our two measurement dimensions

    9. Visual presentation The attached visual presentation can be used in placing the measurement result into ”space of ubiquitousness”
