Outline1. Mobile gadgets functionality has until now been

identified as human-human communication, games and accessories.

2. Psychologists and Rhetorics identifies a new emerging functionality called cognitive support tool. Furthermore a new research field has emerged “Persuasive Technology” in which technology should be designed to influence the users behavior. Persuasive Cognitive support tool helps the user to manage their life and improves their social skills.

3. Signalprocessing appears to play a crucial role in the core functionality of Cognitive Support tools.

Disclaimer” Signal processing is an area of

electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time, to perform useful operations on those signals. Signals of interest can include sound, images, time-varying measurement values and sensor data, for example biological data such as electrocardiograms, control system signals, telecommunication transmission signals such as radio signals, and many others.”

B. Mobile loyalty“Mobile applications that are perceived to serve

the needs and wishes of the owner firs, rather than those of an outside party, will have greater persuasive powers.”

… As I see it, people don’t adopt mobile devices, they marry them. Some people spend more time with these devices than with any person in their lives, including their spouses”.

B. Improve Mobile loyalty and use it

• The more you interact the more you increase awareness to problematic behaviour

• Collaboration among users and computers: Human Computing a la Luis van Ahn to improve models of behaviour and Kairos

• Diary – microcontent datacollection• Evaluate the mobile loyalty from the

responses (Adaptable questionaires based on bayes)
