Computer Program Product, Device, System and Method for Gathering Respondent Input

A computer program product for gathering respondent input for determining a ranking of a plurality of states each characterized by a set of selected levels each associated to an attribute of a set of attributes associated to said state, the computer program product being in microprocessor readable form and arranged for, when stored in a memory of a device, further comprising a display, a communication port and a microprocessor for controlling the display and arranged for communicating, via the communication port, with a central computer and when executed by said microprocessor:

• causing said display to show the attributes of said set and allowing selecting respondent levels for said attributes;
• storing said set of selected respondent levels for said attributes as a respondent state;
• determining a plurality of alternative ones of said states in accordance with said respondent state or outputting said respondent state to the central computer and receiving back a plurality of alternative ones of said states determined in accordance with said respondent state by said central computer;
• causing said display to show each of said determined alternative states as the set of attributes with the associated set of alternative levels simultaneously and with at least one input field for inputting a preference indication of the shown alternative state compared with the respondent state on said display;
• and
• outputting the respondent state and inputted respondent preference indications compared with the respondent state for each of said determined alternative states to the central computer.
