A decision support system (DSS) for avoiding obesity was developed and evaluated in two facets,
which were user friendliness and usefulness consisted of five-level Likert items (1= Strongly
disagree,2=Disagree, 3=Neutral, 4=Agree, 5=Strongly agree) participated by 78 responses on online
questionnaire. The DSS works by letting the user to select the food menu(s) and the number of each menu
that they wanted in a day. Then DSS calculated total energy of all the menus selected and showed the total
energy. After that, user selected his/her sex, and DSS would compare the total energy with the range of
energy required per day for the user’s sex and showed the result in three cases: 1) too much 2) ok 3) less.
The results from evaluation of DSS participated by 78 responses were presented that user friendliness was
average (4.44), and usefulness was average (4.60). |
