In this work, the creator opens up a new field in game software with a totally new style of “oryori navigator” (cooking navigator) by combining a new presentation method and technology. Explanation of the cooking by charming synthetic voice and the presentation and technology which made it possible to teach the steps of cooking by voice recognition are wonderful. The idea where, even though the user’s hands are wet, or full when they are in the middle of cooking, they can move to the next step by just saying “OK” with their voice, accurately captures users’ needs.
