This tiny aroma diffuser clips to your shoulder bag or breast pocket.  Both the diffusion module and cotton soaked with a scent are built into the device, allowing free control over when to enjoy the scent with a simple on/off switch. The gadget was created along dual concepts, each reflecting varying conditions and differing aromas.

Concept 1:  To enjoy a completely new scent with greater freedom

Targets:

- people who wish to enjoy scents where they want and how they want

- people who wish to alter their scent to fit their mood in everyday scenarios

Happy users:

• those who are interested in fashion and in differing ways of expressing themselves
• men who ceased wearing scents as they disliked being unable to control their usage

Concept 2:　A new portable aroma diffuser which can change your mood

Conditions for use:

• when the user loses concentration during work
• people who need a soothing moment, such as just before giving an oral presentation
• when the user wishes a heightened sense of relaxation

Happy users:

• those losing concentration during long hours of deskwork, pre-exam students needing motivation, and engineers
• salesmen suffering a fit of anxiety just as they are about to face a moment of truth at work, such as making a key presentation (can use this to relax)
• women wishing a heightened sense of relaxation while enjoying reading or listening to music out somewhere

- Circuit design, parts selection, survey concerning the scent(s):  Scents with academically-demonstrated results (partially established at this time)

-  A small, thin prototype for user evaluation

- New guidelines for improvement based on user feedback from the prototype: We plan to conduct testing followed by a survey of target users over a fixed interval. Then, we will conduct a principal component analysis to estimate the appropriate level for features and components, using the results in a final version of the gadget.
