PSSD Project (2011 – 2013, 2014 – 2016)

A similarity measurement framework of PSSD cases based on context-based activity model Design experience from previous design cases could help designers solving current design problems. Therefore, a case-based recommender system can recall suitable design cases for designers based on a similarity measurement mechanism. In the context of Product-Service System (PSS) design, the measurement of similarity between different cases [...]


Homo Minicus (2012 – 2016)

Bio-inspired Tech. on Demand Bio-inspired design was introduced as an alternative method to encourage breakthrough innovations during design projects by stimulating analogical reasoning and thinking of designers. However, the method did not perform as well as researchers expected because most designers, who are novices in the fields of biology and ecology, cannot infer the proper analogue (i.e. [...]


Style synthesis and analysis of car designs (2012-2016)

Style synthesis and analysis of car designs for style quantification Understanding how similar design appears is a key element to understanding companies’ design strategies. However, it is difficult to evaluate companies’ design strategies with conventional style measurement methods since they only taxonomically measure whether a specific characteristic is included in a specific style. This study numerically measured [...]


Theme Park Project (2013 – 2016)

Developing a case-based reasoning system to analyze environmental structures and soft services to support leisure space management Servicescape design of leisure spaces such as theme parks influence the level of visitor satisfaction and the re-visitation rate. However, only a few large theme park operators have a separate theme of specialists with heuristic knowledge for servicescaping. In response, small [...]


Image-based Tactile Emojis (2013 – 2015)

Image-based Tactile Emojis Improved Interpretation of Message Intention and Subtle Nuance for Visually Impaired Individuals To enhance missing nonverbal cues in computer-mediated communication using text, those who can see often use emojis or emoticons. Although emojis for the sighted have transformed throughout the years to animated forms and added sound effects, emojis for visually impaired people remain underdeveloped. [...]


Assessment of creativity in product design (2009 – 2013)

A quantitative approach for assessment of creativity in product design Most of the assessment of creativity in product design is based on the outcome, not the design process from which the creative ideas are derived. In this paper, we revealed the correlation coefficient of 20 factors critical in the product design process and the quality of design creativity [...]
