The progress of this program is summarized for each of the four major working items.
1. Kansei database: A data schema for representing the relationship between human senses and product features was designed and partially implemented. The database has a three-layered structure to accommodate physical parameters, Kansei indices, and delight indices so that the delight indices can be derived from the physical properties. This date schema is tested by implementing a database and storing Kansei indices and delight indices for sound made by products. The schema is considered valid for such applications.
2.Kansei Modeling: The specifications of the Kansei modeling framework were examined. The test prototyping of a Kansei model for a target product was conducted on the MBD (Model Based Design) framework. An interface layer was incorporated between the physical model and the Kansei model (Kansei indices and delight indices) to enable computation of the delight factors of products by the delight indices. A prototype Kansei model was implemented for the sound made by hair dryers.
3.Kansei Integration: Software for extending the base tools of the System Planner for Kansei modeling was developed. In particular, an interface from the System Planner to XVL and also one to Icepak (ANSYS) were implemented. They are useful for designing electric circuits as they allow preliminary functional evaluation of the target product. In addition, a function to import MBD data (Modelica data) was also implemented. This function requires mapping of elements of MBD to those of the System Planner. As mapping is not so straightforward, further investigation is needed. The GUI for this Kansei integration of mechanical CAD tools was partially prototyped.
4.Kansei Reverse Engineering: In order to import dense mesh models to XVL from 3D scanners, a function was developed to reduce the number of elements. The current software module in XVL must be extended so as to handle extremely large-scale data in terms of efficient memory usage and fast computation.Further developments will be carried out in 2015. Another working item was to introduce an XCT system. The performance of some industrial XCT systems was evaluated by scanning typical product specimens to determine their specifications. The scanned data was also used for typical reverse engineering operations such as surface extraction, part segmentation, etc. These operations were manually applied to confirm the quality of the scanned data.
5.Demonstration project: A demonstration project for evaluating the functionality and applicability of the platform was started. The objective is to develop a device to help disabled persons get up easily from bed and move to their desired destination. A preliminary field study was conducted to analyze the requirements.
