“…Thus, one way to increase attractive of the speaker is, we can morph from oval shape to either circle or horizontal oval. Furthermore, Log-Aesthetic curves [11] can be used to design the body shape instead of NURBS that suits better for industrial design purposes.…”

Abstract.The first stage of product design is a simple sketch by a stylist. The attributes of the product can easily be expressed using words, for example, thin and sharp. This paper delves into a preliminary stage of product design based on the needs of potential customers. Taking into consideration of an anatomy of a speaker as a case study, we first classify its main attribute which attracts potential customers. These attributes are expressed using appropriate semantics which is represented with suitable variations of words. It is then distributed to potential customers. The survey data is then represented with soft set. The set of attributes which represent potential customers' preference are identified by modifying existing soft set decision making algorithm to suit product design environment. The final results show a set of attributes for mass manufacture and the importance of each attributes were also identified.

The quality of a curve for industrial design and computer graphics can be interrogated using Logarithmic Curvature Graph (LCG) and Logarithmic Torsion Graph (LTG). A curve is said to be aesthetic if it depicts linear LCG and LTG function. The Log-aesthetic curve (LAC) was developed bearing this notion and it was later extended to a Generalized Log-aesthetic curve (GLAC) using the -shift and -shift approach. This paper reformulates GLAC by representing the Logarithmic Curvature and Torsion graph's gradient function as a nonlinear ordinary differential equation (ODE) with boundary conditions. The outputs of solving the ODEs result in a well defined Cesaro equation in the form of curvature function that is able to produce both planar as well as spatial curves with promising entities for industrial product design, computer graphics and more.

“…They further illustrated the maturity of this algorithm by showing its application in automobile design [14]. Readers are referred to an extensive review on aesthetic curves and surfaces [15]. In essence, the curve synthesis process involves double integration of user defined curvature function in order to derive the formulation of the curve.…”
