Because of tough competition, companies attempt to present attractive products for consumers. Cultural design approach is used by several companies to develop products which based on consumers’ cultures. While same cultural product are sold in different countries because of globalization, there is a need for a new approach to design cultural products to be more attractive for consumers from different cultures. As emotion is the key motivation for people while judging things and making buying decisions, emotional design can be considered a good approach for design cultural products. This paper aims to integrate emotional and cultural design processes to help designers to create emotional interaction between the consumer and the cultural products. This interaction can push consumers to buy specific products more than others. The paper firstly reviews emotional and cultural design, cultural features, and design process. Afterward, a framework is developed to describe how emotions can be embedded in cultural design process.

Designing of products typically proceeds through a number of stages to be manufactured. Conceptual design is considered the most important stage within design as idea generation process takes place. When it comes to idea generation process, the first thing comes to the mind is sketching which is used by designers to investigate ideas and visualize them. This is because most of designers use it, design schools work hard to improve their students' sketching skills, and companies and design studios produce sketches to persuade their clients. It seems sketching is the only technique to generate ideas, but it is not. There are various techniques were developed by designers or within other domains such as economic and psychology. These techniques can be used individually and in a group such as brainstorming, mind map, written scenario and stepladder technique. This paper aims to explore different idea generation techniques, investigate how they work, and find a framework for these technique to work together to add more dynamic, speed, and creativity to idea generation process. It first review these techniques from different domains. Then, these techniques are analyzed and classified. In the last step, a framework for idea generation techniques is created to enable designers to benefit the best from different techniques.

In this early stage of the design process, designers have developed some ways to help them to explore designs in its early phases. Sketching is one of these methods. In this paper, a study of sketch nature was carried and a proposed sketch-based interface for modeling was designed. Sketch nature study investigated the cognitive activities in sketching process, analyzed sketches of design students and professional designers, and collected data about sketching process and sketch-based systems requirements from designers to develop sketching scenarios and determine sketch-based systems requirements. These requirements were used to design a proposed sketch-based system for conceptual design with a multi-windows approach. The proposed system aims to provide an easy way for designers to sketch freely and for ideas to flow easily by using a multi-windows approach for sketching, 3D generation and rendering.

Its ambiguity inspires designers with new and unexpected alternatives for design ideas which enhance creativity in conceptual design. Sketchbased modeling appeared as an easy way for 3D sketching to open the way for digitizing sketching process. For that reason it focused on developing techniques and algorithms of converting 2D sketches into 3D models rather than enhancing creativity in sketching process. In this paper we present a new design for a sketch-based modeling interface to enhance creativity by considering sketching as an idea generation method, not a drawing process. This was done by separating 2D sketching and 3D modeling into two windows to make designers focus on idea development rather than being distrusted by 3D model creation. This interface uses gesture-based approach in 3D modeling as this approach is better for achieving integration with commercial CAD systems for more effectiveness of sketch-based interfaces. A new positioning method was developed to help designers to locate 3D objects in the scene easily with friendlier gestures and more accurate gesture recognition algorithm.

For a complete digitalization, integration of sketch-based design modeling and commercial CAD systems is being a necessity. This is because of the need of detailed modification and refinement for the 3D models created by sketching. The integration can speed up the design process and affect competition between companies. In this paper, we present a new method to achieve the integration between sketch-based interfaces and commercial CAD systems by using gesturebased sketch modeling techniques for producing 3D conceptual design models and then translating the 3D models into CAD systems with feature recognition through IGES exchange files. Gesture-based modeling method was used because it works in a similar way to feature-based design approach and it is easy to extract features from its 3D models. IGES file format was used for exchanging 3D geometric model information because it is widely available within commercial CAD systems for data exchange and it also can express features and hierarchy information. 3D models were created with a gesture-based sketch interface for modeling and then information was extracted from it. After that, information was translated into IGES entities which were organized in a specific order in an IGES file. This information can be inputted into commercial CAD systems and recognized as a feature-based model with feature recognition embedded within CAD systems. To evaluate the proposed method, we conducted four case studies. In these case studies, we created 3D models and then transferred them into Autodesk Inventor as a commercial CAD system. After the CAD system recognized the 3D models successfully, we applied some modifications on the 3D models such as changing dimensions, positions and drafting to demonstrate the effective integration.
