Abstract: 

Traditional industrial design focuses on a product's functionality and its physical features, while today's design requires different perspectives and approaches for increasingly complex design problems. Therefore, the attention of designers is shifting from mere usability and efficiency to playful, explorative, pleasure and emotion. Over the last decade, new opportunities have emerged for designers to create technological systems that engage nearly every aspect of human experience. Interaction design represents the embedding of information technology into new territories of our everyday life. It is commonly viewed as a recent trend in human-computer-interaction that focused on designing user experiences with technology. It has been defined a shift of focus from what a thing does as we use it to what we do in the acts that define use. In other words, interaction design is a special method of design which want moved attention from the visual presentation of spatial form to the act presentation of temporal behavior. Interaction represents many behavior, communication and affection between human and product, human and system or human and human. Interaction design studies aims to investigate, evaluate and define these behaviors, affections and communications and trying to achieve desired performance and satisfaction for users. This method of design is a perspective of many diverse components like culture, perceptual information, sensation, essence, material, function and feeling. As a matter of fact in interaction design theories, a designer should study and explore much more than just product's function. One of the most branches to be studied in the field of interaction design is perceptual information which includes physical interaction. Hand tool, widely home-used are the range of products that just for their industrial and outlook can't be interacted appropriately by an individual home-user. Therefore, a hand tool drill is used as a case study in this paper to find how different perceptual information can be presented in product parts. This part of our study includes two phases, "user task analysis" and "usability evaluation". In this regard, there are three different and important roles in assisting user operations which used in our study to evaluate user operation tasks: "behavioral information", "conventional information", and "assemblage information". When the subjects performed the main tasks, operational processes were clearly investigated. Ten subjects participated in this study and were asked to perform the tasks and then determined subjective evaluation. A seven-level Likert scale was used to measure the difficulty level of each subtask in the current study. The data from observations were analyzed principally based on the way users operated the hand tool drill and its related parts. All finding and results indicated that drill's industrial aspect from view point of form and colors, and other product specifications such as heavy, loud sound, needed to precise control due to high speed, were most important factors which have affect to interaction between human and product. This paper demonstrates perceptual information approaches to understanding variety aspects of interaction design and incorporating them into design processes. However, research in this domain is still in an exploratory stage.
