Stakeholders consider aesthetics and sustainability as important aspects of over-the-counter pharmaceutical (OTCP) packaging, and studies show that their interests should be represented more. To address this, a framework which supports designers to develop aesthetically pleasing sustainable OTCP packaging was generated, keeping at its core the stakeholders. The requirements were identified, leading to the architecture development and implementation in a prototype tool. Results provide a degree of evidence that the framework contributes to a user-centred design approach for OTCP packaging.

The role of toys in early childhood intervention is crucial for children to acquire and improve their skills. A study with preschool children has been carried out in order to establish, from a product design perspective, how toys' innate characteristics trigger toy preferences. It was found that children's preference is presided by the play value that is perceived. By exploiting hedonic and pragmatic qualities, designers can embed persuasive qualities in toys. A framework for toy design is proposed as a model for a computer-aided support tool that helps toy designers reach their design goal.

This paper describes the work carried out on off-line paper based scribbles such that they can be incorporated into a sketch-based interface without forcing designers to change their natural drawing habits. In this work, the scribbled drawings are converted into a vectorial format which can be recognized by a CAD system. This is achieved by using pattern analysis techniques, namely the Gabor filter to simplify the scribbled drawing. Vector line are then extracted from the resulting drawing by means of Kalman filtering.

Permanent Influence of Sketch Types on Distributed Design Team WorkProduct development is a collaborative activity more often than ever carried out by distributed design teams. It is critical to determine how sketches are used in such environments in order to improve the design process. Sketches produced by students participating in a collaborative design project of three European Universities are classified according to the intention of the designer when producing a sketch, the level of detail shown in the sketch and the phase when the sketch was produced. The adapted classification system used in this paper helps to analyse type of sketches with most variety of ideas. Furthermore, this paper reviews which type of sketches offer the most potential to be further developed.Results show that persuasive sketches offer the broadest range of ideas since they are produced as a combination of ideas from brainstorming sessions. Shared sketches help to achieve consensus in decision making since the sketches are most likely to be produced by the entire group rather than individually.

Understanding the viewpoint of clinicians in a healthcare setting is a vital task to comprehend the success of patients undergoing physical rehabilitation. Addressing user experience is an essential activity which designers undertake when formulating product specifications at the early stages of product design. The involvement of clinicians during the product use-phase influences the progress and achievements attained by the patients throughout their rehabilitation journey. Several clinicians (n=16) were asked to participate in a qualitative study to evaluate the performance of different personae in activities of daily living. The experiences of patients who use rehabilitation products as part of their therapy session at the clinic were evaluated. Based on this evaluation, a set of clinician requirements were formulated to reflect the overall experience when using rehabilitation products. Understanding these requirements brought about several implications to be considered during the design cycle. Through these considerations and by adopting a user-centred design approach, designers are in a better position to design innovative products targeted at providing a high-quality user experience which increases customer satisfaction.
