- W2585545864 abstract "This report is the result from an Integrated Product Design graduation project entitled ‘The Next Generation EnergyLight’. It describes the user-centered research and product development process of a new generation light therapy products. Philips EnergyLight currently sells three light therapy products that claim to make you ‘feel more energetic throughout the day, in a natural way’. The product is mainly targeted at people suffering from Seasonal Affective Disorder (SAD; known as winterdepression) and sub-syndromal Seasonal Affective Disorder (sub-SAD; known as winterblues). The goal of the project was to identify opportunities for a new generation of EnergyLight focused on this consumer group. At the start of the project, an analysis was performed containing a scientific, consumer and market research part. The scientific research consisted of a literature study on SAD, complemented with expert interviews. It was concluded that light therapy is a proven treatment for (sub)SAD, but in order to be effective and safe it should be used properly (correct distance, light intensity, and duration of use) and in a controlled way. However, from existing consumer research, user interviews and a survey, it was found that users often use the product improperly (e.g. the product is used at a too low intensity, too large distance, too short duration or in the evening). The consumer research also indicated several user concerns of the current products (e.g. the bright light is not comfortable and users feel socially embarrassed to use the product) and user preferences for future use (e.g. use at home while having breakfast, using computer or watching television). The market research showed there is a significant growth potential for EnergyLight, although awareness of the products and especially the transition into purchase intent is limited, partly because people think the products are rather expensive and because they are not convinced that the light will help treating their complaints. The total consumer group was subdivided into two main focus areas, represented by the personas ‘Arjen’ and ‘Bridget’. Seven search areas for these personas were indicated as being promising for future product and business developments. From the formulated design brief, several sub-problems were indicated. Three user tests, principle solutions and technical research helped in making decisions on these sub-problems. Ideas were generated by means of brainstorming and sketching, which resulted in the development of four concepts. These concepts differed in their overall orientation (medical or lifestyle) and extended functionalities and intended use scenario. Furthermore, a support path for informing the consumer was proposed, including a software application that could provide a personal advice. Out of the four concepts, the SunSphere concept was chosen as the concept to optimize into a preliminary design, which was further translated into a prototype. The product was evaluated with users, engineers and clinicians. The results suggest that users appreciate the product in terms of design, use scenario and light output. Together with the integration of two light settings and distance sensing the participants indicated that the product has clear added values that are likely to validate the indicated sales price. From a business perspective, the product has the potential to replace the current EnergyLight products and differentiate from competitors by means of aesthetics, light output and additional functions. The user interface could be improved from the prototype in terms of ‘learnability’, because without extended instructions not all functions were clear yet. From the expert interviews it was concluded that the functions and adjustments for stimulating proper use, combined with the software application could increase correct and safe use at home. The SunSphere is a showcase of how the findings from consumer, market and scientific research could be translated into one product. However, several key elements could also be applied (separately) in other future embodiments for EnergyLight. Therefore it is recommended to Philips to especially understand the fundamental elements and rich consumer insights of this project, because these will be valid in most embodiments and propositions for future EnergyLight products." @default.
