Anyelir Cake And Bakery is the largest cake shop in Purwakarta which is engaged in the production of various kinds of cakes.  In the process of distributing products from the central store to branch stores, they still use WhatsApp to place orders. This causes frequent discrepancies in the number of products requested and the number of products received due to an error in reading the message. In this study, a mobile-based application will be built that is able to manage order data more accurately. The development of this application uses the User Centered Design (UCD). This is a design method that focuses on user needs so that the final result of this application does not need to change user behavior when using the application. The UCD method consists of four stages, namely plan the human centered design, specify user and organizational requirements, product design solutions, and evaluate design against user requirements. In the development process, application testing was carried out to get feedback from users with good scores, namely an average of 4 (agree) and 5 (strongly agree). This shows that the application is in accordance with the needs of the user.

Crossover Method

We apply an interactive genetic algorithm (iGA) to generate product recommendations. iGAs search for a single optimum point based on a user’s Kansei through the interaction between the user and machine. However, especially in the domain of product recommendations, there may be numerous optimum points. Therefore, the purpose of this study is to develop a new iGA crossover method that concurrently searches for multiple optimum points for multiple user preferences. The proposed method estimates the locations of the optimum area by a clustering method and then searches for the maximum values of the area by a probabilistic model. To confirm the effectiveness of this method, two experiments were performed. In the first experiment, a pseudouser operated an experiment system that implemented the proposed and conventional methods and the solutions obtained were evaluated using a set of pseudomultiple preferences. With this experiment, we proved that when there are multiple preferences, the proposed method searches faster and more diversely than the conventional one. The second experiment was a subjective experiment. This experiment showed that the proposed method was able to search concurrently for more preferences when subjects had multiple preferences.

Summary Background: Early involvement of stakeholders in the design of medical software is particularly important due to the need to incorporate complex knowledge and actions associated with clinical work. Standard user-centered design methods include focus groups and participatory design sessions with individual stakeholders, which generally limit user involvement to a small number of individuals due to the significant time investments from designers and end users. Objectives: The goal of this project was to reduce the effort for end users to participate in co-design of a software user interface by developing an interactive web-based crowd- sourcing platform. Methods: In a randomized trial, we compared a new web-based crowdsourcing platform to standard participatory design sessions. We developed an interactive, modular platform that allows responsive remote customization and design feedback on a visual user interface based on user preferences. The responsive canvas is a dynamic HTML template that responds in real time to user preference selections. Upon completion, the design team can view the user’s interface creations through an administrator portal and download the structured selections through a REDCap interface. Results: We have created a software platform that allows users to customize a user interface and see the results of that customization in real time, receiving immediate feedback on the impact of their design choices. Neonatal clinicians used the new platform to successfully design and customize a neonatal handoff tool. They received no specific instruction and yet were able to use the software easily and reported high usability. Conclusions: VandAID, a new web-based crowdsourcing platform, can involve multiple users in user-centered design simultaneously and provides means of obtaining design feedback remotely. The software can provide design feedback at any stage in the design process, but it will be of greatest utility for specifying user requirements and evaluating iterative designs with multiple options.

BACKGROUND Despite the potential value of assistive technology to support people with dementia (PWD) in everyday activities, use of these technologies is still limited. To ensure that assistive technologies better address the specific needs and daily context of PWD and their informal caregivers, it is particularly important to involve them in all different phases of assistive technology development. The literature rarely describes the involvement of PWD throughout the development process of assistive technologies, which makes it difficult to further reflect on and improve active involvement of PWD. OBJECTIVE This two-part study aimed to gather insights on the user-centered design (UCD) applied in the development process of the alpha prototype of the serious game PLAYTIME by describing the methods and procedures of the UCD as well as evaluating the UCD from the perspective of all involved stakeholders. METHODS The first three phases of the user-driven Living Lab of Innovate Dementia 2.0 were applied to directly involve PWD and their informal caregivers through qualitative research methods, including focus groups and a context-field study, in the development of the alpha prototype of PLAYTIME from exploration to design to testing. After the testing phase, a total number of 18 semi-structured interviews were conducted with PWD, their informal caregivers and the project members of PLAYTIME to evaluate the applied UCD from the perspective of all involved stakeholders. The interviews addressed five of the principles for successful UCD and the appropriateness of the different methods used in the focus groups and context-field study. RESULTS Results of the interviews focused, amongst others, on the level of involvement of PWD and their informal caregivers in the development process, the input provided by PWD and their informal caregivers, the value of early prototyping, continuous iterations of design solutions and in-context testing, the role of dementia care professionals in the multidisciplinary project team, and the appropriateness of open- and closed-ended questions for obtaining input from PWD and their informal caregivers. CONCLUSIONS The description and evaluation of the UCD applied in the development process of the alpha prototype of PLAYTIME resulted in several insights on the relevance of UCD for all involved stakeholders as well as how PWD can be involved in the subsequent phases of usable and meaningful assistive technology development.
