Data graphics can be a powerful aid to decision-making—if they are designed to mesh well with human vision and understanding. Perceiving data values can be more precise for some graphical types, such as a scatterplot, and less precise for others, such as a heatmap. The eye can extract some types of statistics from large arrays in an eyeblink, as quickly as recognizing an object or face. But perceiving some patterns in visualized numbers—particularly comparisons within a dataset—is slow and effortful, unfolding over a series of operations that are guided by attention and previous experience. Effective data graphics map important messages onto visual patterns that are easily extracted, likely to be attended, and as consistent as possible with the audience’s previous experience. User-centered design methods, which rely on iteration and experimentation to improve a design, are critical tools for creating effective data visualizations.

Business Placement Center membantu mengelola website alumni dalam memenuhi kebutuhan alumni salah satunya memberikan informasi mengenai lowongan pekerjaan. Website Alumni Amikom sudah memberikan informasi mengenai lowongan pekerjaan. Namun website alumni masih perlu ditambahkan fitur-fitur menu penunjang dalam mempermudah pencarian informasi pekerjaan yang sesuai keinginan pengguna. Penggunaan metode User Centered Design untuk mempermudah pengguna dalam menggunakan fasilitas yang ada pada website ketika mencari informasi lowongan pekerjaan dan pengguna berperan penting dalam setiap proses UCD. Dengan pendekatan User Centered Design diharapkan dapat menghasilkan tampilan dan fungsionalitas yang maksimal pada rancangan sistem yang dibangun sehingga sesuai dengan kebutuhan pengguna. Metode penelitian yang dilakukan yaitu observasi, wawancara dan kuesioner untuk mengetahui kebutuhan pengguna. Analisis dan perancangan menggunakan pendekatan User Centered Design dan implementasi perancangan sistem. Hasil penelitiannya adalah pengguna merasa nyaman dengan tampilan antarmuka website yang sudah dibangun, informasi yang disajikan mudah dipahami dan fitur-fitur menu sudah berhasil berjalansesuai fungsi.Business Placement Center help manage the website for the needs of alumnus one of them is to provide information on a vacancy. The alumnus website’s provides information about job vacancy. The website still need the support to facilitate the searching all the features the work in accordance with what the use. The method of user centered design to make it easy for users in the use of the existing facilities at the website while searching for information a vacancy and users play an important role in any proses UCD. User Centered Design approach is expected to produce the interface and functionality maximal built in the system so that in accordance with the need of users. Research methodology was by observation, interviews and quesionnaires to find out the need of users. Analysis and design using UCD approach and implementation of the system. The results of research is users feel comfortable with a display interface of website which have been built, the information is easily understood and menu features has been successfully run a function.

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.

BACKGROUND Mobile health (mHealth) systems have been shown to be useful in supporting self-management by promoting adherence to schedules and longitudinal health interventions, especially in people with disabilities (PwD). The Interactive Mobile Health and Rehabilitation (iMHere) System was developed to empower PwD and those with chronic conditions with supports needed for self-management and independent living. Since the first iteration of the iMHere 1.0 app, several studies have evaluated accessibility and usability of the system. Potential opportunities to improve and simplify the user interface (UI) were identified, and the iMHere modules were redesigned accordingly. OBJECTIVE The aim of this study was to evaluate the usability of the redesigned modules within iMHere 1.0. METHODS This study evaluated the original and redesigned MyMeds and SkinCare modules. To assess the participants’ dexterity levels, the Purdue Pegboard Test (PPBT) was administered. Participants were then asked to perform a set of tasks using both the original and redesigned MyMeds and SkinCare modules to assess efficiency and effectiveness. Usability was measured using the Telehealth Usability Questionnaire (TUQ) to evaluate 10 new accessibility features that were added to the redesigned app. Participants were also asked which version they preferred. RESULTS Twenty-four participants with disabilities and varied degrees of dexterity impairments completed the entire study protocol. Participants displayed improved efficiency and effectiveness of use when using the redesigned modules, as compared to the original modules. Participants also reported improved usability and preferred the redesigned modules. CONCLUSIONS This study demonstrated that the iMHere System became more efficient, effective, and usable for individuals with dexterity impairments after redesigning it according to user-centered principles.
