“…Additionally, tools to assess the individual learning progress can be integrated. Early in the development process, quality criteria will be taken into account for the use of online courses and web applications, such as consistency, user control, ease of learning, flexibility, error management, user help and user guidance responsiveness [ 49 ]. A test module will be developed to assess usability.…”

BackgroundIn Germany, the guardianship system provides adults who are no longer able to handle their own affairs a court-appointed legal representative, for support without restriction of legal capacity. Although these representatives only rarely are qualified in healthcare, they nevertheless play decisive roles in the decision-making processes for people with dementia. Previously, we developed an education program (PRODECIDE) to address this shortcoming and tested it for feasibility. Typical, autonomy-restricting decisions in the care of people with dementia—namely, using percutaneous endoscopic gastrostomy (PEG) or physical restrains (PR), or the prescription of antipsychotic drugs (AP)—were the subject areas trained. The training course aims to enhance the competency of legal representatives in informed decision-making. In this study, we will evaluate the efficacy of the PRODECIDE education program.MethodsA randomized controlled trial with a six-month follow-up will be conducted to compare the PRODECIDE education program with standard care, enrolling legal representatives (N = 216). The education program lasts 10 h and comprises four modules: A, decision-making processes and methods; and B, C and D, evidence-based knowledge about PEG, PR and AP, respectively.The primary outcome measure is knowledge, which is operationalized as the understanding of decision-making processes in healthcare affairs and in setting realistic expectations about benefits and harms of PEG, PR and AP in people with dementia. Secondary outcomes are sufficient and sustainable knowledge and percentage of persons concerned affected by PEG, FEM or AP. A qualitative process evaluation will be performed. Additionally, to support implementation, a concept for translating the educational contents into e-learning modules will be developed.DiscussionThe study results will show whether the efficacy of the education program could justify its implementation into the regular training curricula for legal representatives. Additionally, it will determine whether an e-learning course provides a valuable backup or even alternative learning strategy.Trial registrationTRN: ISRCTN17960111, Date: 01/06/2017.

“…Then, the collection of user and expert feedback after ideating and modeling in the idea implementation stage allows converging to a final solution in the finalization stage [33]. The process is highly couplable with user-centric usability design principles such as visibility of system status, match between system and the real world, user control and freedom, flexibility, and efficiency of use [39]. Moreover, the four stages are termed discovery, define, develop, and deliver [37].…”

This paper presents the analysis and design of a new, wearable orientation guidance device in modern travel aid systems for blind and visually impaired people. The four-stage double-diamond design model was applied in the design process to achieve human-centric innovation and to ensure technical feasibility and economic viability. Consequently, a sliding tactile feedback wristband was designed and prototyped. Furthermore, a Bezier curve-based adaptive path planner is proposed to guarantee collision-free planned motion. Proof-of-concept experiments on both virtual and real-world scenarios are conducted. The evaluation results confirmed the efficiency and feasibility of the design and imply the design’s remarkable potential in spatial perception rehabilitation.

To investigate and compare the common features and differences of the cognitive processes, during which interfaces with diverse similarities are evaluated, this article chose the color code and layout forms of digital interface to carry out further research. The study adopted the visual Oddball experimental paradigm that was based on the event-related potential technique and integrated the behavioral and event-related potential data to analyze the neural features of the cognitive process when two coding forms were individually processed. The result reveals that there were P300 components, elicited by the target stimuli, in both of the two experiment sessions. The average amplitude of P300 positively correlates the similarities between the target and standard stimuli, with its latency positively correlating the overall complexity of the stimuli. In the color experiment session, there was apparent visual mismatching negativity around 200 ms after the present of the target, which is related with the early attention. The empirical significance of conclusions drawn in this study is listed as follows: first, it can help to effectively evaluate the usability of guiding features in the digital interfaces through the investigation on visual mismatching negativity elicited in the early attention process; second, the amplitude and latency of the P300 component can be applied in the evaluation and filtering of design schemes, which is based on the similarities perceived in the iterative process and this would enhance efficiency of user interface designers.
