Abstract Introduction Gathering end-user feedback about candidate technologies in the operational environment prior to fielding helps to ensure that far-forward medical teams receive the most suitable technology. It is therefore a crucial step in the defense medical acquisition process. The current article reviews the methodology and provides an illustrative example of how end-user feedback was collected to evaluate the current suitability and future promise of two FDA-approved devices, the BrainScope One and Infrascanner 2000, that could potentially aid in the field evaluation of head injuries by far-forward medical teams. Materials and Method The BrainScope One and Infrascanner 2000 end-user evaluation is used as an example to illustrate how to collect end-user feedback from the field in order to rapidly assess the candidate technology. In this evaluation of whether and how to implement FDA-approved technology candidates for head injury assessment by far-forward medical teams, end-user feedback was collected from 158 medical personnel at 8 bases in Afghanistan, Iraq, and Kuwait using focus groups and interviews. Results The end users reported consistent concerns about the operational efficacy and suitability of the current versions of the devices as well as the areas where the devices showed promise for the Department of Defense (DoD). End-user feedback is shown in detail to demonstrate the depth and richness of feedback that can be gathered using this methodology. Conclusion Overall, the BrainScope One and Infrascanner 2000 end-user evaluation shows the necessity and value of gathering end-user field efficacy and suitability feedback during the medical acquisition process. Limitations and best practices for this approach are discussed.

Payment Credit

Micro-payment systems are becoming an important part of peer-to-peer (P2P) networks. The main reason for this is to address the “free-rider” problem in most existing content sharing systems. The authors of this chapter have developed a new micro-payment system for content sharing in P2P networks called P2P-Netpay. This is an offline, debit based protocol that provides a secure, flexible, usable, and reliable credit service in peer-to-peer networks ensuring equitable participation by all parties. The authors have carried out an assessment of micro-payment against non-micro-payment credit systems for file sharing applications. The chapter reports on the design of our experiment and results of an end user evaluation. The chapter then discusses the performance of the credit model, comparing it to a non-micro-payment credit model. Through evaluation of the proposed system and comparison with other existing systems, the authors find that the new approach eliminates the “free-rider” problem. The chapter analyses a heuristic evaluation performed by a set of evaluators and presents directions for research aiming to improve the overall satisfaction and efficiency of this model for peers.

This paper reports the results of a survey of 1500 US graphic designers. Respondents provided information about their levels of involvement with project-related information gathering and analysis, planning, and end-user evaluation. While there are significant levels of involvement in some of these activities, comments made by respondents reveal that involvement with information gathering and analysis, planning, and end-user evaluation is mostly informal. That is, they are often conducted without a formal methodology, and are often not mentioned in project proposals and other related documents. This suggests an opportunity for graphic designers to adopt a formal method for incorporating information gathering and analysis, planning, and end-user evaluation in their design processes. This could allow graphic designers to construct a process comparable to more respected professions, and should promote design solutions geared more closely to the needs of audiences. There is still much room for improvement in the areas of information gathering and analysis, planning, and end-user evaluation in the practice of graphic design.

Relative accessibility is a widely studied approach that recognizes access to major locations as subjective and shaped by individual circumstances (e.g., individual preferences, habits, and cultural norms). One missing element in the knowledge base is how relative accessibility can be effectively mapped for decision-making. To fill the research gap, this paper evaluates whether cartograms are an appropriate tool for mapping relative accessibility, taking the city of Zaragoza, Spain as a case study. The research design included three phases: (i) elaboration of grid-based maps on relative non-motorized accessibility; (ii) elaboration of cartograms on relative non-motorized accessibility; (iii) an end-user evaluation with 30 local practitioners to analyze the effectiveness of cartograms to map relative accessibility compared to grid-based maps. Participants signaled that diffusion-based cartograms could be complementary to grid-based maps, providing better visualization of spatial dissimilarity patterns of accessibility between population groups. However, participants noted greater difficulty in identifying Dorling cartograms as an effective technique for mapping relative accessibility. The paper closes with a review of the strengths and weaknesses of the potential application of these visualization techniques in the field of accessibility planning.
