remote Paper Prototype testing
Human Factors in Computing Systems, 2015Co-Authors: Kevin Chen, Haoqi ZhangAbstract:To test Paper Prototypes of mobile applications, we have been experimenting with remote Paper Prototype testing as an approach and tool for enabling a designer to wizard a Paper Prototype from afar while a user tests the Prototype out of the lab. This Paper presents a system for remote Paper Prototype testing that consists of (1) a video camera placed over a Paper Prototype, which streams a live audio-visual feed via Google Hangouts to a tester, and (2) Google Glass on the tester, which streams a live audio-visual-data feed to the facilitator and wizard. Results from a pilot study found that remote Paper Prototype testing helped designers gain valuable insights through use in realistic scenarios.

Chapter 4 – Making a Paper Prototype
Paper Prototyping, 2020Co-Authors: Carolyn SnyderAbstract:This chapter explains the process of creating Paper Prototype, the widget-level view of Paper Prototypes and the ways to include interaction, help/documentation, and hardware. It illustrates a Prototype of a screen used to create a rule for filtering email. As the user selects each “Condition and Action,” the Computer writes it on removable tape and places it at the bottom. After the user clicks on the link and selects a name from the address book, the computer places another piece of tape on top of the specific word to show the selected name. In this manner, the user sees the rule being built as one component at a time, much as it appears on a computer. A well defined list with name, purpose, and explanation of things that a user requires to design a Paper Prototype is presented. Because the Paper prototyping aims at simulating almost anything out of imagination, there are many aspects of human-computer interaction that a human being can simulate well enough through feedbacks from usability tests.

Chapter 16 – Final Thoughts
Paper Prototyping, 2020Co-Authors: Carolyn SnyderAbstract:Publisher Summary This chapter provides a short, thought-provoking list of unanswered questions about Paper prototyping. It includes the ways Paper prototyping change the process of design, whether it allows the designers to work in a fundamentally different way, whether the benefits of using Paper Prototypes in usability tests depend more on the medium of Paper or the unfinished nature of the design, the ways a Paper Prototype affect a user's behavior compared to testing the real thing, the best ways to funnel the results from Paper Prototype testing into the development process, and whether there is a better way to spot false problems due to the Paper Prototype or computer. An introduction to usability testing is also given.

Chapter 14 – When to Use Paper
Paper Prototyping, 2020Co-Authors: Carolyn SnyderAbstract:Various circumstances of a project, staff, and development environment can affect the decision of whether to test with a Paper Prototype. This chapter examines whether testing a Paper Prototype would make sense for a project as opposed to testing some other version of interface. Remote usability testing is an intriguing idea, but it may not yield the richness of data that a user can get by being in the same room with users. There may be interaction drawbacks if the user has to flip pages or take other special action to get to the next screen. On the other hand, if travel isn't feasible, remote testing is much better than nothing and it may allow the product team to get feedback from a larger number of users than they’d be able to see in person. Paper Prototypes do not rely on databases, networks, servers, or any other form of technology, which eliminates most of the things that can go wrong. If a user is concerned that a buggy interface will be too distracting to the product team (or upsetting to users, who may disregard assurances that it isn't their fault), using a Paper Prototype instead can be considered.

Preparing the Prototype
Paper Prototyping, 2020Co-Authors: Carolyn SnyderAbstract:This chapter describes the process of creating a Paper Prototype around a set of usability tasks and holding internal walkthroughs to prepare for usability testing. It explains the ways to create a Paper Prototype and prepare for usability testing by doing walkthroughs. The Prototype creation and walkthrough activities happen iteratively—making some Prototype pieces, doing a walkthrough, figuring out what's wrong or missing, and repeated. Often it's important for users to see the way their data will appear elsewhere in the system. If a user is creating an online classified ad by filling out a form, he/she will probably want to preview that ad in the same format the system will use to display it. The data use should be realistic enough so that the users can interact with it in a meaningful way. This is especially important when users are domain experts in the subject matter of the interface.

usability testing with a Paper Prototype
Paper Prototyping#R##N#The Fast and Easy Way to Design and Refine User Interfaces, 2004Co-Authors: Carolyn SnyderAbstract:It's not necessary to have a usability lab to test a Paper Prototype. The main purpose of usability testing is to provide data to other members of the team so that they can make the product better. The biggest problem with usability labs is that some are optimized for computer-based testing—the rooms are small, or there is restrictive furniture (such as a kneehole desk) that makes it hard for several people to gather around. This chapter discusses the things that the facilitator and computer should do in a Paper Prototype usability test. The ways he/she sets up the room, greets users, introduces the concept of Paper prototyping, and facilitates the session are all important. The facilitator can sit either next to the users or across the table, next to the computer. It's easier for the facilitator to converse with users when they’re across the table, but there may be a subtle psychological benefit to having the facilitator literally “on the users” side.” In addition, videotaping a Paper Prototype should be skipped if possible; a computer- based test is considered as a better option.

The influence of user expertise and Prototype fidelity in usability tests
Applied Ergonomics, 2010Co-Authors: Jürgen Sauer, Katrin Seibel, Bruno RuttingerAbstract:An empirical study examined the impact of user expertise and Prototype fidelity on the outcomes of a usability test. User expertise (expert vs. novice) and Prototype fidelity (Paper Prototype, 3D mock-up, and fully operational appliance) were manipulated as independent variables in a 2 × 3 between-subjects design. Employing a floor scrubber as a model product, 48 users carried out several cleaning tasks. Usability problems identified by participants were recorded. Furthermore, performance, system management strategies and perceived usability were measured. The results showed that experts reported more usability problems than novices but these were considered to be less severe than those reported by novices. Reduced fidelity Prototypes were generally suitable to predict product usability of the real appliance. The implications for the running of usability tests are specific to the fidelity of the Prototype. © 2009 Elsevier Ltd. All rights reserved.

Prototype is created from MOSFETs and microcontroller structure it allows really low price of whole Prototype. The Prototype is designed so that it can be used for different powers of induction generator and different weather conditions. The Prototype has got self education program for learning of optimum of induction generator.
