From Research Prototype to Research Product

Prototypes and prototyping have had a long and important history in the HCI community and have played a highly significant role in creating technology that is easier and more fulfilling to use. Yet, as focus in HCI is expanding to investigate complex matters of human relationships with technology over time in the intimate and contested contexts of everyday life, the notion of a ‘prototype’ may not be fully sufficient to support these kinds of inquiries. We propose the research product as an extension and evolution of the research prototype to support generative inquiries in this emerging research area. We articulate four interrelated qualities of research products—inquiry-driven, finish, fit, and independent—and draw on these qualities to describe and analyze five different yet related design research cases we have collectively conducted over the past six years. We conclude with a discussion of challenges and opportunities for crafting research products and the implications they suggest for future design-oriented HCI research

Vectorwise: Beyond Column Stores

textabstractThis paper tells the story of Vectorwise, a high-performance analytical database system, from multiple perspectives: its history from academic project to commercial product, the evolution of its technical architecture, customer reactions to the product and its future research and development roadmap. One take-away from this story is that the novelty in Vectorwise is much more than just column-storage: it boasts many query processing innovations in its vectorized execution model, and an adaptive mixed row/column data storage model with indexing support tailored to analytical workloads. Another one is that there is a long road from research prototype to commercial product, though database research continues to achieve a strong innovative influence on product development

The Development Process and The Quality of Questioning Skills Instructional Video for English Teachers at SMA Laboratorium UNDIKSHA Singaraja

The aim of this research is to identify how to develop and how is the quality of a prototype instructional video to help English teachers at SMA Laboratorium Undiksha Singaraja develop their questioning skills in teaching English. This study was a Design and Development research following ADDIE steps: Analysis, Design, Develop, Implementation and evaluation. The study showed that there were four steps to develop the prototype, they were: planning, creating prototype, prototype testing and upgrading the preliminary prototype. Also, the study suggested that the prototype was considered a good instructional video for developing questioning skills. Each evaluator completed a quantitative questionnaire and made qualitative comments. The quantitative analysis scored 98% for content, 93% for media, and 90% from users. Those numbers are categorized as very good product where it does not need any revision. Indeed, qualitative analysis gained some suggestions and comments from the experts where there are some weaknesses in the area of content and media. Though there were some revisions for the prototype, the prototype was considered as a good prototype to be finalized later as a ready-to-use product. Implication for future researcher to develop the prototype to a final product for English teachers’ professional learning is mentioned

Does consumer preference exceed initially indicated wishes? : the case of dessert topping

<p dir="LTR" align="JUSTIFY">Success of a new food product on the market is strongly related to how good that product is adapted to consumers’ preferences, wishes, expectations and needs. This paper shows the importance of consumer studies including consumer sensory tests for product prototype optimization on the case of an innovative sweet topping made from well-known Slovenian wine Teran. Empirical study was made combining two stages, first the exploratory qualitative research with focus groups and questionnaire and second a test for new food prototype with consumer sensory techniques. The results of the exploratory research were very encouraging and perceived market potential was substantial. However, when more precise and objective research techniques were applied, obtained managerial recommendation critically differ. Application of the consumer sensory tests, namely preference test and JAR (just about right) test, disconfirmed high expectations from the exploratory phase and showed that chocolate flavour is the main driver of liking the topping.</p

The Utilization of Volcanic Ash in Medium Fired Stoneware Ceramic Body

The aims of this research are to develop a medium fired stoneware body (1150oC-1250oC) as well as a prototype of glazed ceramic products based on several local clays using volcanic ash. The developed clay comes from Sukabumi, Singkawang, Bojonegoro and Malang. Research includes analysis of raw materials, development of stoneware ceramic bodies, testing of physical properties of ceramic bodies, determination of optimum ceramic bodies and development of prototype products. Raw material analysis consists of mineral analysis using XRD and Atomic Absorption Spectroscopy (AAS). Ceramic body development was carried out by the line blend method followed by testing plasticity, shrinkage, porosity and fracture strength. Prototype product development was carried out on optimum ceramic bodies composition. The results showed volcanic ash can be used to develop local clay-based ceramic stoneware bodies from Sukabumi, Bojonegoro and Malang which optimum ceramic bodies coded as Sb-2, Sb-3, Sb-4, Sb-5, Bn-5, Ml-4 and Ml-5 with volcanic ash percentage of 10%-40%. In this research, the optimum composition for Singkawang clay has not yet been found. However, opaq, matt and celadon glazes that applied to the optimum ceramic body resulted good and decent prototype product

HandyBroker - An intelligent product-brokering agent for M-commerce applications with user preference tracking

One of the potential applications for agent-based systems is m-commerce. A lot of research has been done on making such systems intelligent to personalize their services for users. In most systems, user-supplied keywords are generally used to help generate profiles for users. In this paper, an evolutionary ontology-based product-brokering agent has been designed for m-commerce applications. It uses an evaluation function to represent a user’s preference instead of the usual keyword-based profile. By using genetic algorithms, the agent tracks the user’s preferences for a particular product by tuning some parameters inside its evaluation function. A prototype called “Handy Broker” has been implemented in Java and the results obtained from our experiments looks promising for m-commerce use

Developing a Model for Teaching Speaking Skill to Students with Hearing Impairment

This research aims to: (1) learn the quality of the existing model for teaching speaking to the students with hearing impairment at SLBB YRTRW Surakarta; and (2) propose a model for teaching speaking using adjusted role play. The research method used is Research and Development. Because it is an educational research, it is classified as Educational Research and Development. This research consists of two main stages namely exploration stage and development stage. The exploration stage includes the description of the existing model and the need analysis towards an ideal model. The development stage deals with the description of the prototype, the consultation to the experts from the related field to validate the prototype, the try out of the prototype, and the feasibility of the product. In order to get the data, the researcher conducted observation, interview, FGD, and distributed questionnaire as well. The results of the research show that there are still some weaknesses of the existing instructional model for teaching speaking to the students with hearing impairment, so it is necessary to design the prototype to overcome the weaknesses. The prototype is tried out until it becomes a feasible model which is feasible for the students to learn speaking, for the teacher to teach speaking, and for developing five indicators of speaking

From X100 to Vectorwise: opportunities, challenges and things most researchers do not think about

textabstractIn 2008 a group of researchers behind the X100 database kernel created Vectorwise: a spin-o which together with the Actian corporation (previously Ingres) worked on bringing this technology to the market. Today, Vectorwise is a popular product and one of the examples of conversion of a research prototype into successful commercial software. We describe here some of the interesting aspects of the work performed by the Vectorwise development team in the process, and discuss the op- portunities and challenges resulting from the decision of integrating a prototype-quality kernel with Ingres, an established commercial product. We also discuss how requirements coming from real-life scenarios sometimes clashed with design choices and simplications often found in research projects, and how Vectorwise team addressed some of of them
