Ambient recommendations in the pop-up shop

In this paper we present the design and first-stage analysis of a purposely built, smart, pop-up wine shop. Our shop learns from visitors’ choices and recommends wine using collaborative filtering and ambient feedback displays integrated into its furniture. Our ambient recommender system was tested in a controlled laboratory environment. We report on the qualitative feedback and between subjects study, testing the influence the system had in wine choice behavior. Participants reported the system helpful, and results from our empirical analysis suggest it influenced buying behavior

Improving customer shopping experience using an Android bar-code reader application

A Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Mobile Telecommunications and Innovation (MSc. MTI)Queues continue to grow in spite of exhaustive methods done at the supermarkets to reduce it. There has been a rising interest in fast and simple shopping in supermarkets. In the ordinary shopping framework, check-out counters are distributed to minimize the queues yet at the same time it is said to be tedious. This created an exceptional opportunity that the researcher used to improve the current way of managing check-out queues and improve customer shopping experience. A review on consumer shopping behavior and existing solutions was done to get an understanding of consumer’s reaction to queues. Several theoretical models were extracted and combined in order to facilitate the study of queues and discovery of retail solutions. The literature shows that queues are an extremely complex phenomenon, and many of the drivers and pointers to customer satisfaction with queuing cannot be measured simply in terms such as the length of queue or wait time. Improving queues and satisfying customers required considerable understanding and more sophisticated responses. A mobile and web application was developed to make the management of check-out queues easier and efficient and to improve customer shopping experience. Agile methodology was adopted as the software methodology for the development of the application. Scan It, a mobile barcode scanning application was developed as a tool to offer an interactive platform where customers can scan and purchase supermarket products. It was developed for better improvement of shopping experience. The final prototype was tested to verify if the requirements were met

Interactive ubiquitous displays based on steerable projection

The ongoing miniaturization of computers and their embedding into the physical environment require new means of visual output. In the area of Ubiquitous Computing, flexible and adaptable display options are needed in order to enable the presentation of visual content in the physical environment. In this dissertation, we introduce the concepts of Display Continuum and Virtual Displays as new means of human-computer interaction. In this context, we present a realization of a Display Continuum based on steerable projection, and we describe a number of different interaction methods for manipulating this Display Continuum and the Virtual Displays placed on it.Mit zunehmender Miniaturisierung der Computer und ihrer Einbettung in der physikalischen Umgebung werden neue Arten der visuellen Ausgabe notwendig. Im Bereich des Ubiquitous Computing (Rechnerallgegenwart) werden flexible und anpassungsfähige Displays benötigt, um eine Anzeige von visuellen Inhalten unmittelbar in der physikalischen Umgebung zu ermöglichen. In dieser Dissertation führen wir das Konzept des Display-Kontinuums und der Virtuellen Displays als Instrument der Mensch-Maschine-Interaktion ein. In diesem Zusammenhang präsentieren wir eine mögliche Display-Kontinuum-Realisierung, die auf der Verwendung steuerbarer Projektion basiert, und wir beschreiben mehrere verschiedene Interaktionsmethoden, mit denen man das Display-Kontinuum und die darauf platzierten Virtuellen Displays steuern kann
