Low-cost natural interface based on head movements

Sometimes people look for freedom in the virtual world. However, not all have the possibility to interact with a computer in the same way. Nowadays, almost every job requires interaction with computerized systems, so people with physical impairments do not have the same freedom to control a mouse, a keyboard or a touchscreen. In the last years, some of the government programs to help people with reduced mobility suffered a lot with the global economic crisis and some of those programs were even cut down to reduce costs. This paper focuses on the development of a touchless human-computer interface, which allows anyone to control a computer without using a keyboard, mouse or touchscreen. By reusing Microsoft Kinect sensors from old videogames consoles, a cost-reduced, easy to use, and open-source interface was developed, allowing control of a computer using only the head, eyes or mouth movements, with the possibility of complementary sound commands. There are already available similar commercial solutions, but they are so expensive that their price tends to be a real obstacle in their purchase; on the other hand, free solutions usually do not offer the freedom that people with reduced mobility need. The present solution tries to address these drawbacks. (C) 2015 Published by Elsevier B.V

Using Transaction Utility Approach for Retail Format Decision

Transaction Utility theory was propounded by Thaler to explain that the value derived by a customer from an exchange consists of two drivers: Acquisition Utilities and Transaction utilities. Acquisition utility represents the economic gain or loss from the transaction. Where as transaction utility is associated with purchase or (sale) and represents the pleasure (or displeasure) of the financial deal per se and is a function of the difference between the selling price and the reference price. Choice of a format has been studied from several dimensions including the cost and effort as well as the non-monetary values. However, the studies that present the complete picture and combine the aspects of the tangible as well as intangible values derived out of the shopping process are limited. Most of the studies, all of them from the developed economies, have focussed on the selection of a store. They represent a scenario where formats have stabilised. However, in Indian scenario formats have been found to be influencing the choice of store as well as orientation of the shoppers. Also, retailers are experimenting with alternate format with differing success rates. The author has also not found a study that has applied this theory. It is felt that the Transactional Utility Theory may provide a suitable approach for making format decisions.

Profiling user activities with minimal traffic traces

Understanding user behavior is essential to personalize and enrich a user's online experience. While there are significant benefits to be accrued from the pursuit of personalized services based on a fine-grained behavioral analysis, care must be taken to address user privacy concerns. In this paper, we consider the use of web traces with truncated URLs - each URL is trimmed to only contain the web domain - for this purpose. While such truncation removes the fine-grained sensitive information, it also strips the data of many features that are crucial to the profiling of user activity. We show how to overcome the severe handicap of lack of crucial features for the purpose of filtering out the URLs representing a user activity from the noisy network traffic trace (including advertisement, spam, analytics, webscripts) with high accuracy. This activity profiling with truncated URLs enables the network operators to provide personalized services while mitigating privacy concerns by storing and sharing only truncated traffic traces. In order to offset the accuracy loss due to truncation, our statistical methodology leverages specialized features extracted from a group of consecutive URLs that represent a micro user action like web click, chat reply, etc., which we call bursts. These bursts, in turn, are detected by a novel algorithm which is based on our observed characteristics of the inter-arrival time of HTTP records. We present an extensive experimental evaluation on a real dataset of mobile web traces, consisting of more than 130 million records, representing the browsing activities of 10,000 users over a period of 30 days. Our results show that the proposed methodology achieves around 90% accuracy in segregating URLs representing user activities from non-representative URLs

How do fashion retail customers search on the Internet?: Exploring the use of data mining tools to enhance CRM

This paper seeks to determine the usefulness of data mining tools to SMEs in developing customer relationship management (CRM) in the fashion retail sector. Kalakota & Robinson’s (1999, p.114) model of ‘The Three Phases of CRM’ acts as a basis to explore the use of data mining software. This paper reviews the nature and type of data that is available for collection and its relevance to CRM; providing an advisory framework for practitioners for them to examine the scope and limitations of using data analysis to improve CRM. The data mining tool examined was Google Analytics (GA); an online freeware tool that enables businesses to understand how people find their site, how they navigate through it, and, ultimately, how they do or don’t become customers of it (Google Analytics, 2009). Establishing these relationships should lead to retailer development of enhanced web site aesthetics and functionality to coincide with consumer expectations. The paper finds that the competitive nature and homogeneity of the fashion retail sector requires retailers to improve the ‘reach, richness and affiliation’ (Hackney et al) of their sites by using technology to explore CRM

Unraveling the Power of Video Content and Unleashing Engagement as Multimodal Texts in Indonesia

This study intends to investigate the level of viewer engagement in co-produced video. The focus is primarily on the performance of the video content. How video engagement promotes video’s effectiveness is an issue of practices in the measurement and improvement of persuasive technology. The video content, as a multimodal text, has the power to change viewer’s attitudes and behaviors. In addition, studies noted that viewer engagement is necessary to determine the success of video content creation for specific purposes, for example, creating brand equity. Using the Video Dokumenter Pengabdian kepada Masyarakat Program Insentif Kemendikbud 2022 as a case study, Kalodikis’ model was applied to measure audience engagement. Questionnaires collected at a single point in time were used to illustrate participant’s assumptions. A cross-sectional qualitative study with interaction analysis was applied to describe video engagement metrics and how they correlated to participants’ evaluations of the video. The results highlight multiple images displayed in sequential order and show that audio reinforces the message conveyed in the visual and verbal elements of the scheme. Message framing is created through frame per second, image resolution, bit depth, and time. The obtained results indicate that there is still room for improvement. Keywords: Video content, Multimodal text, Video engagement, Viewer engagemen

Sale the seven Cs: Teaching/training aid for the (e-)retail mix

The ‘4Ps’ of the marketing mix have long been popular with students, tutors, trainers and practitioners as a learning and teaching aid. The purpose of this paper is to present an equivalent tool for retail and e-retail: ‘Sale the 7Cs’. The approach is by reference to other authors’ versions of the marketing, retail and e-retail mixes, distilled into a simplified framework: C1 Convenience; C2 Customer value and benefit; C3 Cost to the customer; C4 Computing and category management; C5 Customer franchise; C6 Customer care and service; C7 Communication and customer relationships. This simplified mnemonic is new for (e-)retail. Mini case examples are used to illustrate the applicability. These have a practical value for trainers and educators as specimen answers to activity exercises. Retailers may find the convenient 7Cs structure useful when planning strategies and tactics
