Keyboard with tactile feedback on smartphone touch screen
No full textPressing buttons on a smartphone touch screen is difficult if you are not looking at the screen. We developed a numerical keyboard that provides a tactile feedback using phone short vibrations. The feedback is provided both when the user swipes the keyboard and when he presses keys. We describe how we implemented it on iPhone7, using the iPhone 3Dtouch capability and the UIFeedbackGenerator
A framework to enhance the user experience of car mobile applications
No full textWe describe the rationale, the design and development of an iOS framework to enhance the end user experience of car-related apps. The car framework fuses the smartphone sensors' raw data to detect user behaviour and car events, and provides relevant and timely information that an app can use to relief the user from manually inputting data and to foster implicit interaction. Thus, app developers can focus on user needs and UX rather than on code complexity. We show how detected events map common needs of car-related apps
Communication control and driving assistance to a platoon of vehicles in heavy traffic and scarce visibility
No full textAdecentralized communication and control system is
presented for driving assistance and automation along designated
highway segments. This paper is based on a hybrid dynamical
model describing vehicular motion, and the structure of a safe
controller is presented. A ranging and communication system
provides information for a vehicle and its nearest neighbors. The
system is capable of handling sudden changes of regime, overtakes,
reentries, as well as a number of maneuvers dictated by safety
requirements under partially unpredicted events. A user-friendly
interface, based on a palmtop computer, is developed to assist
drivers visually and acousticall
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
«At the risk of entering into minute and very uninteresting particulars...»: la querelle tra Antonio Panizzi e Nicholas Harris Nicolas
Full text linkThe paper analyzes the dispute between Panizzi and Nicolas regarding the innovations proposed by the Italian librarian at the British Museum library. The innovations introduced by Panizzi mainly concern the management of the reading room and the rules for the new printed catalog of the printed books ofthe British Museum library.L’articolo analizza la disputa fra Panizzi e Nicolas in merito alle innovazioni proposte dal bibliotecario italiano alla biblioteca del British Museum. Le innovazioni introdotte da Panizzi riguardano principalmente la gestionedella sala di lettura e le regole per il nuovo catalogo a stampa dei libri a stampa della biblioteca del British Museum
Capturing and using context in a mobile annotation application
No full textWe present an approach to integrating extemporary annotations on topics of interest to a user with information on the context in which the annotation is being taken. Context is here defined in terms of the set of surrounding devices (Bluetooth Low Energy enabled smartphones, WiFi hotspots) and the current calendar event. Contextify is a context-aware Android application which detects the current context and organizes the notes taken within context, allowing a form of context-based retrieval. Thus, the detected context represents location, other people present (referring to their BLE equipped smartphones as user proxies), and events. Users can easily retrieve notes when they return to the context where they created them. A context similarity algorithm derived from the Jaro-Winkler string similarity algorithm is used to compare contexts. Each note is tagged by the user and the system suggests the most appropriate tag, among the already used ones, at annotation creation time: the suggestion is based on the similarity of the current context with the contexts associated with previously tagged notes
Enhancing Interface Design with AI: An Exploratory Study on a ChatGPT-4-Based Tool for Cognitive Walkthrough Inspired Evaluations
No full textThis paper introduces CWGPT, a ChatGPT-4-based tool designed for Cognitive Walkthrough (CW) inspired evaluations of web interfaces. The primary goal is to assist users, particularly students and inexperienced designers, in evaluating web interfaces. Our tool, operating as a conversational agent, provides detailed evaluations of a user-specified task by intelligently guessing the subtasks and actions required to accomplish them, answering the standard CW questions, and providing helpful feedback and practical suggestions to improve the usability of the analyzed interface. For our study, we selected a group of web applications designed by students from a Web and Software Architecture course. We compare the outcome of the CWs we executed on ten web apps against the corresponding CWGPT analyses. We then describe the study we conducted involving five author-students to assess the tool's efficacy in helping them recognize and solve usability issues. In addition to introducing a novel adaptation of ChatGPT, the outcomes of the described experience underscore the promising potential of AI in usability evaluations
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
