Natural user interfaces are becoming popular. One of the most common natural nowadays voice activated interfaces, particularly smart personal assistants such as Google Assistant, Alexa, Cortana, and Siri. This paper presents results an evaluation these four in two dimensions: correctness their answers how responses feel to users. Ninety-two participants conducted evaluation. Results show that Alexa Assistant significantly better than Siri Cortana. However, there is no statistically...

Standardized questionnaires are one of the methods used to evaluate User Experience (UX). composed an invariable group questions that users answer themselves after using a product or system. They considered reliable and economical apply. The standardized most recognized for UX evaluation AttrakDiff, UEQ, meCUE. Although structure, format, content each known in detail, there is no systematic literature review (SLR) categorizes uses these primary studies. This SLR presents eligibility protocol...

Background. Standardized questionnaires are well-known, reliable, and inexpensive instruments to evaluate user experience (UX). Although the structure, content, application procedure of three most recognized (AttrakDiff, UEQ, meCUE) known, there is no systematic literature review (SLR) that classifies how these have been used in primary studies reported academically. This SLR seeks answer five research questions (RQs), starting with identifying uses each questionnaire over years by...

This paper describes a project-based learning (PBL) experience in compilers course. In PBL, students play an active goal and professors act like facilitators of knowledge. face authentic motivating problems that require them to answer complex questions develop success skills. We first explain why the majority projects used course are not fit for this teaching strategy. Based on problem, we propose project enables student motivation sustained inquiry. describe one-semester with two 40...

Maintaining high cognitive activity is vital for the mental health of seniors. Taking part in leisure activities an exciting and gratifying way to accomplish this, with video games having several advantages this use. The present study a work progress develop different digital natural voice interfaces that can be easily pleasantly used by older adults stimulate their needs. A Wizard Oz two was developed evaluate user experience perceived when using such applications. Positive results enhance...

Motion tracking is a critical task in many computer vision applications. Existing motion techniques require either great amount of knowledge on the target object or specific hardware. These requirements discourage wide spread commercial applications based tracking. In this paper, we present novel three degrees freedom system that needs no and only requires single low-budget camera can be found installed most computers smartphones. Our estimates, real time, three-dimensional position...

ModelCC is a model-based parser generator. Model-based generators decouple language specification from processing. This model-driven approach avoids the limitations imposed by whose specifications must conform to specific grammar constraints. Moreover, supports reference resolution within specification. Therefore, it does not parse just trees but can also efficiently deal with abstract syntax graphs. These graphs even include cycles (i.e. they are constrained directed acyclic graphs).

One goal of network providers is to allow their customers establish end-to-end circuits as efficiently possible. A novel way tackle this problem use function virtualization (NFV). Indeed, NFV enables expose a virtual topology so that can compute an path for data. With the advent software-defined networking (SDN), challenge updating forwarding rules automatically achieve has been largely addressed. However, design and standardization northbound interface between provider customer are still in...

This paper proposes the creation of a smart meeting room through incorporation PIR sensor and an AWS IoT button that allows booking system to reflect more precise availability rooms according actual occupancy status. The Internet Things (IoT) devices are controlled using Wi-Fi module them connect REST web service integrate with open source Meeting Room Booking System (MRBS). In order evaluate storyboard evaluation was conducted 47 participants. All participants filled out User Experience...
