"The pen is mightier than the keyboard: Advantages of longhand over laptop note taking": Corrigendum.

Abstract: Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students’ capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers’ tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning.

Desktop PC, Tablet PC, or Smartphone? An Analysis of Use Preferences in Daily Activities for Different Technology Generations of a Worldwide Sample

Abstract: Our daily life is characterized by increasing digitalization. As a result digital technologies are becoming an integrated part of everyday activities. The most used devices are desktop PCs or laptops, tablet PCs, and smartphones, which mainly differ with regard to the screen size and the method of data entry. Given the growing diffusion of technological devices, the increasing ownership of multiple devices, and the resulting different usage patterns between devices, it is essential to gain insights into which devices are used for which activities. The aim of this analysis was to examine a total of 21 activities people engage in on a day-to-day basis with regard to desktop PC or laptop, tablet PC, and smartphone usage. When considering user characteristics with regard to technology, one of the most influential factors is the user’s age. Therefore, the sample (N = 1923) was analyzed with regard to four different technology generations. Results show that there are significant differences in device usage between the activities under study and between the four analyzed technology generations.

A System Combining Force and Vision Sensing for Automated Screw Removal on Laptops

Abstract: This brief investigates the performance of an automated robotic system, which uses a combination of vision and force sensing to remove screws from the back of laptops. This robotic system uses two webcams, one that is fixed over the robot and the other mounted on the robot, as well as a sensor-equipped (SE) screwdriver. Experimental studies were conducted to test the performance of the SE screwdriver and vision system. The parameters that were varied included the internal brightness settings on the webcams, the method in which the workspace was illuminated, and color of the laptop case. A localized light source and higher brightness setting as the laptop’s case became darker produced the best results. In this brief, the SE screwdriver was able to successfully remove 96.5% of the screws. Note to Practitioners —The amount of discarded electronic waste (e-waste) is increasing rapidly, yet efficient, nondestructive, automated methods to handle the waste have not been developed. Many e-waste products such as laptops use fasteners that need to be removed. In this brief, we focus on removing screws from laptops in a nondestructive manner in order to not damage the laptop, so its parts can be recycled. Due to the vast amounts of laptop models, it is necessary to create a method that will automatically recognize the locations of these fasteners. This brief presents a prototype robotic system that integrates force and vision sensing to automatically locate and remove screws from various models of laptops. The methodology presented in this brief is applicable to other e-waste products with a casing attached by screws. A current limitation of this brief is the robotic system that has to investigate all potential hole locations found by the vision system, although some of these locations may not correspond to valid screw locations. This brief can be extended to include a memory feature that will remember the locations of the screws for cases with similar laptops that are handled by the system to improve the processing time.

Design of an IoT smart home system

Abstract: This paper basically deals with design of an IoT Smart Home System (IoTSHS) which can provide the remote control to smart home through mobile, infrared(IR) remote control as well as with PC/Laptop. The controller used to design the IoTSHS is WiFi based microcontroller. Temperature sensor is provided to indicate the room temperature and tell the user if it's needed to turn the AC ON or OFF. The designed IoTSHS need to be interfaced through switches or relays with the items under control through the power distribution box. When a signal is sent from IoTSHS, then the switches will connect or disconnect the item under control. The designed IoT smart home system can also provide remote controlling for the people who cannot use smart phone to control their appliances Thus, the designed IoTSHS can benefits the whole parts in the society by providing advanced remote controlling for the smart home. The designed IoTSHS is controlled through remote control which uses IR and WiFi. The IoTSHS is capable to connect to WiFi and have a web browser regardless to what kind of operating system it uses, to control the appliances. No application program is needed to purchase, download, or install. In WiFi controlling, the IoTSHS will give a secured Access Point (AP) with a particular service set identifier (SSID). The user will connect the device (e.g. mobile-phone or Laptop/PC) to this SSID with providing the password and then will open the browser and go to particular fixed link. This link will open an HTML web page which will allow the user to interface between the Mobile-Phone/Laptop/PC and the appliances. In addition, the IoTSHS may connect to the home router so that the user can control the appliances with keeping connection with home router. The proposed IoTSHS was designed, programmed, fabricated and tested with excellent results.

A Study of the Z-Wave Protocol: Implementing Your Own Smart Home Gateway

Abstract: Z-Wave is one of the most popular wireless protocols for home area networks. However, there have been few studies about this protocol in recent years. Unlike Wi-Fi, Z-Wave is not an IP-compatible protocol, thus a Z-Wave device cannot directly connect to the Internet or common user devices (e.g., smartphone, laptop). The Z-Wave network uses a controller to manage and control all devices. The controller also acts as a gateway and allows a user to interact with Z-Wave devices from smartphone or laptop via the Internet or a local network. In this paper, we designed and implemented a Z-Wave gateway controller for a smart home system. We proved the feasibility of the proposed gateway using a prototype and evaluated its performance by command execution time. We also discussed the limitations of the Z-Wave protocol based on our experience.

seismo‐live: An Educational Online Library of Jupyter Notebooks for Seismology

Abstract: Efficient computer programming is becoming a central requirement in quantitative Earth science education. This applies not only to the early career stage but-due to the rapid evolution of programming paradigms-also throughout professional life. At universities, workshops, or any software training events, efficient practical programming exercises are hampered by the heterogeneity of hardware and software setups of participants. Jupyter notebooks offer an attractive solution by providing a platform-independent concept and allowing the combination of text-editing, program execution, and plotting. Here, we document a growing library with dozens of Jupyter notebooks for training in seismology. The library is made "live" through a server that allows accessing and running the notebooks in the browser on any system (PC, laptop, tablet, smartphone), provided there is internet access. The library seismo-live contains notebooks on many aspects of seismology, including data processing, computational seismology, and earthquake physics, as well as reproducible papers and graphics. It is a community effort and is intended to benefit from continuous interaction with seismologists around the world.

Users That Do Personalizing Activity Toward Their Belonging

Abstract: This research is based on the belief that “the Asian people prefer more colorful interfaces with images rather than plain interfaces” (Tzvetanova, 2007) [2]. The previous research conducted by Tzvetanova was about interface, the question is what if it’s a three dimensional form of daily use product? Will the same preferences and tendencies happen when it comes about daily use product such as laptop? There are evidences that people add stickers on their laptop, which brings up question like “what kind of users and what drives them do such activity toward their laptop?” To add/put stickers on the laptop makes it looks more literally colorful, and it also makes the laptop feels more personal. Using simple Psychographic method compared with Emotional design [1] approach, the authors made description about users who did put stickers on their laptop and dug out about what drives them did such activity. In turn this research will provides information and recommendation for the industries to be considered that there are some others crucial aspects regarding user preferences and user behavioral tendencies, rather than just technical aspect as they develop their products and massproduce it, in order to be accepted by end users.

Energy-Efficiency of Tools and Applications on Internet

Abstract: This chapter presents the comparative analysis of the various tools and applications in terms of energy-efficiency. Due to increasing demand of Green technology it is very challenging to minimize the energy consumption of software and hardware components. In addition, the use of applications or software on our computers consumes energy and it also affects the energy drain of several hardware components and system resources. Consequently, running web browsers, media players, file transfer protocols, wired and wireless security protocol applications will utilize the considerable amount of energy. In this remarkable research, we have run different types of experiments which contain the use of several measuring tools. Firstly, joulemeter and powertop (pTop) are used to monitor and calculate the energy drain of hardware and software while running web-based and stand-alone applications with Windows 7 and Linux (i.e. Ubuntu 16.04) operating systems on desktop and laptop computers. Secondly, it is presented that how much energy is consumed by an ordinary citizen on typical things of everyday use on the web.

VPad: Virtual Writing Tablet for Laptops Leveraging Acoustic Signals

Abstract: Human-computer interaction based on touch screens plays an increasing role in our daily lives. Besides smartphones and tablets, laptops are the most popular mobile devices used in both work and leisure. To satisfy requirements of many emerging applications, it becomes desirable to equip both writing and drawing functions directly on laptop screens. In this paper, we design a virtual writing tablet system, VPad, for traditional laptops without touch screens. VPad leverages two speakers and one microphone, which are available in most commodity laptops, for trajectory tracking without additional hardware. It employs acoustic signals to accurately track hand movements and recognize characters user writes in the air. Specifically, VPad emits inaudible acoustic signals from two speakers in a laptop. Then VPad applies Sliding-window Overlap Fourier Transformation technique to find Doppler frequency shift with higher resolution and accuracy in real time. Furthermore, we analyze frequency shifts and energy features of acoustic signals received by the microphone to track the trajectory of hand movements. Finally, we employ a stroke direction sequence model based on possibility estimation to recognize characters users write in the air. Our experimental results show that VPad achieves the average trajectory tracking error of only 1.55cm and the character recognition accuracy of above 90% merely through two speakers and one microphone on a laptop,

Keyboard Invariant Biometric Authentication

Abstract: Biometric authentication over internet is challenging due to the requirement of additional hardware devices to capture the required biometric data. Keystroke dynamics based approaches may be a good choice for numerous internet applications. However, keystroke data varies significantly across different types of keyboards for a given user (within user variability) which lowers the authentication accuracy, it becomes challenging to use keystroke dynamics in internet applications for authentication. In this paper, we present a unique approach for Keyboard Invariant Biometric Authentication System, which models the biometric data for one type of keyboard using the data from another type of keyboard (laptop). The experimental setup involves a desktop and a laptop computer in heterogeneous environment. Total 98 subjects have been participated in this research. We have compared the flight time of different users using desktop and laptop with the help of key pair. Regression technique is used to map the data for the two types of keyboard.

Supporting out of office software development using personal devices

Abstract: Software developers typically use multiple large screens in their office setup. However, they often work away from the office where such a setup is not available, instead only working with a laptop computer and drastically reduced screen real estate. We explore how developers can be better supported in ad-hoc scenarios, for example when they work in a cafe, an airport, or at a client's site. We present insights into current work practices and challenges when working away from the usual office desk sourced from a survey of professional software developers. Based on these insights, we introduce an IDE that makes use of additional personal devices, such as a phone or a tablet. Parts of the IDE can be offloaded to these mobile devices, for example the application that is being developed, a debugging console or navigational elements. A qualitative evaluation with professional software developers showed that they appreciate the increased screen real estate.

Managing Devices of a One-to-One Computing Educational Program Using an IoT Infrastructure.

Abstract: Plan Ceibal is the name coined in Uruguay for the local implementation of the One Laptop Per Child (OLPC) initiative. Plan Ceibal distributes laptops and tablets to students and teachers, and also deploys a nationwide wireless network to provide Internet access to these devices, provides video conference facilities, and develops educational applications. Given the scale of the program, management in general, and specifically device management, is a very challenging task. Device maintenance and replacement is a particularly important process; users trigger such kind of replacement processes and usually imply several days without the device. Early detection of fault conditions in the most stressed hardware parts (e.g., batteries) would permit to prompt defensive replacement, contributing to reduce downtime, and improving the user experience. Seeking for better, preventive and scalable device management, in this paper we present a prototype of a Mobile Device Management (MDM) module for Plan Ceibal, developed over an IoT infrastructure, showing the results of a controlled experiment over a sample of the devices. The prototype is deployed over a public IoT infrastructure to speed up the development process, avoiding, in this phase, the need for local infrastructure and maintenance, while enforcing scalability and security requirements. The presented data analysis was implemented off-line and represents a sample of possible metrics which could be used to implement preventive management in a real deployment.

Ergonomic Student Laptop Desk Design Using the TRIZ Method

Abstract: Students are among the most common users of laptop devices. With the variety of activities done by students using their laptops, many issues are faced because the physical interaction between user and laptop is not well designed. This research aims to produce a laptop desk design for students. The study was conducted with 30 undergraduate and postgraduate student subjects in an integrated campus environment of Universitas Islam Indonesia. Based on the results of questionnaires given to the subjects, six main problems of the laptop desks were identified: storage, lack of additional functions, lack of laptop mats, complaints while typing or using laptops, and complaints of neck pain. An analysis was done to find a solution using the TRIZ method. The TRIZ analysis tools used were cause and effect chain analysis (CECA) and engineering contradiction. The validation of the success of the solution was determined by using a homogeneity test with P > 0.05. This shows that there is no difference between the solutions given to the table design in terms of consumer expectation.

An Indoor Mobile Scanning System with Multi-Controller

Abstract: Scanning an indoor environment has become a necessity in the various field of applications in Architecture, Engineering, Construction (AEC) area. However, most of the available scanning systems are stationary, hence making the process of data collection more difficult, especially when dealing with the larger indoor area. Therefore, a mobile scanning system is developed here to handle the above issue. This paper will highlight the process of designing and developing the system. It has been adequately developed, where the design and suitable components were considered in order to make it able to carry a laptop which acts as the communicator with the suitable sensor that will scan the surroundings and a host personal computer (PC). Kinect sensor is used due to its advantages regarding workability and cost. The system is also equipped with an Android-based controller, connected to the platform via Bluetooth, which can be used to manoeuvre the mobile scanner using either auditory/voice or an arrow pad. Based on several experiments and testing conducted, the system can scan and display its surroundings in the 2D image and depth data. These are important in developing a suitable model representing the scanning area in the future. Both auditory and arrow pad controller is also working, where, by utilising an Android-based platform as the controller, the system is having the advantages of more freedom and beneficial compared to the existing mobile system without a similar controller.

sMouse : A Development of the Analog Operability of Computer Mouse

Abstract: Computer mouse have become necessary devices to use computers. There are many people who use external mice as the interfaces even today when it is common to carry laptop computers. It means that "Analog operability", to move a Mouse with hands, is suitable for a human being. However, today, a small laptop has various functions. In addition, the data is stored in the cloud service. From those reasons, to carry an external device is not suitable to today's lifestyle. Thereupon, we propose an application to turn smartphones as external mice. The goal is not the concept of IoT (Internet of Things), which suggests that various things should be connected to the Internet and be digitalized, but the concept that implement the analog tool or operability into the digital device or environment. Digital tools or environments have serious problems that those are stolen or copied easily. If the appearance or the operability is fundamentally unique, the similarity is quite obvious, and possibilities of being copied are low. Our aim is not only space saving of the mobile office, but also the attempt based on the idea of "design, which cannot be copied".

Power companion status

Abstract: Battery status information may be provided to an information handling system, such as a laptop computer, through the same cable as the power. The transfer of battery status information may be facilitated by a power delivery (PD) controller in the external battery that communicates with a power delivery (PD) controller in the laptop computer. One cable type that can support the transfer of battery status information is a Universal Serial Bus (USB) Type-C cable. Battery status information may be transferred as packetized data according to a vendor-defined messaging (VDM) protocol from the external battery to the laptop computer. An embedded controller within the laptop computer may decode the packets and report the battery status information to components within the laptop computer. The battery status may be accessed through application programming interfaces (APIs) by third-party applications or displayed through the operating system.
