Problems with Using Smart Devices for Business and Efforts to Resolve Them Problems with Using Smart Devices for Business and Efforts to Resolve Them Shinji Takahara Masatomo Yasaki In the current consumer market, new means of communication are rapidly becoming preva- lent. They include smart devices such as smartphones and tablets, applications that operate on those smart devices, and high-speed wireless communications such as Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX). To address this trend, corporate users have started considering the possibility of increasing their sales and improv- ing their business efficiency by making active use of smart devices in their business. However, challenges associated with introducing these devices have been revealed as well, such as con- cerns about security and the streamlined connection of such devices with existing systems. In this paper, we describe services that enable these devices to be used in the optimal way (mobile sales operation support service) in sites where sales take place. We also cover a method for vertical integration when introducing devices, networks, service platforms and ser- vices, as an approach to introducing this system into companies. 1. Introduction communication and applications for smart devices In the Japanese market, the iPhone was launched (hereafter “applications”) to improve their business in 2008, the first device running Android in 2009, efficiency. and the iPad in 2010.

    Paper—Defining Stable Touch Area based on a Large-Screen Smart Device in 3D-Touch Interface Defining Stable Touch Area based on a Large-Screen Smart Device in 3D-Touch Interface https://doi.org/10.3991/ijim.v13i02.10153 YounghoonSeo, Dongryeol Shin, Choonsung Nam * Sungkyunkwan University, Suwon, Republic of Korea( ) [email protected] Abstract—Touch interface technologies for mobile devices are essentially in use. The purpose of such touch interfaces is to run an application by touching a screen with a user’s finger or to implement various functions on the device. When the user has an attempt to use the touch interface, users tend to grab the mobile device with one hand. Because of the existence of untouchable areas to which the user cannot reach with the user’s fingers, it is possible to occur for a case where the user is not able to touch a specific area on the screen accurately. This results in some issues that the mobile device does not carry out the user’s desired function and the execution time is delayed due to the wrong implemen- tation. Therefore, there is a need to distinguish the area where the user can sta- bly input the touch interface from the area where the users cannot and to over- come the problems of the unstable touch area. Furthermore, when the size of the screen increases, these issues will become more serious because of an increase in the unstable touch areas. Especially, an interface that receives position and force data like 3D-touch requires the stable area setting different from the con- ventional 2D-touch.

X, NO. X, MONTH YEAR 1 Identification of Wearable Devices with Bluetooth Hidayet Aksu, A. Selcuk Uluagac, Senior Member, IEEE, and Elizabeth S. Bentley Abstract With wearable devices such as smartwatches on the rise in the consumer electronics market, securing these wearables is vital. However, the current security mechanisms only focus on validating the user not the device itself. Indeed, wearables can be (1) unauthorized wearable devices with correct credentials accessing valuable systems and networks, (2) passive insiders or outsider wearable devices, or (3) information-leaking wearables devices. Fingerprinting via machine learning can provide necessary cyber threat intelligence to address all these cyber attacks. In this work, we introduce a wearable fingerprinting technique focusing on Bluetooth classic protocol, which is a common protocol used by the wearables and other IoT devices. Specifically, we propose a non-intrusive wearable device identification framework which utilizes 20 different Machine Learning (ML) algorithms in the training phase of the classification process and selects the best performing algorithm for the testing phase.

  • The Mobile Operating Systems Analysis 2012- 2017: Who Wins: Android Vs
    The Mobile Operating Systems Analysis 2012- 2017: Who wins: Android vs. iOS vs. Windows? 4.4.5 Middle East and Africa Mobile OS Sales Forecast 2012-2017 Dominated by the Symbian platform in 2012, visiongain believes that Android will pick up where the incumbent leaves off. Smart device sales in the MEA region will inevitably be driven by low- cost Android handsets from OEMs such as Huawei, ZTE, HTC, and Motorola. Windows and iOS will have a more pronounced impact on the Middle Eastern market than the African one, with higher sales volumes in countries such as Israel, the UAE, Bahrain, and Saudi Arabia. Visiongain forecasts this region to have relatively low smart device penetration in 2017, reaching sales of just over 107 million units that year. See Figure 4.31 and Table 4.25.
