    Bio-sensing wearables are currently advancing to provide users with a lot of information about their physiological and affective states. However, relatively little is known about users' interest in acquiring, sharing and receiving this information and through which channels and modalities. To close this gap, we report on the results of an online survey (N=109) exploring principle aspects of the design space of wearables such as data types, contexts, feedback modalities and sharing behaviors. Results show that users are interested in obtaining physiological, emotional and cognitive data through modalities beyond traditional touchscreen output. Valence of the information, whether positive or negative affects the sharing behaviors

    Föreliggande examensarbete undersöker möjligheterna att effektivisera order- och lagerhanteringen av surfplattor hos företaget Företag A. Arbetet Ă€r avgrĂ€nsat till företagets varuhus i Barkarby och till de tvĂ„ största mĂ€rkena pĂ„ marknaden just nu; Apple och Samsung. Detta Ă€r ett Ă€mne som Ă€r relativt nytt eftersom det Ă€r en relativt ny marknad runt hela vĂ€rlden som har exploderat sedan Apples första lansering av surfplattan. Eftersom Företag A sĂ€ljer samtliga mĂ€rkens surfplattor vilka har helt olika efterfrĂ„gan, sĂ„ kan deras order- och lagerhantering bli svĂ„rhanterlig. De uppstĂ€llda frĂ„gestĂ€llningarna som ligger till grund för arbetet Ă€r: Vilken/vilka teoretiska modeller om orderhantering kan bĂ€st tillĂ€mpas pĂ„ fallet Företag A Barkarby? Vilka Ă„tgĂ€rder skulle kunna genomföras för att effektivisera det nuvarande arbetssĂ€ttet? UtifrĂ„n dessa frĂ„gor har en del modeller undersöks huruvida de passar in i bĂ„de teori och praktik pĂ„ Företag As sĂ€tt att hantera de mest sĂ„lda surfplattorna pĂ„ sitt lager. Genom att studera deras arbetssĂ€tt nĂ€r det gĂ€ller ordrar och förvaring pĂ„ lagret kan sedan passande modeller appliceras. Fallstudien har till stor del genomförts genom att utifrĂ„n studielitteratur diskutera Ă€mnet med personal frĂ„n Företag A; bĂ„de frĂ„n huvudkontoret och frĂ„n Barkarbyvaruhuset.Resultatet frĂ„n uppsatsen Ă€r att det inte finns nĂ„gon befintlig modell som passar in till 100% pĂ„ Företag As arbetssĂ€tt, dĂ€remot finns det andra faktorer som kan Ă€ndras pĂ„ för att fĂ„ en mer kontinuerlig och överseende orderhantering. Marknaden för surfplattor Ă€r otroligt oförutsĂ€gbar och fluktuerar ofta utan nĂ„got utstuderat mönster. Det enda som har visat sig vara sĂ€kert Ă€r Ă„tgĂ„ngen av de tvĂ„ mest populĂ€ra mĂ€rkena nĂ€r de slĂ€pper en ny modell.Marknaden för elektronikkedjor Ă€r otroligt konkurrensstyrd, inte bara i Sverige utan i hela Europa, vilket gör det Ă€n viktigare att ha rĂ€tt kvantitet pĂ„ lager. Finns inte det kunderna vill ha sĂ„ gĂ„r de nĂ„gon annanstans, eftersom priserna pĂ„ surfplattor Ă€r densamma överallt.This paper examines the possibilities to make the handling of orders and storage for tablets more efficient for Företag As warehouse in Barkarby. The work is limited to the company’s warehouse in Barkarby and to the two largest manufacturers for tablets; Apple and Samsung. This is a relatively new subject because it is a relatively new market around the world, which has exploded since Apple released their first tablet. Because Företag A sells every manufacturer’s tablet, all with different demands, it makes the organisation of orders and storage quite difficult.The formulated questions which this paper is based on are: Which of the theoretical models about orderhandeling can best be applied on the case of Företag A Barkarby? What measures can be used to make the current way of working more efficient? With these questions as a starting point some models have been studied whether they fit in theory and practice in the way Företag A works when it comes to handling the most sold tablets in their storage. Through studying their way of working suiting models can be applied. The case study has mainly been implemented by after reading student literature discussing the problems with people who works at Företag A; both at the head quarters and in the warehouse in Barkarby.The result from this essay is that there isn’t any model which fits 100 % on Företag A’s way of work, but there are other factors that can be changed to get a more continuous and overseeing order process. The market for tablets is very unpredictable and fluctuates often without a worked out pattern. The only sure thing is the demand with the two most popular manufacturers when they release a new model.The market for electronic chains is extremely competition controlled, not only in Sweden but in all of Europe, which makes it even more important to have the right quantity in storage. If the product that the customers want isn’t available they simply go somewhere else, since the prices are the same everywhere

    Wearable Communications in 5G: Challenges and Enabling Technologies

    As wearable devices become more ingrained in our daily lives, traditional communication networks primarily designed for human being-oriented applications are facing tremendous challenges. The upcoming 5G wireless system aims to support unprecedented high capacity, low latency, and massive connectivity. In this article, we evaluate key challenges in wearable communications. A cloud/edge communication architecture that integrates the cloud radio access network, software defined network, device to device communications, and cloud/edge technologies is presented. Computation offloading enabled by this multi-layer communications architecture can offload computation-excessive and latency-stringent applications to nearby devices through device to device communications or to nearby edge nodes through cellular or other wireless technologies. Critical issues faced by wearable communications such as short battery life, limited computing capability, and stringent latency can be greatly alleviated by this cloud/edge architecture. Together with the presented architecture, current transmission and networking technologies, including non-orthogonal multiple access, mobile edge computing, and energy harvesting, can greatly enhance the performance of wearable communication in terms of spectral efficiency, energy efficiency, latency, and connectivity.Comment: This work has been accepted by IEEE Vehicular Technology Magazin
