Photo Sharing

Today, image gallery applications on mobile devices tend to be stand-alone and offline. For people who want to share photos with others, many add-on tools have been developed to connect the gallery applications to Internet services to enable photo-sharing. The authors argue that photocentric social interaction is best supported when the gallery application is fully integrated with an Internet service. In this case, no additional tools are needed and the user’s image content is fully synchronized with the service. They designed and implemented a service-integrated mobile gallery application with a corresponding Internet service. Moreover, they conducted a field study with 10 participants to compare our application with a state-of-the-art gallery application combined with an add-on photo-sharing tool. Their application was preferred by most participants and it was especially appreciated because of the user experience. Above all, the results show that social activity increased amongst the participants while using our application.

The author argues that photo-centric social interaction is best supported when the gallery application is fully integrated with an Internet service. In this case, no additional tools are needed and the user’s image content is fully synchronized with the service. To research the topic, Image Exchange, a service-integrated mobile gallery application with a corresponding Internet service, was designed and implemented. Moreover, a field study was conducted with 10 participants to compare Image Exchange with a state-of-the-art gallery application combined with an add-on photo sharing tool. Image Exchange was preferred by most participants and it was especially appreciated because of the user experience.

This case is used in Darden’s “Digital Marketing” course elective. It explores the experience of a niche search firm whose founder attributed her ability to open her recruiting firm to LinkedIn and the new model of recruiting it created. LinkedIn Corporation had been one of the most successful companies in the digital media space, with more than 4,000 employees and a market capitalization of over $25.5 billion in August 2013. But few people knew how LinkedIn had grown and how it had become profitable. LinkedIn had multiple unique aspects to explore: its focus on professional--not simply personal--social interaction, the company’s B2B components, and also its marketing positioning from user experience to targeting and growth strategy.

Many mobile devices embed nowadays inertial sensors. This enables new forms of human-computer interaction through the use of gestures (movements performed with the mobile device) as a way of communication. This paper presents an accelerometer-based gesture recognition system for mobile devices which is able to recognize a collection of 10 different hand gestures. The system was conceived to be light and to operate in a user-independent manner in real time. The recognition system was implemented in a smart phone and evaluated through a collection of user tests, which showed a recognition accuracy similar to other state-of-the art techniques and a lower computational complexity. The system was also used to build a human-robot interface that enables controlling a wheeled robot with the gestures made with the mobile phone

Large neural networks are difficult to deploy on mobile devices because of intensive computation and storage. To alleviate it, we study ternarization, a balance between efficiency and accuracy that quantizes both weights and activations into ternary values. In previous ternarized neural networks, a hard threshold Δ is introduced to determine quantization intervals. Although the selection of Δ greatly affects the training results, previous works estimate Δ via an approximation or treat it as a hyper-parameter, which is suboptimal. In this paper, we present the Soft Threshold Ternary Networks (STTN), which enables the model to automatically determine quantization intervals instead of depending on a hard threshold. Concretely, we replace the original ternary kernel with the addition of two binary kernels at training time, where ternary values are determined by the combination of two corresponding binary values. At inference time, we add up the two binary kernels to obtain a single ternary kernel. Our method dramatically outperforms current state-of-the-arts, lowering the performance gap between full-precision networks and extreme low bit networks. Experiments on ImageNet with AlexNet (Top-1 55.6%), ResNet-18 (Top-1 66.2%) achieves new state-of-the-art.

In this paper we introduce SNF, a framework that synthesizes (S) network function (NF) service chains by eliminating redundant I/O and repeated elements, while consolidating stateful cross layer packet operations across the chain. SNF uses graph composition and set theory to determine traffic classes handled by a service chain composed of multiple elements. It then synthesizes each traffic class using a minimal set of new elements that apply single-read-single-write and early-discard operations. Our SNF prototype takes a baseline state-of-the-art network functions virtualization (NFV) framework to the level of performance required for practical NFV service deployments. Software-based SNF realizes long (up to 10 NFs) and stateful service chains that achieve line-rate 40 Gbps throughput (up to 8.5x greater than the baseline NFV framework). Hardware-assisted SNF, using a commodity OpenFlow switch, shows that our approach scales at 40 Gbps for Internet Service Provider-level NFV deployments.

Traditional Approaches

With the recent advances in cloud computing and the capabilities of mobile devices, the state-of-the-art of mobile computing is at an inflection point, where compute-intensive applications can now run on today's mobile devices with limited computational capabilities. This is achieved by using the communications capabilities of mobile devices to establish high-speed connections to vast computational resources located in the cloud. While the execution scheme based on this mobile-cloud collaboration opens the door to many applications that can tolerate response times on the order of seconds and minutes, it proves to be an inadequate platform for running applications demanding real-time response within a fraction of a second. In this chapter, the authors describe the state-of-the-art in mobile-cloud computing as well as the challenges faced by traditional approaches in terms of their latency and energy efficiency. They also introduce the use of cloudlets as an approach for extending the utility of mobile-cloud computing by providing compute and storage resources accessible at the edge of the network, both for end processing of applications as well as for managing the distribution of applications to other distributed compute resources.

The Future

The Internet is growing ever more mobile – meaning, that an ever greater proportion of Internet devices are mobile devices. This trend necessitates new designs and will produce new and even unpredictable conceptions about the very nature of the Internet and, more fundamentally, the nature of social interaction. The engineering response to growing mobility and complexity is difficult to predict. This chapter summarizes the past and the present ways of dealing with mobility, and uses that as context for trying to understand what needs to be done for the future. Central to the conception of future mobility is the notion of “always available” and highly interactive applications. Part of providing acceptable service in that conception of the mobile Internet will require better ways to manage handovers as the device moves around the Internet, and ways to better either hide or make available a person's identity depending on who is asking.
