The $3 recognizer: simple 3D gesture recognition on mobile devices

Abstract: We present the $3 Gesture Recognizer, a simple but robust gesture recognition system for input devices featuring 3D acceleration sensors. The algorithm is designed to be implemented quickly in prototyping environments, is intended to be device-independent and does not require any special toolkits or frameworks, but relies solely on simple trigonometric and geometric calculations. Our method requires significantly less training data than other gesture recognizers and is thus suited to be deployed and to deliver results rapidly.

Mobile object locating device with GPS-receiver e.g. for finding position of vehicles, including automobiles and motorcycles, and items of luggage, has device for computing the direction and distance of user to current position of object

Abstract: Position finding device includes a GPS-receiver for determining the current position of the object being located and of the user, an antenna for the GPS-receiver (40), a device for computing the direction and/or distance of the user to the current position of the object (stored in memory) and a device (7,8,10) for acoustic, optical and/or sensor-motor output especially of the direction and/or distance

SmartDiet: offloading popular apps to save energy

Abstract: Offloading computation to cloud has been widely used for extending battery life of mobile devices. However, little effort has been invested in applying the offloading techniques to communication-related tasks. We propose SmartDiet, a toolkit to identify the constraints that reduce offloading opportunities and to calculate the energy-saving potential of offloading communication-related tasks. SmartDiet traces the method-level application execution and estimates the allocation of communication energy cost from traffic traces. We discuss key features of SmartDiet and show some preliminary results using a prototype implementation.

A5G Architecture for the Factory of the Future

Abstract: Factory automation and production are currently undergoing massive changes, and 5G is considered being a key enabler. In this paper, we state uses cases for using 5G in the factory of the future, which are motivated by actual needs of the industry partners of the “5Gang” consortium. Based on these use cases and the ones by 3GPP, a 5G system architecture for the factory of the future is proposed. It is set in relation to existing architectural frameworks.

DNS-Based Solution for Operator Control of Selected IP Traffic Offload

Abstract: In this paper, we consider the Selected IP Traffic Offload (SIPTO) approach to handle increased data traffic of both local and macro-cellular networks. We devise different ap- proaches based on operator defined offload policies on a per des- tination domain name basis, which offer operators fine-grained control of whether a new IP connection should be offloaded or provided via the core network. Two of our solutions are based on Network Address Translation (NAT) named simple-NATing and twice-NATing, while a third one employs simple tunneling. These solutions support all kinds of UEs including those that support a single Packet Data Protocol (PDP) context/Packet Data Network (PDN) connection. In a forth solution, we consider the case where a User Equipment (UE) supports multiple PDP contexts/PDN connections, with at least one dedicated for SIPTO traffic. A qualitative analysis and a simulation study are presented.
