We consider an inter-layer FEC technique combined with hierarchical 16QAM schemes for stereoscopic video transmission over AWGN relay channels. The proposed system with the suitable hierarchical value (α) can gain about 2.26–6.18 dB in the average PSNR performance, compared with the system using conventional FEC and hierarchical 16QAM schemes.
The supervision of rehabilitation exercises is crucial for a successful therapy. Due to a lack of therapists, technical assistance systems have recently come into focus to assist patients during their exercises. Latest research proved that characteristic motion errors can be detected by using the Kinect skeleton joints in connection with Incremental Dynamic Time Warping (IDTW) and machine learning...
This work proposes an approach for performing Human-Robot Cooperation (HRC) tasks by integrating a Brain Computer Interface (BCI) with a robotic manipulator. In detail, the user can select one among six different objects via BCI, which analyzes the P300 signals generated by the brain when the images of the selectable objects appear on the screen. Then, the selected object is recognized by a Support...
We propose a bio-information inference platform, which can be used for inferring important bio-information based on the machine learning using biomedical signals collected from underwear-type wearable devices. This platform has been consisted of an underwear-type wearable device, a smartphone, a server, and a doctor terminal. Using this platform, we can collect biomedical signals during 24 hours securely...
In this paper we present a scalable multi-view video streaming system with client-side view interpolation. Most parts of the system have been shown to be able to perform in real-time, but never as a complete system. Even though our algorithms are not yet highly optimized, we show that running a complete multi-view streaming system video on consumer hardware is possible today. Since multi-view coding...
Improper sitting posture can lead to a number of serious health disorders connected to the musculoskeletal system. Especially nowadays sitting periods at work or at home are increasing, and therefore consistent stance monitoring can help users improve their sitting habits and avoid related complications. In this work, we present SPoMo a real-time, practical, wearable system that automatically tracks...
This study describes an User-Centered approach to design an User Interface (UI) to support daily activities of people with dementia. Such interface is the main hub of a home automation system able to monitor the house and reminds to the users some information when they approach the door to leave the home. In order to involve end users in UI evaluation at the end of the first stage of the design process,...
In this paper, we implement a voice command interface for smart home automation systems. The proposed interface defines command patterns, which can be easily mapped to specific devices, device functionalities and device locations. Also, the control of devices in a group is supported. The proposed voice command interface is implemented in way that supports various voice recognition engines.
As part of the voice command system for the existing smart home automation solution, we want to build the wake word module. This module should continuously listen and process the sounds from the environment, in order to detect the pre-defined wake word. Once the wake word is pronounced by the user, wake word module should trigger the actual voice command processing, which will result in the action...
This paper examines the 4kUHD video quality from streaming over an IEEE 802.11ac wireless channel, given measured levels of packet loss. Findings suggest that there is a strong content dependency to loss impact upon video quality but that, for short-range transmission, the quality is acceptable, making 4kUHD feasible on head-mounted displays.
Wireless sensors networks have an enormous potential for measuring environmental parameters such as those found in building or residential scenarios. The range of available sensors is not only limited temperature, gas, humidity or presence detection, but even power grid analyser can be integrated. This work aims to develop a Home energy management system for a residential scenario or nanogrid. Inside...
The digitalization of modern television broadcasts makes it possible to provide interactive content to consumers over the air. But the hitherto unsecured nature of such broadcasts combined with the ever-increasing complexity of Smart TV software have created an opportunity for attackers to strike at consumers. DVB has updated the relevant standard to allow broadcasters to secure their services against...
Autonomous driving is the next breakthrough in automotive industry. Although the current achievements are very promising we still envision applications in which a certain level of assistance from the remote operator would be required. The goal of the project is to realize a semi-autonomous driving platform prototype with low-latency control/command channel to the operator over the 5G wireless network...
Hybrid Broadcast Broadband TV (HbbTV) is an industry standard for hybrid multimedia devices that are able to combine broadcast and IPTV delivery. This paper deals with companion screen devices, companion screen applications and communication of those applications with HbbTV terminal and its applications. Companion screen devices offer additional content to user and for pleasant experience communication...
This paper describes a flexible multimedia stack which provides media content from number of different streaming protocols. The main goal is to facilitate and accelerate integration with different TV and Set Top Box platforms. Presented solution can be used on Android as well as on Linux based systems. Advantages of this solution are unified data flow and processing of media data. It provides elementary...
In this paper, an analytical model for assigning tasks to the actors is presented. The model is based on queuing networks and tries to minimize the network make-span in wireless sensor and actor networks. To achieve this goal, through a steady state analysis of the proposed model to solve equations and inequalities, the best distribution rates of tasks to the actors are calculated. It is shown that...
A 37–40 GHz power amplifier (PA) has been designed and fabricated on 0.1-μm GaAs pHEMT process. Utilizing two-way direct shunt power combining and low impedance transmission line pre-matching technique, the PA achieves measured saturation output power of 25.6 dBm with peak power added efficiency (PAE) of 28% at 38 GHz. The measured output 1-dB gain compression point is 24.6 dBm and the peak gain is...
