Real estates and housing associations have to incorporate modern mobile and internet technologies in their service offerings to stay attractive for clients. While doing so, they must take into account the special needs of their target audience. The elderly is an increasing target group which refuses modern consumer electronics with overwhelming features. Therefore, easy-to-use interaction models based...
In this paper, a light-weight 3D object reconstruction system is proposed. It aims to fulfill the increasing demand for fast and reliable 3D reconstruction in a mobile environment. Thereby, people can directly use their own device (e.g. mobile phone or tablet) to reconstruct desired objects into 3D models. The system is implemented and tested on an embedded board, MIO-5250, that is equipped with the...
In this paper, we design a new mobile traffic warning triangle (MTWT) which consist five parts: distance measurement unit, reflective tracking function, LED indicate, emergency calling and embedded controller. The MTWT can track the white line in road side then move a fix distance and rise the LED indicate triangle. It also can detect the distance between two cars and alarm the driver. The GPS module...
Hybridcast is a new service that integrates broadcast services and broadband communication services. This service has already launched in Japan. In this paper, we describe overall system of Hybridcast service, especially the mobile device coordinated system and the application of the system. The number of Hybridcast content is gradually increasing. For the further spread of Hybridcast content, we...
There is a demand for a way for blind persons to receive information at any time and in any place. This is impossible to realize with existing user interfaces using voice output, so this paper introduces the world's first a wristwatch-style refreshable braille display. This braille display has 8 braille cells and 16 input switches. It is controlled from a host computer via the Bluetooth communication...
In order to improve the unmanned sales of agricultural products, we are researching and developing an Unmanned Agricultural Product Sales (UAPS) system combining an embedded system called the UAPS shop system, a server system and a mobile system. Up to date, implementation of the UAPS shop system and an initial prototyping of the sever/mobile system have been completed and evaluated. This paper describes...
In this paper, we propose a stand-alone mobile visual search system based on binary features and bag of visual words framework. The contribution of this paper is two-fold: (1) a visual word-dependent substring extraction method is proposed; (2) a modified version of the local NBNN scoring method is proposed in the context of image retrieval. The proposed system improves retrieval accuracy by 11% compared...
A mobile robotic access point (AP) is proposed to provide better wireless network environment. This AP automatically searches and moves to the best position to provide enough radio power for all devices connected to the AP. We designed the mobile robotic AP and evaluate its performance in experiment. It was found that the proposed AP can increase radio power for all devices connected to the AP by...
TV sets and companion devices (Smartphones, Tablets, etc.) have outgrown their original purpose and are now playing together an important role to offer the best user experience on multiple screens. However, the collaboration between TV and companion applications faces challenges that go beyond traditional single screen applications. These range from discovery, wake-up and pairing of devices, to application...
Extending battery life for smartphones while using wireless networks is important. In this paper, we propose Comfort Route for Energy Saving (CRFES), which helps users extend the battery life of their smartphones by navigating to their destinations via Quality of Service (QoS)-compliant energy-efficient spots such as Wi-Fi spots. To create CRFES, we construct maps of Wi-Fi spots using logging software...
In this paper, we propose an App Quick Sieve/Verify Scheme (AQSVS) to improve the App safety/quality verification issue in the third-party or enterprise app market place. The concerns related to app store safety are of paramount interest as and an increasing number of malware and defective apps caused by Android fragmentation. The AQSVS based on the use of App package information and TF/IDF inverted...
This paper investigates Quality of Service (QoS) of personal mobile wireless LANs (m-WLANs). QoS characteristics in densely located WLAN are found to be significantly different from that in traditional WLANs. The channel assignment method is proposed and evaluated by using real devices to accurately evaluate the interferences for the total throughput of the densely located m-WLANs.
This university has published the “MMDAgent” voice interaction system toolkit as opensource software. MMDAgent enables users to develop voice interaction system easily by editing the voice interaction scenario based on Finite State Transducer (FST) format. However, having numerous people edit it simultaneously is difficult. For that reason, tremendous labor costs are necessary to describe an abundant...
Anonymization is a common technique for publishing a location data set in a privacy-preserving way. However, such an anonymized data set lacks trajectory information of users, which could be beneficial to many location-based analytic services. In this paper, we present a dynamic pseudonym scheme for constructing alternate possible paths of mobile users to protect their location privacy. We introduce...
With the increasing demand for video streaming in mobile environment, we have been tackling a research on throughput prediction based on the measurement history data in order to improve service quality[1][2]. Since throughput fluctuation occurs sharply in mobile environment, useless packet loss or congestion occurs when available network bandwidth is insufficient compared to the bit rate of video...
In this paper we present a simple and convenient user interface for the elderly with an open source system platform used in smartphones. This design provides a simplified interface, a large font, a big button and a simple user interface starter for easy operation, and offers the elderly a method for those who are more accustomed to dial phones. Our design includes an improved selective reply text...
