Remote coaching system for runner's form with wearable wireless sensor

This paper describes a remote training which supports the coaching of runners form by applying wearable wireless sensors. The system provides a trainer with kinematic information about exercise behaviour of a trainee through monitoring the arm swing with the tri-axial accelerometer in real time. While a trainer can advise the improvement of body movement on a web browser, a trainee can receive the indication during running as a sound feedback. We have designed and implemented our proposal. From the result of an experiment, it was found that the system contributed to the stabilisation of the running form through trainers appropriate advice.

Organizing online learning-community based on the real world log

Physical activities beginners encounter difficulties in being accustomed to their new level of activity for lack of constant motivation in regular physical activities. In order to keep a high level of motivation, the selection of a proper training partner is of significant importance. At present, SNS (Social Networking Service) provides a perfect opportunity to successfully find such an appropriate partner. This paper proposes a methodology for organizing an online community based on the real world log. During training, users will have tiny loggers on, such as GPS (Global Positioning System) and/or HRM (Heart Rate Monitor). After training, users will send the log file from the hardware devices to the system. The system aims at automatically organizes the appropriate community to increase or keep their motivation. This paper reports the design and development of the referred system.

Designing the web-community for self-managed training of runners

Running is an easy excise that can be carried out alone. If one commits to a community of running, s/he is able to acquire more positive effects from viewpoints of sustainability, skill polishing-up and motivation than alone. This study designs and develops a web-community, which offers community members an environment of self-management on running. They can set targets of running concretely based on individual purpose. For sake of achieving each target through the environment, the system proposes two important functions, which are configuration of a community and evaluation of running purpose, in addition to monitoring technologies.

Bridging multiple motor-skills in a community site

This paper touches upon the design issue for multiple skill development of human beings in an online community environment. It focuses on motor skills such as rope-skipping, running, swimming and so forth in the physical world. The approach attempts to adopt social networking service for mutual contribution on that purpose as the base of online communication. In order to treat various sorts of skill, the web-based system allows community authors to handle several types of media for storing records of skill training of individuals and representing them in the system. This study developed such an environment and made trial use for the first stage.

Hand-motion Analysis for Development of Double-unders Skill

Abstract Double-unders is one of interesting physical skills combining multiple primitive motions of different frequencies. This paper discusses an analyzing method of trajectory on hand-motion in double-unders. It also tackles to design an environment for the staged learning in acquisition process of the skill. We focus on the radius of motion-trajectory of the hand and spatial positions of moving hand. We measure some parameters relating to the hand-motions, and observe relative hand positions to the body. Then, we observe the difference of them between persons who have acquired the skill and others who have not acquired the skill yet. As a result, it has clarified that our proposal relating to the hand-motions is not irrelevant to success or failure of double-unders.

System design to improve running-form with motion-capture

In this paper, we propose a system to help learners improve the running form by the motion-capture system. We can capture the running form along with the time processing by this system. The system assumes the ideal running form that keeps the stable style. An ideal form is given by an expert. The system detects and represents the difference between learners form and pre-defined ideal form. In order for that, the system compares the current form with an ideal form that is represented by three-dimensional values. In our system, an ideal running-form is previously defined. The system also presents an advice of improving the running-form for learners.

Supporting multi-step annotation to promote reflective learning: triggered by a cell-phone

Many universities officially permit their students to use cell-phone as an input device in lectures. Considering this situation, this paper proposes a multi-step annotation function using a cell-phone as the trigger to start reflective learning. Using the proposed system during the lecture, students are required to mark the important slides via the cell-phone e-mail. This e-mail is synchronised to the respective slide automatically through the time stamp. Then, the student has to fulfil the annotation content marked by the e-mail after the lecture. This paper describes the design and development of the system, including the observed results of trial uses.

Design of the Community Site for Supporting Multiple Motor-Skill Development

Conventional approaches for computational support on complex motor skill acquisition and development are usually domain specific. However, today’s social web services allow members to facilitate the skill development from one to many types based on the detected shared parameters. This paper describes the design and development on a community site that supports motor-skill learning. Commitments to a community have strong advantage on both self-assessment and detection of the relative level about a skill. Moreover, some parameters among different skills might be the same in assessment of the acquired skills of individuals. Therefore, we design and implement the web-community system that integrates different skill-communities to interact each other. With respect to the technical interest, our environment offers users an authoring environment where they can adopt different types of modules to embed at the same time.

The Development of the System Which Creates Lecture Contents by a Combination of Various Units and Learning Contents

We developed the system which creates lecture contents by a combination of various units and learning contents. This system can divide lecture contents into each unit and learning contents by using syllabus metadata generated from the syllabus. This system also can create lecture contents combined with various units and learning contents from systemized lecture information. This paper describes a method to systematize relations between lecture and automatic generation of lecture contents combined with various units and learning contents from systemized lecture information.

A Sightseeing Guidebook Automatic Generation Printing System According to the Attribute of Tourist (KadaTabi)

Many sightseeing spots distributes sightseeing guidebooks of paper media at facilities such as tourist information centers, hotels, and stations which are the base of sightseeing. A paper sightseeing guidebook is valuable means to collect sightseeing information for tourists. However, from the tourist’s side, it is difficult to quickly find guidebook that one wants because too many kinds of guidebooks are distributed. From the information provider side, if the content of the guidebook changes, it is necessary to collect and correct the once distributed guidebooks and rebuild and redistribute. Also, there is a problem that it is impossible to grasp the use situation of the guide book. We developed the sightseeing guidebook automatic generation printing system according to the attribute of tourists (KadaTabi). KadaTabi is a system that creates recommended sightseeing guidebooks considering tourist attribute and sightseeing season and prints via a cloud printer. In this paper, we describe the development of a sightseeing guidebook automatic generation printing system according to tourist attributes (KadaTabi).
