The main objective of this work is to develop an electronic travel aid to assist the blinds for obstacle identification in their navigation. This navigation assistance for visually impaired (NAVI) system presented in this paper consists of a single board processing system (SBPS), a vision sensor mounted headgear and a pair of stereo earphones. The image environment in front of the blind is capt...

We have developed a “WBS(Work Breakdown Structure) process model” for a business application software development project. We have also developed a project management system called “PRO-NAVI” which works on the “WBS process model.” This WBS process model” provides (1) mutual mapping between the “software development processes”, “activities”, “products”, “know-how,” “rules”, and “standards”, and...

In radiotherapy, setup precision has great influence on the therapeutic effect. In addition, body movements during the irradiation and physical alternations during the treatment period might cause deviation from the planned irradiation dosage distribution. Both of these factors could undesirably influence the dose absorbed by the target. In order to solve these problems, we developed the "body ...

We present an object identification methodology applied in a navigation assistance for visually impaired (NAVI) system. The NAVI has a single board processing system (SBPS), a digital video camera mounted headgear, and a pair of stereo earphones. The captured image from the camera is processed by the SBPS to generate a specially structured stereo sound suitable for vision impaired people in und...

Crop nitrogen nutrition is an important indicator for evaluating crop growth. Rapid and non-destructive estimation of accumulation in wheat leaves great significance fertilizer management. Based on field test data from multiple varieties different locations, years, levels, growth periods, the relationship between 11 canopy hyperspectral parameters plants was studied. According to results correl...

This paper describes experimental results of WEB Navigational Retrieval Subtask 2 (WEB Navi-2). We made three gram-based indices, namely indices for text in whole page, text in title tag and text in anchor tag. Since gram-based indices are able to index all strings in target text, words that are not found in dictionaries are also indexed essentially. We used words in TITLE tag of search topics ...

In the Navigational Retrieval Subtask 2 (Navi-2) at the NTCIR-5 WEB Task, a hypothetical user knows a specific item (e.g., a product, company, and person) and requires to find one or more representative Web pages related to the item. This paper describes our system participated in the Navi-2 subtask and reports the evaluation results of our system. Our system uses three types of information obt...

In this paper the role of object identification in sanification system for Navigation Assistance Visually Impaired (NAVI) is discussed. The developed system includes Single Board Processing System (SBPS), vision sensor mounted headgear and stereo earphones. The vision sensor captures the vision information in front of blind user. The captured image is processed to identify the object in the ima...

This paper provides a development concept of wireless localization network, which is used for the navigation of indoor robots. Prior to presenting the concept, a brief review about the indoor localization system is provided as a preliminary background material of this research. This paper introduces three key developments in the URS localization system. They are so-called StarLITE, Navi-guider,...

The robots that will be needed in the near future are human-friendly robots that are able to coexist with human and support human effectively. To realize this, mobile robots should be controlled by the user easily and simply. This paper introduces a control system called “Navi-guider,” which is to provide the user with easy control of mobile robots. Navi-guider system could detect a length and ...
