Making a tourist route corresponding to diverse sightseeing styles
Kouta Uejyou,Dongshik Kang,Hayao Miyagi 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
This paper proposes a tourist route corresponding to a diverse sightseeing styles. Matsuda[1] investigated the route which maximizes the sum of the worth within the time tourists can visit, assuming that the worth is given to each sightseeing spot. In addition Higa[2] had researched on the worth of sightseeing spots by questionnaire survey. He developed the creation of optimal route for sightseeing considering the tourists’ preferences based on AHP(Analytic Hierarchy Process)[3]. We present the new approach to make tourist route using AHP. In this method, We suggest the adoption value corresponding to sightseeing purposes in order to select the sightseeing spots.
A Cooking Support System using Gesture Recognition
Kouta Nishimura,Mitsunori Makino 대한전자공학회 2015 ITC-CSCC :International Technical Conference on Ci Vol.2015 No.6
In this paper, a cooking support system using gesture recognition is proposed, which encourages users to understand how to cook and reduces a time to cook. This system focuses on efficiency of the work and the operability of the system. This system is comprised of only smart glasses. Users can confirm a procedure while cooking by displaying recipes on smart glasses using augmented reality (AR). Users can change page without touching display or pushing button by using gesture recognition. From evaluation, it is seen that the proposed system is useful for the cooking by supporting users understanding how to cook and efficiently work. Therefore, the system is expected for person who usually do not cook to increase opportunities of cooking by simplifying users understanding how to cook. Through the use of the system, the system can contribute to their healthy lives. For the contribution, the system should be improved in processing time, sensitivity and usability.
GPU-based Acceleration of Minimum Vertex Covering for Large-scale Graphs
Kouta Toume,Hideki Kinjo,Morikazu Nakamura 대한전자공학회 2015 ITC-CSCC :International Technical Conference on Ci Vol.2015 No.6
Minimum vertex cover problems are one of the fundamental problems in graph theory and are known to be NP-hard. For structural data mining, we have proposed a GPU-based algorithm for minimum vertex cover problems. To derive sufficient parallelism for the many cores platform, the algorithm employs a distributed fashion for parallel operations, that is, GPU cores can basically perform their elemental operation only with their own data. Through the experimental evaluation, we demonstrate that our GPU algorithm implemented on both NVIDIA Fermi and Kepler GPU architectures is quite faster than a CPU version and the speedup becomes much evident when the graph size is enlarged.
Work Analysis of Small Size Sugarcane Harvester using GPS and On-board Camera in Okinawa Island
( Kouta Yokaryo ),( Senlin Guan ),( Takeshi Shikanai ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1
Although sugarcane is one of the most important crops in Okinawa, the yield of sugarcane per unit area is showing a downward trend because of soil hardening owing to the tread pressure of harvesters. If lightweight, small-sized harvesters with a narrow harvest width are used as alternatives, the problem of soil hardening can be resolved; however, the operational efficiency is expected to decrease. Though a small-sized 36-kW sugarcane harvester is available, its use is still not popular. Its introduction to harvesting work is delayed, because the work performance of this machine is unclear. In this research, we investigated the performance of a 36-kW harvester using a global positioning system and an on-board camera. Position information and image data were acquired and analyzed by a geographic information system. Using these data, the actual work condition of the harvester was determined to obtain its work efficiency.
Effect of haptic feedback on pseudo-haptic feedback for arm display
Mari Tatezono,Katsunari Sat,Kouta Minamizawa,Hideaki Nii,Naoki Kawakami,Susumu Tachi 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
We propose a haptic feedback system for an arm in order to obtain the sensation of stiffness and the boundaryof virtual objects. Powerful haptic displays are large and heavy, interfering with movement in the virtual environment.Here, we focus on an illusion called pseudo-haptic feedback, which provides the results of haptic feedback using onlyvisual impressions. Since pseudo-haptic feedback is known to be inappropriate for applications requiring strong force, acombination of pseudo-haptic feedback and real haptic feedback is proposed for a compact haptic display. This studyexamines the effectiveness of this combination by comparing the stiffness of two walls. Pseudo-haptic and real hapticfeedbacks are applied to one wall, and only real haptic feedback is applied to the other wall. The results verify that themagnitude of the force perceived with the application of a combination of pseudo-haptic and real haptic feedbacks isgreater than that of the force perceived by the application of only real haptic feedback.
