Image Processing of 2-Dimensional Barcode

QR (Quick Response) codes are frequently used with progress of the Internet and introducing the QR decoding function in the cellular phone. A bar code shows an individual identification number (ID) by this number fundamentally. As the amount of information encoded by one-dimensional bar codes is limited, two-dimensional bar codes have been developed. This paper presents the dotted picture or image multiplexing method over the QR coding and the evaluation of the redundancy characteristics of the QR coding. Then, the animation method of image QR code is presented. The prototype of the QR Editor for making the QR code with the dotted pictures or image has been developed and the dotted pictures reading characteristics are confirmed by the cellular phone barcode reader.

An Interactive Learning System Using Smartphone for Improving Students Learning Motivation

The number of smartphonesis increased exponentially and they are promising tools for interactive learning during lectures in the universities. However, when in a lecture roomtens of sets of smartphones want to make simultaneous connection by Wi-Fi, the traffic will be increased and the network will be congested. In this study, we examined the effective use of the smartphones during the lectures. We considereda method of acquiring/utilizing the study records, which improves the students’learning motivation. In this research, we use smartphones as information terminals and carried out experiments in a real lecture room. The proposed method improves the degree of lecture understanding, thus improving students’ learning motivation.

An Active Learning System Using Smartphone for Improving Students Learning Concentration

In our previous work, it has been shown that the students can improve the learning process by using smartphones. For the professors of the university, it is difficult to offer all necessary information to the students. In addition, they cannot provide the information to satisfy all students because the quantity of knowledge of each student attending a lecture is different. Therefore, for the lectures of a higher level than intermediate level, the students should study the learning materials by themselves. In the previous work, it was presented an interactive learning process in order to improve the students learning motivation and the self-learning time. However, the progress speed of a lecture was not good. In this paper, to solve this problem, we propose an active learning system for students self-learning.

In our previous work, it has been shown that the students can improve the learning process by using smartphones. The professors of the university cannot provide the information to satisfy all students because the quantity of knowledge of each student attending a lecture is different. Therefore, for the lectures of a higher level than intermediate level, the students should study the learning materials by themselves. In the previous work, we presented an interactive learning process in order to improve the students learning motivation and the self-learning time. To improve the progress speed of a lecture, we proposed an Active Learning System (ALS). Also, we introduced a procedure for Self-learning by adding some functions in order to improve the efficiency of the Self-learning. In this paper, we performed experimental evaluation of our ALS. The results showed that the proposed ALS can improve student self-learning and concentration.

A User Attestation System Using a Cellular Phone Equipped with Digital Camera

For accessing Internet, a reusable password method is frequently used because of its simplicity. This reusable password method is very vulnerable. In recent years, with the explosive growth of the Internet user, user passwords are often incorrect handled and this attestation system is very dangerous. To solve these vulnerability problems of the attestation system, the one-time password, biometric system, and other methods using IC or LSI chips have been developed to build more complex authentication systems. But, still remain many problems such as system complexity and certification costs. In order to provide a low-cost and simple user attestation method, we propose a new method with strong authentication by using digital camera of cellular phone. In this paper, we present the system outline and the characteristics of the proposed system. The efficiency of the proposed attestation method is confirmed by an experimental prototype system.

Improvement of Study Logging System for Active Learning Using Smartphone

In general, it is difficult for the professors of universities to provide all needed information to satisfy the students because they have different knowledge and interests. To solve this difficulty, our previous work suggested an interactive learning process, which use the students’ study records in order to improve the students’ learning motivation and the self-learning time. To improve the progress speed of a lecture and the efficiency of the Self-learning, we proposed an Active Learning System (ALS) using smartphone. In addition, we performed experimental evaluation of our ALS and showed that the proposed ALS can improve student self-learning and concentration. Learning system that has been proposed so far, was only to give a feedback a record of student’s learnings to lecturer. In this paper, we propose a mechanism to enhance the learning effects by logging a record of students’ learnings in the whole process of learning system.

Image recognitions of collaborative drones' security controls for FPV systems

With the recent growth of the Drones market, the first person view (FPV) by drones are spreading in various usages such as the promotions or TV programs. However, it is considered that the drones accidents are getting serious problems because of the failures of the operations or malfunctions. Therefore, this paper proposes the collaborative security control systems by multiple drones for the FPV systems, and the image recognition methods of the prototype system are presented. Then, the prototype system used in the open campus events, and the reports of the field usages are discussed for the future studies.

To solve this problem, we proposed the interface of smartphone on our ALS to improve the learning concentration. In this paper, we show the performance evaluation of ALS that use improved human interface on the mobile devices. The evaluation results show that the interactive lecture using ALS increases the students’ concentration.
