During a user's transactions over the Internet, there are risks of unauthorised third party transactions carried out on the user's account, using the man-in-the-middle (MITM) attack and Trojan horse. In this paper, we propose a new interactive input method of sensitive information such as credit-card numbers and account numbers against these attacks. The proposing method relatively decides the input...
Many people have their own camera or recording devices such as cellar phones and digital cameras. When there is a big event, a lot of pictures and movies are taken from various places at the same time. People want to record events with their digital devices as a memory or remembrance. We have some services to share these photos and movies, however, there is no viewer suitable to summarize and integrate...
This paper proposes a new method that efficiently uses the RFID data collected from apparel shops. This method learns prediction models from the data by using data mining techniques. The models represent relationships between the number of sales in the next term and the actions of customers, such as the number of pick-up, the number of fitting, the number of customers, and so on. It is possible to...
Asaoka' method is a well-known method to predict settlement, and it is widely used for practical projects. Since Asaoka's method requires that the ground must be uniform, a problem in an un-uniform plane such as Haneda arises with respect to the application of Asaoka's method. This paper describes a method for an execution plans, experts choose the construction method and determine the constructions...
In this research, authors suggested one robot service in "Kukanchi". Therefore the authors developed the module which combined image recognition with voice recognition. By this module, the system recognizes movement and the utterance of the person. Furthermore, the system understands the intention of the person by using robot ontology in recognition contents. The service that understood...
This paper proposes a method that classifies bloggers according to their interests. The method calculates three kinds of similarities. That is, the method calculates similarities between target objects discussed in the blogs by using social annotations. Here, products, works, and services are examples of the target objects. Next, the method calculates similarities between impressions related to the...
This paper proposes a method that deals with missing values in the discovery of association rules. The method deals with items composed of attributes and attribute values. The method calculates two kinds of support. One is characteristic support and the other is possible support. The former is based on the number of examples that do not include missing values in attributes composing target items....
We propose a novel display technique that presents information with different visibility to multiple users. The system projects information on a screen through a revolving linear polarizer in front of the projector, and it shows information through another polarizer in front of the userpsilas viewpoint. The brightness of the observed information is reduced according to the relative angle of the polarization...
In this research, the environmental information interface where the person is kept is constructed as virtual-city separately for the phase corresponding to the scale. In addition, the installation of the marker etc. achieves the instruction by the gesture in natural shape without the necessity for the interface. The recognition speed and accuracy are shown to improve as results by using the vision...
This paper proposes a method that acquires a more appropriate classification model for label extraction. The model can extract specific labels from articles included in bulletin board sites. The labels represent the contents of the articles and are used to characterize the articles. The method selects two kinds of important examples not including a specific label by using expressions related to the...
This paper presents a gestual interaction system between human and robot using pointing movement based on 'humatronics'. The virtual room, which was based on physical room, can be shown an attended object with blinking. A user pointed out an object, which he/she wants to move. The robot moves to an indicated point, or moves an indicated object to point in physical room. Moreover, to interact at physical...
This paper proposes the sequential interestingness as a new evaluation criterion that evaluates a sequential pattern corresponding to the interests of analysts. The sequential pattern is composed of rows of item sets. The criterion satisfies the apriori property. Also, this paper proposes three attribute constraints. These constraints can naturally evaluate relationships of attributes both in an item...
This paper presents a gestural interaction system between human and robot using pointing movement. The virtual room, which was based on actual room, can be shown an attended object with blinking. A user pointed out an object, which he/she wants to move. The robot moves to an indicated point, or moves an indicated object to point in actual room. Moreover, to interact at actual rooms, the system that...
This paper presents human-robot interaction using pointing movements for a home robot. Pointing movement is an important communication tool in interpersonal communication. However, pointing has different means depending on a situation. We research that recognizes users' intentions by using their pointing in particular situations. Our aim is not to calculate accurately the point indicated by a user...
A 0.23 /spl mu/m single-chip Si-LDMOS high-power amplifier with matching circuits and all control blocks for quad-band GSM handset phones is implemented in 2.1/spl times/2.45 mm/sup 2/. The IC achieves a maximum PAE of 54% at 36 dBm output power and input VSWR of less than 1.6 over the GSM850/900 bands.
