Vection is an illusion sensation of self-motion provoked by watching visual oscillation. Traditionally, vection perception has been qualified using frequency responses. Indeed, the concept of frequency response is a common way to quantify the responses of visual oculomotor functions such as optokinetic nystagmus (OKN) and vestibular ocular reflex (VOR). This study explores whether frequency is the...
Vibrotactile stimulation to the gluteal or back regions through seats is a promising approach to deliver supplemental information to humans. Designing a method to achieve pleasant vibrotactile stimuli was addressed in this study, as such stimuli tend to result in unpleasant experiences for users. In particular, we investigated the properties of continual vibrotactile stimulation to the gluteal region...
In this paper, we develop a system to support learning of OpenFlow by visually associating controller configuration information and logical topology. In our system, the constructed topology is visually shown on a touchscreen display and a learner can easily confirm the topology. In addition, a learner can configure the controller by visual and simple operation using the touchscreen display. Therefore,...
The purpose of this research is to develop the real-world captioning system to ensure information accessibility for person with hearing impairment. However, switching the visual line between the speaker's face and the caption when one is engaging in conversation may stress the user. In this paper, we propose the real-world captioning system which display the dialog next to the speaker's face using...
A game space is designed and placed by considering the beats (Events or Quests) inducing the behaviors of a player. Beats of FPS game can be divided into three types. It is possible to evaluate the placement of the pieces of space in case of analyzing the visual cognition information obtained by the player depending on each kind of beat. In this paper, players were divided into two groups (Novices...
In this research, we present a practical method to detect the insufficient brushing points. The system consists of a sensor node and a visual interface. The sensor node can be clipped onto the handler of a toothbrush while brushing the teeth and the brushed regions will be realtime displayed on the visual interface. A six-axis inertial sensor inside the node is used to detect the scrubbed areas, so...
Many Internet of Things applications provide methods to create mashup services with if-then-else approaches due to its simplicity. When a number of mashup services are increased, it may be suffered by service conflict, that is, mashup services may perform opposite actions or abnormal behavior at the same time. To overcome this issue, this paper proposes the concept of context descriptor to detect...
Nowadays, people have to face many challenges In order to become familiar with all the functionalities of electronical devices. The training process becomes thus essential, especially when we are referring to consumer electronics created for people with disabilities. Our paper presents the importance of training visually impaired people for an advanced sensory substitution device. By using the advantages...
There is a visual novel which is a game combined with visual interaction and novel texts. We have challenged making an EPUB-type visual novel, because we can easily make it. The EPUB format is based on HTML5. In addition, We can get an easy way to make a visual novel with equations. Our visual novel gives us happy math.
Privacy violation cases are repeatedly reported by users of various photo sharing services. To avoid violating other's privacy unintentionally, visual abstraction techniques could be applied to blur photogenic persons at sufficient level so that they cannot be identified. From the result of our online survey conducted among 5,000 samples and Price Sensitive Measurement analysis, we succeeded in finding...
Even today "beeps" are mostly used in consumer electronics (CE) as user interface (UI) sounds. Though this has not changed for at least 10 years, we think UI sounds could be designed more useful and fascinated. This time we investigated what kinds of sound are used on recent CE UIs, and how users use and what they think of these sounds. As a result, users mostly understand the message when...
In the early years of college, students have the need to learn how to program in any programming language. It is important to see the differences between programming languages and their rules. We are proposing an interactive and self-study system for students to acquire the knowledge they need, from data structures to algorithms using multiple programming languages. The system gives the students some...
Image retargeting methods change the size of images to an arbitrary resolution while protecting visually important regions from distortion. Since retargeting methods deform contents of an image based on these importance, importance calculation methods suitable for image retargeting is needed. In this paper, we propose a framework to improve an importance map by using depth and segmentation information...
It is very challenging to generate a high dynamic range (HDR)-like low dynamic range (LDR) image, called wide dynamic range (WDR) image, without the ghost artifact from multiple differently exposed LDR images for dynamic scenes. Since the ghost artifact is caused by the moving objects in the input LDR images, it is required to properly detect the motion region to prevent the ghost artifact in the...
This paper proposes a multiview synthesis method for autostereoscopic (glasses-free) 3D displays. When a plurality of predetermined viewpoint images is generated from a limited number of input images, background information obscured by a foreground object in the input images may be represented by a hole in a new viewpoint image. The proposed method can restore the hole in the image while leaving structural...
In this paper we propose a novel method to improve the performance of image retrieval at VLAD (Vector of Locally Aggregated Descriptors) level. Our re-ranking algorithm uses relational graphs and the top-& neighborhood candidates to adaptively modify images similarity scores. The method is effective and increases the accuracy, without relying on low-level information or features geometrical verification.
Curvature, the second-order directional derivative of an image, has been widely used for image interpolation. However, conventional curvature-based interpolation (CBI) methods employ a time-consuming post processing to reduce visual artifacts such as blurring and jagging caused by the inaccurate estimation of the local curvature. In this paper, a novel fast CBI method is proposed which can precisely...
Small displays on wearable devices pose new challenges to presenting images. Image retargeting methods developed for mobile devices assume larger displays and are not adequate. This paper reports new approaches to image retargeting for wearable devices. Key to the proposed approach is identifying and presenting regions of interest that allows users to comprehend content and context. The system was...
In this study we present a hybrid scheme aiming at tone mapping high dynamic range (HDR) videos into low dynamic range (LDR), to achieve the best possible way of showing HDR content on LDR displays. The proposed scheme selectively tone maps different regions of each frame such that the visually important information is preserved. Then, it applies an average-based technique to ensure there is no sudden...
In this paper, we describe a new model of visual saliency by fusing results from existing saliency methods. We first briefly survey existing saliency models, and justify the fusion methods as they take advantage of the strengths of all existing works. Initial experiments indicate that the fused saliency methods generate results closer to the ground-truth than the original methods alone. We apply our...
