Games are often cited for their inherent qualities that make them engaging, inspiring, fun and easy to learn. In education, two separate tracks of game-based learning and gamification have sought to activate the benefits of games and game design for the sake of better learning. This paper examines the strengths and weaknesses of games and gamification to propose an approach that focuses not on motivating with rewards and consequences, but instead on providing intrinsic game-like experiences through play. We address the issue of gamifying educational contexts with discussions about gamer motivations, the relationship between games and play, and designs for optimal learning within games. From the theoretical foundations of behavioral psychology, anthropology and game studies, we then conclude with a model for the design and evaluation of playful experiences in systems of learning inspired by game design.

This paper discusses the transient error problem on Application Specific Integrated Circuit (ASIC). It focuses especially on the storage part (register) of ASIC since the transient error on registers can be quickly propagated to the other part of the system. It proposes a novel Error Correcting Code (ECC)-based high-level synthesis where ECC modules are suitably controlled to maximize the reliability of ASIC with low cost. It also proposes an integer linear programming-based method to minimize the number of ECC modules, and demonstrated examples show the effectiveness of the proposed method. © 2016 IEEE.

In order to measure friction coefficients of tire grounding surfaces in car running, a simple cantilever-type tactile sensor that can detect the vertical load and friction force applied to the sensing part as well as direction of the friction force, simultaneously, has been proposed. The present study equips the proposed sensor to a tire and confirms that the sensor can measure the friction coefficient of the tire grounding surface. For this purpose, measurements in this study were conducted using a sensor under a similar load as that of a common automobile travelling in an arbitrary direction. In order to perform the experiments under a high load in an arbitrary direction, we developed a parallel mechanism-type tire-driving device. The developed device can apply a high load to the tire in an arbitrary direction and can measure the vertical load, friction force, and the direction of the friction force applied to the tire involving the sensor. Thus, the measurement accuracy of the proposed sensor can be verified by comparing the output of the sensor to that of the driving device. As a result of this study, we clarified that the measurement values of the sensor are affected by the deformation of the tire, and proposed a method for correcting the effect of the tire deformation. By introducing the proposed correction method to the measurement of the sensor, it was confirmed that the friction coefficients of various surfaces can be measured with sufficient accuracy under a practical high-load condition. © 2017 Society for Experimental Mechanics

With the growing scale of integration, it is demand for next-generation VLSI design to consider not only the number of resources, but also the bitwidths of them. Removing wasted bits of resources, the area and power costs are optimized rather than conventional design. This paper shows that intentional clock skew (useful clock skew) is effective to improve the performance of bitwidth-aware circuits, and formulates a novel problem of clock skew scheduling to minimize the clock period during register allocation and binding under the total bitwidth constraint. A mixed integer linear programming-based approach is presented to formally draw up the problem. Experimental results show that the proposed approach can reduce 9.4% clock period on average over the conventional design. © 2015 IEEE.

Typical applications of gamification in education use either game mechanics to encourage positive engagement behaviors or full games to deliver educational content; however, both approaches raise some concerns. Game mechanics can distract from the intrinsic enjoyment of activities while full games construct learning contexts that may be significantly different from the real-world contexts of the targeted subject matter. This paper aims to highlight issues of behavioral conditioning and knowledge transfer in instructional design that uses gamification by examining foundational theories and recent studies. We propose a design approach called "gameful learning" that focuses on integrating intrinsically rewarding, playful aspects of game-like experiences into authentic learning activities. Authentic learning activities relate real-world contexts to classroom learning while the desired motivational outcomes of playful experiences are shown to be more fulfilling than extrinsic rewards.Wethen investigate playful experiences in a game-based learning activity integrated into a business English class at a Japanese technical college. In the activity, mixed teams of Japanese and Singaporean students (N = 47) competed at negotiating for resources required to establish businesses within the specified time limits. The results of our analysis show the experiences of arousal, contest, and discovery were the most prevalent in the game. Levels of arousal and thrill showed the strongest positive correlations to enjoyment, implying the students had approached the activity with a playful attitude rather than a serious one. The Japanese students' reported levels of engagement in the contest and experiences of achievement correlated strongly with their sense of challenge. These results and their implications for the development of a playful affordances model as a tool for the design of gamification and gamebased learning activities are the focus of this paper. © 2016 TEMPUS Publications.

We propose a simple steganalytic scheme for least significant bit embedding. The new method is based on statistics of image difference signal, and enables us to estimate the relative message length with such a high accuracy as Sample Pairs Analysis. Experimental results show that our method detects a stego Work which is missed by Sample Pairs Analysis, and vice versa. This implies that a combination of several steganalytic techniques should be used to reduce the missing rate. We believe our method is one of useful tools for LSB steganalysis. © 2010 IEEE.

In a class focused on practical programming, it is not uncommon to find a large difference in student ability levels. When such a gap in proficiency exists, students with a high level of understanding tend to find the class too simple and as a result their motivation decreases. Up until this point, we have been responding to students who have a lower level of understanding by providing them with supplementary work in order to help them reach a core competency level. On the other hand, there has not been any corresponding action on behalf of students who already have a high level of achievement. We have created a special environment with the aim of enabling students who already have a high level of technical ability to progress with self-directed free study in the areas of programming and networking. This free space is called the Sandbox. The results thus far include daily use by a number of students and the voluntary implementation of student-run programming contests. We have observed an increase in the motivation level of the students who are participating in these activities. © 2015 IEEE.

We have studied the object silhouettes and surface direction through the stereo matching image processing to recognize the position, size and surface direction of the object. For this study we construct the pixel number change distribution of the HSI color component level, the binary component level image by the standard deviation threshold, the 4 directional pixels connectivity filter, the surface elements correspondence by the stereo matching and the projection rule relation. We note that the HSI color component level change tendency of the object image near the focus position is more stable than the HSI color component level change tendency of the object image over the unfocused range. We use the HSI color component level images near the fine focused position to extract the object silhouette. We extract the object silhouette properly. We find the surface direction of the object by the pixel numbers of the correspondence surface areas and the projection cosine rule after the stereo matching image processing by the characteristic areas and the synthesized colors. The epipolar geometry is used in this study because a pair of imager is arranged on the same epipolar plane. The surface direction detection results in the proper angle calculation. The construction of the object silhouettes and the surface direction detection of the object are realized. © 2015 SPIE.
