In the mechanism how we perceive our environment, we use not only the sensor information, but also \"how it changes according to how we act.\" For example, we obtain the haptic information from the haptic sensor on our finger, and when we move our finger along to the surface of the touching object, the haptic information changes according to the finger motion, and we \"perceive\" the whole shape of the object by executing the action-and-sensing process. In other words, we have a high ability to \"integrate\" the relation of our body's action and its related sensing data, so as to improve the accuracy of sensor in our body. Based on this idea, we developed a simple perception aid device with user's explorer action, to perceive the object at a distance, which has a linked range sensor and haptic actuator, which we name \"FutureBody-Finger.\" The distance sensor measures the distance to the object (20--80[cm]), and it is converted to the angle of lever attached at the servo motor (0--60[deg]). The user holds this device in his hand with attaching his index finger on the device's lever. For the long distance to the object, the lever leans to the front, and the user feels nothing. On the other hand, for the short distance to the object, the lever stands vertically, and the user feels the existence of the object. Although the device simply measures the distance to the single point on the object, as the user \"explorers\" around him, the user can obtain more rich distance information of the surrounding object, and hence, finally perceive the shape of the whole object.","PeriodicalId":118940,"journal":{"name":"SIGGRAPH Asia 2014 Emerging Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122630592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People can touch objects on the touch panel display of the tablet PC or smartphone, but only get sensation of touching the surface of the display. Recently, some systems capable of inserting themselves into the display by using retractable stylus have been proposed. Beyond [Lee and Ishii 2010] is one of these systems. It consists of a retractable stylus, a table-top display, an infrared marker and a camera set at an environment. A virtual tip of the stylus is rendered when the retractable stylus is pushed to the table-top display. The head position of the user is detected by the infrared marker and the camera, and the virtual objects and the tip of the stylus are rendered properly according to the head's position. The system enables the user to interact with a virtual object under the table. However, the stylus dose not shrink or extend automatically because the stylus dose not have any actuators such as a motor. So the user is unable to feel the haptic sensation from the virtual object. It is necessary for the user to perceive the force from the virtual object to interact with the object more realistically. Another limitation is the fact that the system is stationary. ImpAct [Withana et al. 2010] is another interaction system with a smartphone and a retractable stylus. The force feedback is represented by simply stopping the shrinkage of the stylus. However, the system gives only the rigid force feedback without tactile sensations. And the system does not give a user the tactile sensation from the virtual objects. In addition, the system does not consider the viewpoint of the user.","PeriodicalId":118940,"journal":{"name":"SIGGRAPH Asia 2014 Emerging Technologies","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129611126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Having arms and hands synchronized with voluntary movements allows the user to feel robot's body as his body through visual, and haptic sensation. In this method, we introduce a novel technique that provides virtual arms for existing telexistence systems that does not have physical arms. Previous works [Mine et al. 1997; Poupyrev et al. 1998; Nedel et al. 2003] involved the study of using virtual representation of user hands in virtual environments for interactions. In this work, the virtual arms serves for several interactions in a physical remote environment, and most importantly they provide the user the sense of existence in that remote environment. These superimposed virtual arms follows the user's real-time arm movements and reacts to the dynamic lighting of real environment providing photorealistic rendering adapting to remote place lighting. Thus, it allows the user to have an experience of embodied enforcement towards the remote environment. Furthermore, these virtual arms can be extended to touch and feel unreachable remote objects, and to grab a functional virtual copy of a physical instance where device control is possible. This method does not only allow the user to experience a non-existing arm in telexistence, but also gives the ability to enforce remote environment in various ways.","PeriodicalId":118940,"journal":{"name":"SIGGRAPH Asia 2014 Emerging Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116695549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative data received from constructing and breaking A-Blocks can be valuable for various assessment applications (e.g., play therapy, cognitive testing, and education). In our prototype system, each block embeds a wireless measurement device that inclludes acceleration, angular velocity, and geomagnetic sensors to measure a block's spatial motion and posture during children's play. A standard set of blocks can be managed via Bluetooth in real time. By using combined sensor data, the system can estimate how to stack the blocks on each other by detecting surface collisions (Figure 1) and recognize many fundamental play action patterns (e.g., moving, stacking standing, waving) with SVM. Unlike existing block-shaped devices with phyysical constraints on their connections (e.g., electrical hooks, magnets), our solid and traditional-shaped block device supports flexible block play that could include more delicate motions reflecting a child's inner state (e.g., learning stages, stress level, representation of an imagination). These benefits of analyzing children's block play can be extended to allow for more enjoyable and interactive play, while social impacts include more constructive play.","PeriodicalId":118940,"journal":{"name":"SIGGRAPH Asia 2014 Emerging Technologies","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131868601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
