“…Devices that have been studied include IR tags (Want et al 1992), ultrasonic wave tags (Harter et al 1999), RFID tags (Amemiya et al 2004;Ni et al 2003), Wi-Fi (Bahl and Padmanabhan 2000), and UWB (Mizugaki et al 2007). If the device ID is registered with the system, the person carrying that specific device can be located and identified.…”

Providing personal and location-dependent services is one of the promising services in public spaces like a shopping mall. So far, sensors in the environment have reliably detected the current positions of humans, but it is difficult to identify people using these sensors. On the other hand, wearable devices can send their personal identity information, but precise position estimation remains problematic. In this paper, we propose a method of associating wearable accelerometers and foot tracking results using laser range finders in the environment. First we propose an association method based on signal correlation between biped foot and accelerometer. However, in crowded situations, sometimes only one foot of a pedestrian is observed because of occlusion. To cope with the problem, we propose a new evaluation function that focuses on the phase dependent correlation of cyclic walking behavior. Example results of tracking individuals in the environment confirm the effectiveness of this method.

“…It has been reported that tactile interaction can effectively assist pedestrians with visual impairments when crossing the street (Ross and Blasch 2000). As tactile-based navigational aids, vibrotactile stimulation systems that use several vibrators in the shape of a cap (Cassinelli et al 2006), rings (Amemiya et al 2004), a vest (Erp et al 2005), belt (Tan et al 2003;Heuten et al 2008), and glove (Zelek et al 2003) have been proposed. Unfortunately, these tactile approaches require that users learn how to convert stimuli to information.…”

“…We used the RFID tag space [16] for the wide-space positioning system. This system can detect the user's position and gain the position data through the RFID tag reader (RF Code CO., Spider) which reads the ID of the RFID buried in a reticular pattern at intervals of 1.2 [m].…”

“…The odor strength was measured at ten-minute intervals with the odor-measuring device using the model of the nasal fossa. It was found that with 0.05 [ml] of perfume material, prototype 1 could present an odor strength of 16 [Hz] at maximum. It was also revealed that the duration of presenting an odor strength of 16 [Hz] was less than 10 minutes.…”

Recently, there are various types of display systems that can present aural, visual and haptic information related to the user's position. It is also important to present olfactory information related to the user's position, and we focus on the spatiality of odor, which is one of its characteristics. In this research, we constructed and evaluated a wearable olfactory display to present the spatiality of odor in an outdoor environment. The prototype wearable olfactory display system treats odor in the gaseous state, and the odor air is conveyed to the user's nose through tubes. Using this system, we also present the spatiality of odor by controlling the odor strength according to the positions of the user and the odor source. With this prototype system, the user can specify the position of the odor source in an outdoor environment. To improve this prototype system, we constructed another wearable olfactory display. Because odor is treated in the gaseous state, the first prototype system has some problems such as the large size of the device and unintentional leakage of the odor into the environment. To solve these issues, we developed and evaluated an advanced wearable olfactory display that uses an inkjet head device to treat odor in the liquid state.
