InGaN/GaN multiple quantum well (MQW) nano-scale light emitting diodes (nano-LEDs) were fabricated by a hydrogen environment anisotropic thermal etching (HEATE) technique. HEATE is a GaN selective etching technique using SiO2 masks based on thermal decomposition reaction of GaN in hydrogen environment at high-temperature around 800 1100°C. An InGaN/GaN MQW blue LED epitaxial wafer grown on (0001)...
Due to human sensitivity for humanlike objects, designing human-like behavior for a robot that interacts with humans remains a central issue in the HRI field. This issue is formidable because human-likeness is an important factor for better interaction since it can easily convey negative impressions if the design is not perfect, as in the uncanny valley phenomena. This paper addresses this issue with...
As a promising wireless access standard for machine-to-machine (M2M) networks, the IEEE 802.11 task group ah has been discussing a new standard which is based on the wireless local area network (WLAN) standard. This new standard will support an enormous number of stations (STAs) such as 6000 STAs. To mitigate degradation of the throughput and delay performance in WLANs that employ a carrier sense...
In a field experiment with N = 75 participants, the android telecommunication robot Telenoid was introduced in three different ways: participants either read a short story presenting the Telenoid as character, a non-narrative information leaflet about it, or they received no preliminary introduction at all before interacting with the robot. Perceived usefulness and behavioral intentions to adopt the...
This paper outlines our ongoing project, which aims to investigate the effects of robot embodiment and operator modality on an operator's task efficiency and concomitant level of copresence in remote social interaction. After a brief introduction to related work has been given, five research questions are presented. We discuss how these relate to our choice of the two robotic embodiments “DARYL” and...
Because of the global warming issue, the attention to renewable energy such as photovoltaic generations has increased. It is assumed that a lot of photovoltaic generations will be installed in the future according to Japanese government plans to install 28GW by 2020 and 53GW by 2030. However, it is expected that, when the load demand is low, surplus power occurs in the power system with a large penetration...
We previously investigated body ownership transfer to a teleoperated android body caused by motion synchronization between the robot and its operator. Although visual feedback is the only information provided from the robot, due to body ownership transfer, some operators feel as if they were touched when the robot's body was touched. This illusion can help operators transfer their presence to the...
In this study, we examine the factors with which robots are recognized as social beings. Participants joined sessions of the Ultimatum Game, a procedure commonly used for examining attitudes toward others in the fields of economics and social psychology. Several agents differing in their appearances are tested with speech stimuli that are expected to induce a mentalizing effect toward the agents....
Teleoperated androids, which are robots with humanlike appearances, are being produced as new media of human relationships. We explored the potential of humanoid robots and how they affect people in the real world when they are employed to express a telecommunication presence and a sense of ‘being there’. We introduced Telenoid, a teleoperated android, to a residential care facility to see how the...
In recent years, research has increased on very human-like androids, generally investigating the following: (1) how people treat such very human-like androids and (2) whether it is possible to replace such existing communication media as telephones or TV conference systems with androids as a communication medium. We found that androids have advantages over humans in specific contexts. For example,...
Recent GPUs, which have many processing units connected with a global memory, can be used for general purpose parallel computation. Users can develop parallel programs running on GPUs using programming architecture called CUDA (Compute Unified Device Architecture). The main contribution of this paper is to implement a Canny edge detection algorithm on CUDA. The experimental result shows that our implementation...
