１.論文の評価 
This dissertation makes significant theoretical and empirical contributions regarding synergized 
interactions to the field of human-engaged computing. Theoretically, it shifts from high-level 
concepts to empirical studies in interactions. The introduction of the FSIRA framework which 
incorporates the rhythm-based adjustment mechanisms offers a novel, practical approach to 
synergized interactions. This framework provides a more nuanced understanding of synergized 
interactions and bridges the gap between theory and practical design. 
Empirically, the dissertation presents the first comparative analysis of three one-way interaction 
modes and introduces the first two-way interactive system for synergized interactions. This 
innovative system demonstrates superior performance over traditional one-way interactive systems, 
marking a potential technological revolution in Human-Computer Interaction (HCI). The 
development of interactive systems for walking creativity and running meditation extends 
theoretical perspectives and addresses gaps in current research. The integration of synergized 
interaction theory to curriculum design in educational technology introduces inventive methods for 
enhancing student engagement with digital tools, potentially inspiring future research in 
technology-enhanced learning. By exploring synergized interactions in digital health and education, 
the dissertation establishes a foundation for future advancements while offering practical 
guidelines for HCI design. 
This dissertation not only advances theoretical understanding of synergized interactions but also 
drives innovation in the industry by demonstrating the practical benefits of synergized interactions 
and setting new standards for the design of interactive technologies.

論 文 内 容 の 要 旨 
 
This Ph.D. thesis explores the edge-enhanced microscope of phase-amplitude objects, 
which is an essential technique in optical information processing that highlights 
object contours. It finds application in various fields, including image processing, 
microscopy, biological imaging, fingerprint recognition, and astronomy. 
   In the field of biological research, the traditional imaging technique is the bright-
field microscope, which can observe opaque amplitude objects but yields low-contrast 
images for transparent phase objects. To address the limitations of the bright-field 
microscope, microscopist developed phase-contrast microscopes that enable the 
observation of transparent phase objects but do not enhance the objects’ edges. As a 
more advanced microscope, the differential interference-contrast microscope can 
enhance the edges of both amplitude and phase objects, which was not possible with 
previous microscopes. Nevertheless, it still presents a constraint in terms of only 
one-directional edge enhancement. Recognizing this one-directional limitation, 
opticians and microscopists redirected their focus to the edge-enhanced microscope 
in which a vortex filter is used to alter the phase of light, providing all-directional 
edge enhancement and detailed information about transparent samples, such as 
biological cells. A vortex filter is placed on the Fourier plane of the 4f system to 
enhance the edges of objects in all-directions. Generally, the vortex filter is classified 
into two types: scalar and vectorial vortex filterings. When a spiral phase filter is 
generated by a spatial light modulator or a vortex phase plate in a 4f system, it 
exhibits scalar vortex filtering, whereas a q-plate or an s-wave plate, which is a 
spatially variable half-waveplate placed in a 4f system exhibits vectorial vortex 
filtering. 
   Recently, a 4f system containing a q-plate has been used to perform edge 
detection and enhancement of amplitude or phase objects. However, only a few 
studies have concentrated on edge enhancement of complex phase-amplitude objects 
and the details of edges present in phase-amplitude objects have not been analyzed 
so far. Moreover, despite the previous studies being promising on edge enhancement 
of the phase-amplitude objects, a detailed analysis of functional differences between 
scalar and vectorial vortex filterings has not been experimentally conducted so far. 
Therefore, in the first part of this study, we experimentally verified the functional 
differences between scalar and vectorial vortex filtering with the q-plate using an 
onion cell, which contains the cell wall as amplitude object and cell nucleus as a 
phase object. The scalar vortex filtering image shows that the intensity of edges of 
the phase and amplitude objects was either reduced or increased due to their 
interference, while the vectorial vortex filtering image does not exhibit a change in 
the intensity of edges of the phase and amplitude objects. The intensity at the 
reduced edge in scalar vortex filtering image was three times lower compared to that 
of the vectorial vortex filtering image at the same position. 
   Our first part of the studies revealed that vectorial vortex filtering offers 
advantages over scalar vortex filtering and the vectorial vortex filtering successfully 
enhanced the edges of phase and amplitude objects in the phase-amplitude object. 
One problem, however, is the indistinguishability of the equally-enhanced edges of 
the phase and amplitude objects. In biological imaging, isolating phase object edges 
from an amplitude object is crucial for improving the visualization of phase-
amplitude objects. As far as we are concerned, there are no studies on the isolation 
of edges of the phase object from the edges of the amplitude object. To address this 
issue, we propose a method to isolate phase object edges from the amplitude object 
edges using an off-axis vortex filter (q-plate) as our second part of the study. We used 
vectorial vortex filtering for this purpose because scalar vortex filtering cannot 
achieve the isolation of phase object edges. Herein, we combined off-axis q-plates 
with four different displacements to isolate the phase object edge from the amplitude 
object. To demonstrate the proposed method, we conducted experiments using two 
distinct samples: the first sample comprised a phase test target surrounded by an 
aperture and the second sample involved an overlap between the phase test target 
and a white hair with non-zero transmittance. In the samples, the isolated phase 
object edge agreed well with the requirements of theoretical expectations and the 
amplitude object edge was reduced by approximately 93%. 
   Since the previous work on the edge-enhanced microscope was conducted in the 
visible wavelength range, there arises a need to extend its applications to the 
invisible wavelength spectrum (near-infrared imaging), which would be important 
for near-infrared fluorescence and electronic circuit inspection through silicon 
semiconductor. However, digital cameras, such as silicon-based charge-coupled 
devices and complementary metal-oxide-semiconductors, tend to become expensive 
when operating in the invisible wavelength range. To address this issue, researchers 
have opted for a more cost-effective approach by utilizing single-pixel detectors with 
reconstruction of two-dimensional image by correlation calculation. Therefore, the 
third part of the study is dedicated to the implementation of a single-pixel edge 
enhancement, thereby extending the capabilities and applications of our previous 
work on the edge-enhanced microscope. 
   Researchers attempted to integrate single-pixel imaging into an edge-enhanced 
microscope, where Fourier single-pixel imaging was adopted to capture the edges of 
the phase object using four or three-step phase shifting. While this method 
successfully detected and enhanced the edges of the phase object, the drawback is 
that due to the four or three-step phase shifting, resulting in four or three times 
single-pixel measurements are required for reconstruction. One advantage of their 
approach is the absence of a vortex filter; instead, they utilized a digital micromirror 
device to generate a reference wave and a vortex filter with the assistance of a super-
pixel technique. Recognizing the need to minimize the number of single-pixel 
measurements, we propose a method, namely, a single-pixel edge- enhanced 
microscope via convolutional filtering. We conducted numerical simulations to 
validate this approach, achieving a 75% reduction in single-pixel measurements 
compared to previous studies. The simulation results shows that the correlation 
coefficient of edge enhancement of the object through our proposed method and ideal 
edge enhancement is 0.89, which indicates that the proposed method is indeed 
capable of effectively enhancing the edges of objects. We plan to demonstrate our 
proposed method experimentally using both visible and near-infrared light in the 
future. First, we will carry out experiments to enhance the edges of the object and 
then isolate the edges of the phase object from an amplitude object.
