1. 0:00Hello everyone. We are group one and we
2. 0:02will be presenting on Dragoon.
3. 0:05Dragoon is a VR controller providing
4. 0:07haptic feedback based on drag and weight
5. 0:10shift.
6. 0:11For the research background, they found
7. 0:13that most VR controllers provide only
8. 0:16limited haptic feedback like vibrations
9. 0:19and they are usually very lightweight
10. 0:21and can't realistically convey size,
11. 0:24resistance or inertia.
12. 0:26And for motivation, they found a few
13. 0:28studies based on mass distribution
14. 0:30sensations on at the fingertips and
15. 0:33physical connection.
16. 0:35And they made Dragoon which introduces a
17. 0:39new concept of a shape-changing VR
18. 0:42controller that can provide a dynamic
19. 0:45passive haptic feedback based on air
20. 0:48resistance and weight shift which
21. 0:49changes based on
22. 0:52which of the fans are open and how wide
23. 0:54they are open. So for example, if they
24. 0:56are both closed, then it will be more
25. 0:58like a long object like a sword. If they
26. 1:01are both half open, then it might be
27. 1:03like a small sign for example in the
28. 1:05scale
29. 1:06scenario down here.
30. 1:08And if they are both fully open, then it
31. 1:10could be a large item, a large flat item
32. 1:13like a shield.
33. 1:15And they also provided the prototype
34. 1:17which is consists mostly of
35. 1:20cheap or 3D printed parts.
36. 1:23And they also provided an evaluation
37. 1:26where they study how users perceive
38. 1:28Dragoon's feedback and how it compares
39. 1:31to
40. 1:32haptics provided by an equivalent
41. 1:33passive prompt.
42. 1:36And they also provide basic
43. 1:37recommendations for the application of
44. 1:39drag and weight shift base controllers
45. 1:41such as Dragoon.
46. 1:43And this was our first attempt at
47. 1:45organizing all of the related works. We
48. 1:48first organized them into six groups.
49. 1:51The first two being
50. 1:55changing the
51. 1:57uh, actual environment to adapt to the
52. 2:00virtual environment and then changing
53. 2:03the virtual environment to adapt to the
54. 2:05real environment. And the other four are
55. 2:07based on what kinds of
56. 2:10feedback they are. For example, impact,
57. 2:13resistance, te- uh,
58. 2:15texture, and weight. This was our second
59. 2:18attempt at categorizing all of the
60. 2:21related works. We first separated them
61. 2:23in ubiquitous into ubic ubiquitous type
62. 2:27displays, wearable and wearable type
63. 2:29displays. And in ubiquitous type
64. 2:31displays, we separated them into visual,
65. 2:34spatial, and touch. For visuals, they
66. 2:37are largely
67. 2:40projected onto real objects and using
68. 2:43the real objects to present the virtual
69. 2:47objects.
70. 2:48In spatial, they
71. 2:50change the actual space in order to
72. 2:54adapt to the virtual environment. And in
73. 2:56touch, they use
74. 2:58static
75. 3:00devices and air to provide a pressure,
76. 3:04uh, sense of pressure and texture.
77. 3:07In wearable type displays, they we
78. 3:09separated them into ones on the head and
79. 3:12one one's on the
80. 3:14limbs.
81. 3:15The ones on the head were mostly just VR
82. 3:18and AR helmets. And the ones on the
83. 3:20limbs were worn on the hands, fingers,
84. 3:25or on the legs.
85. 3:27And would directly provide stimulation
86. 3:32or impact.
87. 3:35And among those, we then separated them
88. 3:37into our two design spaces.
89. 3:40The first one was a on the ubiquitous
90. 3:43type designs, which the visual one and
91. 3:46we then separated them based on how much
92. 3:50stimulation was given. So, for the
93. 3:52visual ones, there wasn't a lot of
94. 3:55energy put into them, largely because
95. 3:57you probably can't
96. 3:59genuinely provide a lot of energy to the
97. 4:01eyes to avoid overstimulation.
98. 4:04And
99. 4:05in regards to space and touch, they were
100. 4:08pre- pretty evenly spaced out.
101. 4:11But when it comes to wearable devices,
102. 4:14there is a
103. 4:15like a very obvious
104. 4:18gap when it comes to
105. 4:21heavy energy on the head because the
106. 4:23head is
107. 4:25quite delicate and you can't really put
108. 4:27a lot of uh
109. 4:29how
110. 4:30power onto it. And lightweight
111. 4:34textural when it comes to uh textural
112. 4:38stimulation when it comes to the limbs
113. 4:42instead of the fingers.
114. 4:44So we decided to make one for the feet
115. 4:48where we wanted to create something that
116. 4:50could stimulate walking on a beach, for
117. 4:52example, because when you're walking on
118. 4:54the sand with your bare feet, it's not
119. 4:56something that you can usually
120. 4:58experience when you're not near the
121. 5:00beach. So we want to create something
122. 5:04like the AI-generated picture on the
123. 5:06left, which is
124. 5:09kind of a sandal that is a and the
125. 5:12bottom sole is replaced with a bag
126. 5:14filled with sand.
127. 5:17And it will be strapped onto the user's
128. 5:19foot.
129. 5:20And then in regards to the
130. 5:23actual experience, we want
131. 5:26to also add like fans blowing
132. 5:30wh- blowing mist, which might be
133. 5:34we we kind of want to add salt to the
134. 5:36mist to make to stimulate
135. 5:39like the actual seawater
136. 5:41because it's kind of salty.
137. 5:43But we aren't very sure about how that
138. 5:45works
139. 5:46uh if that would work properly yet. And
140. 5:48then we will also create a VR game based
141. 5:51around the user
142. 5:54walking on the sandals and with the mist
143. 5:57and fighting a beast on the beach.
144. 6:01And that is our presentation. Thank you.
