“…By using anamorphosis technique, UD-1 is able to display 3D image in front of a human's sight without any special devices such as HMD, special eye glasses, etc [2]. The projected image from UD-1 is actually 2D, but by psychological effect, a human perceives it as 3D.…”

This paper describes a projection based information display system which is called Ubiquitous Display. In usual cases, a man should approach information sources which are located around our living environment; e.g. bulletin boards, artificial signs, local maps, etc. However, the Ubiquitous Display is able to afford a human with relevant information by projecting it on where the human is looking such as a wall, a floor and a door so that the human does not need to move for seeking information. The Ubiquitous Display can make a user see 3D objects as well as 2D objects with naked eyes. Anamorphosis technique is adopted for a human to perceive a 3D structure from a 2D image by psychological effect. In this paper and video, how the Ubiquitous Display has been developed and its functions are introduced.

“…The 10 R-ST questions were chosen from 7 established ST tests to cover a wide range of transformations: Differential Aptitude Test (Bennett et al 1947), Purdue Spatial Visualization Test (Guay 1976), the Mental Cutting Test (College Entrance Examination Board 1939), Form Board Test and Hidden Figures test (Ekstrom and Harman 1976), Paper Folding test (Guilford and Lacey 1947), Snake In Cube test (Górska and Juscakova 2003). For the 10 NR-ST questions we introduced anamorphosis, a perspective technique that gives a distorted image which appears normal when viewed from a particular angle or with a suitable mirror or lens (Lee et al 2009; Čučaković and Paunović 2015) (see Figure 2).…”

Assessing Rigid and Non-Rigid Spatial Thinking

Spatial Thinking (ST) is an important part of reasoning. In contrast to Rigid ST (R-ST), Non-Rigid ST (NR-ST) has hardly been researched and tests do not exist, even though NR-ST is crucial for professions that deal with space and time such as engineering and design. Our study at 4 different universities confirms that R-ST does not predict performance in NR-ST; that performance in Non-Rigid ST is significantly lower than in R-ST; and that performance of students in later semesters is not better than in the first semesters. These results highlight the need for further research into NR-ST.

“…Anamorphic projection is used when projecting 3D geometry that does not exist in the physical scene (Figure 6c). A pre-distorted image is projected that appears three-dimensional when viewed from the user's vantage point [18] (Figure 7). For example, projecting a life-like character that appears to stand on the floor beside you.…”

a b c d e f Figure 1.HideOut is a mobile projector-based system that uses hidden markers (c,f) to map projected imagery onto tangible objects and surfaces (b,e) such as storybooks (a) and board games (d). ABSTRACTHideOut is a mobile projector-based system that enables new applications and interaction techniques with tangible objects and surfaces. HideOut uses a device mounted camera to detect hidden markers applied with infrared-absorbing ink. The obtrusive appearance of fiducial markers is avoided and the hidden marker surface doubles as a functional projection surface. We present example applications that demonstrate a wide range of interaction scenarios, including media navigation tools, interactive storytelling applications, and mobile games. We explore the design space enabled by the HideOut system and describe the hidden marker prototyping process. HideOut brings tangible objects to life for interaction with the physical world around us.
