Projectagami CHI Work In Progress Paper


This week we worked on our CHI paper using the CHI 2015 Works in Progress template. We put a focus on concentrating on the wider use cases of our interactive device and implications of such a device in the future.

Below is the first page of our final paper.

Projectagami Final Literature Review


After the presentation of our device to the HCI group, we began to work on our CHI work in progress paper.

To do this, we felt it best to do a more extensive literature review. The main areas we focused on were 3D structures, shape shifting interaction and a self contained device.

Estimation of Folding Operation

Detecting origami folds
This paper investigates automated estimation of new folds in origami using ‘before’ and ‘after’ camera images. It uses a silhouette model, which is the outline of the paper from one viewpoint. When the user of the system makes a new fold, the system compares the new silhouette against a range of possible silhouettes that were reachable from the previous silhouette, and uses that to determine the likely location of the fold made and its type. The paper does not investigate the use cases for this detection as part of an input device.
FoldMe: Interacting with Double-sided Foldable Displays

Investigates possibilities afforded by folding displays
Klalilbeigi explore a very similar space to the one we are, but limited themselves more to exploring low-fidelity horizontal and vertical folds of a display. They come up with a variety of interaction principles that can be applied to designing applications for a foldable display. However, they do not explore the possibilities of non-quadrilateral or multi-dimensional shapes, and do not explore the possibilities of tangible interaction which arise when you can make more complex, high-fidelity, origami-like folds in the display.
Novel User Interaction Styles with Flexible / Rollable Screens,

Self contained device: Flexible, rollable screens
This paper investigates the possible technologies that could be used to implement flexible screens.The authors look ast sensors such as gyroscopes and accelerometers. The product they describe can only be rolled into different configurations whereas the aim of Projectagami is to be able to fold your device, just like origami. Similar to Projectagami, this paper by Samsung Research also looks at how different device configurations can be used as a tangible interface.
Tessella: interactive origami light,

Shape shifting interactions
The paper demonstrates an interactive light made from origami that transforms shape. This paper has interesting parallels to Projectagami as there is a discussion about how the form of the device implies its function. For example, our Book example suggests that you have to open it to see what is inside the book.

MEMS-Controlled Paper-Like Transmissive Flexible Display

Technology enabling future devices
A novel microelectromechanical-systems (MEMS)-controlled paper-like transmissive flexible display device was modeled by a combination of a cantilever with a flat plate and was realized by roll-to-roll printing process for the first time. This model provides predictions as well as improvement suggestions to both mechanical and electrical designs.
Tri-Foldable AMOLED displays

Foldable display
A folding screen type OLED display was developed (Fig. 1) to demonstrate the application of a flexible display. The display surface can be bent with a curvature radius of 4 mm. To protect an OLED against moisture, inorganic passivation layers are provided on the upper and lower sides of the flexible display. Using our transfer technology, dense passivation layers can be obtained. The measured water vapor transmission rate of the layer is 7 u 106 g/m2 day or less, which improves OLED reliability.

An enhanced user interface design with Auto-Adjusting Icon Placement on foldable devices

http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6974178
Research in area of HCI and flexible displays
Flexible electronics appear in the consumer, medical, and military sectors. Thanks to the development of flexible electronics, flexible touchscreens have been widely carried on in various devices, such as mobile phones, wearable devices and hand-held tablets. (..)

On the flexible touchscreens, when the displays are folded, some touch area around the folded line is not touchable in users' operation, and this is a critical research problem for the flexible touch screens. However, to our knowledge, little or no user interface research has solved this problem. To resolve this critical problem, in this study, we design a novel user interface, called the Auto-Adjusting Placement, which can dynamically adjust objects, such as icons, texts and pictures, on the flexible touch screens to avoid the area around the folded line and to keep the high availability/readability of the objects.

Projectagami Demo Preparation




Today, we finalised our demonstration in preparation for our demo tomorrow! We use the Wizard of Oz technique to demonstrate our proof of concept of a self contained device that can be folded with high fidelity.

Looking forward to presenting this tomorrow!
