Design notes part 1: Digital impacting Physical<\/h3>\n\n\n\n

When building a mixed-reality setup, the digital components impose some limits on the physical aspects. Ideally, you would like to move all components to the realm (digital\/physical) in which they are the easiest and\/or most effective to implement, but due to the restrictions of technologies this is not always possible. Here are some examples of how the technologies we used impacted our design choices.<\/p>\n\n\n\n

Pepper\u2019s Ghost screens<\/h3>\n\n\n\n

The technology has to work effectively in the box you design. As the Pepper\u2019s Ghost effect<\/a> works with a 45-degree-angled screen, this screen needs to fit the apartment and its furniture. Furthermore, the effect works best when viewed from the front. Although it has a reasonable viewing angle, it will not work at all when viewed from the sides as you will look onto the edge of the screen. This way, the box needs to be built \u2018peep box style\u2019, with only visibility from the direct front.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Most practical, the size of the box is determined by the size of the screen you use for projecting the Pepper\u2019s Ghost. In our case we went for a 15,6\u201c screen, which meant the effective width of the play area inside the box could be no wider than 34,4 cm.<\/p>\n\n\n\n

Lighting<\/h3>\n\n\n\n

During development we found that lighting can be done both through the digital layer and the physical layer. Atmospheric lighting can be generated by the laptop screen<\/a>, but also by LEDs in the box. However, too many lights within the box will wash out the visibility of the digital layer.<\/p>\n\n\n\n
