Interface Design for D-TV Browsing & Navigation System
Television / Computer convergence is technologically complete, which makes the TV industry hard for no-technical people to understand. And the viewers are still satisfied with ‘good old fashioned’ linear video for TV. To design an efficient way of massive video content browsing system, we have done background and user research. By analysing the results, we extract key design concepts.
To make a design concept, I made a different type of design and semi-prototype with a few kinds of digital sensor. And finally, we think out a card deck metaphor for navigation. This is ordered by time and channel controlling by vector pad which is a capacitance type force sensor. This prototype was Invited by Microsoft uxtv 08.
Simulators for LED use and arrangement
on the exterior of buildings
These days, a lot of buildings are decorated with LED. A few month ago, one of the construction companies in South Korea asked me that how to estimate the amount of LED they would need for the outside of a particular building. The company wanted to cover one whole surface of the structure with LED panelling. However, they have concerns because their budget is limited. Therefore, I decided to simulate the whole structure to test a different type of LED arrangement and estimate the amount of LED needed. In this project, I focused on how to immediately change the arrangement of LED and how to realistically show the structure in this simulation to make a final conclusion. Accordingly, I made a virtual space simulation to demonstrate the LED details on the structure and evaluate the costs much as an architect would do.
Although there were a lot of problems to solve, the most important thing to simulate realistically is a diffusion of light in the graphics. Therefore, I added a variable which means a ratio of diffused level. This ratio affects a relation of camera distance and diffused LED level wheeling a mouse wheel. So I can actually change diffused lights level immediately. After that, I observed a real LED panel to decide the correct ratio. I also tried to solve several of the problems on this simulator such as how to spread colours from bitmap images or how to set and move a camera angle as human sight does or how can I make a real-time 3D mapping texture.
It was meaningful project for me because I could also think about how to relate digital media to real world. I realised that budgets, engineering, and working processes are also very important.
Seoul Bingo is a simple game that incorporates Bingo game with treasure hunt game. In this game, players can find real images of Seoul where people lives and experiences. With GPS and mobile technology, it is possible to integrate real world with virtual world. The concept of this game is to allow users to enjoy real Seoul tour while they play a Bingo game. This concept was rewarded UX conference 2009 Gold Prize.
