AirPincher

Kyeongeun Seo, Hyeonjoong Cho 

There are two kinds of mid-air hand gesture-aware techniques, wearable sensor-based and external-vision-based. The wearable sensor-based techniques cause cumbersomeness of wearing sensors every time and the external vision-based techniques incur performance dependence on distance between a user and a remote display.AirPincher is designed to overcome disadvantages of these two kinds of existing techniques. AirPincher allows a user to hold the device in one hand and to generate several delicate finger gestures. The gestures are captured by several sensors proximately embedded into AirPincher.

Visual Programming Language 

Park Eun Ji, Seo Kyeong Eun, Park Tae Gon, Sun Duk Han, Cho Hyeonjoong 

Industrial robots have been usually controlled using text-based programming languages provided by each manufacturer with its button-based TP(Teaching Pendent) terminal. Unfortunately, when we consider that people who manipulate TPs in manufacturing sites are mostly unskilled with no background knowledge about computer programming, these text-based programming languages using button-based interaction on manufacturing sites are too difficult for them to learn and use. In order to overcome the weaknesses of the text-based programming language, we propose a visual programming language that can be easily used on gesture-enabled devices. Especially, in our visual programming environment, each command is represented as a block and robots are controlled by stacking those blocks using drag-and-drop gestures, which is easily learnable even by beginners.
