Visual Support System Considering Privacy Protection by Using the Line Drawing Video Image

This paper proposes a system that automatically deforms the original video images into line drawing expression transmitted in both directions so as to achieve two goals: easing the concerns of users privacy and ensuring good enough support by visual channel. We examine the effect of line drawing video for support system on the effectiveness and impression of privacy on a collaboration between a novice user and an operator. As a result, it became clear that concern of the user on privacy or security are greatly reduced by using a line drawing image, and there was no significant difference on efficiency with an original image and a line drawing image.
