Detectability and Perceptual Consequences of Delayed Feedback in a Vibrotactile Texture Display
Found in: IEEE Transactions on Haptics
By Shogo Okamoto, Masashi Konyo, Satoshi Saga, Satoshi Tadokoro
Issue Date:April 2009
pp. 73-84
This study estimated the maximum allowable system latency for haptic displays that produce tactile stimuli in response to the hand movements of users. In Experiment 1, two types of detection thresholds were estimated for the time delay of stimuli through p...
Precise Shape Reconstruction by Active Pattern in Total-Internal-Reflection-Based Tactile Sensor
Found in: IEEE Transactions on Haptics
By Satoshi Saga,Ryosuke Taira,Koichiro Deguchi
Issue Date:January 2014
pp. 67-77
We are developing a total-internal-reflection-based tactile sensor in which the shape is reconstructed using an optical reflection. This sensor consists of silicone rubber, an image pattern, and a camera. It reconstructs the shape of the sensor surface fro...
Feel through window: simultaneous geometry and texture display based on lateral force
Found in: SIGGRAPH Asia 2012 Emerging Technologies (SA '12)
By Ramesh Raskar, Satoshi Saga
Issue Date:November 2012
pp. 1-3
Touching through a screen to a displayed object has been one of a goal of human interface. Several researchers employ vibrations in order to display texture information. However no systems realize to display geometrical shapes and textures. In this researc...
Fibratus tactile sensor using reflection on an optical lever
Found in: ACM SIGGRAPH 2007 emerging technologies (SIGGRAPH '07)
By Naoki Kawakami, Satoshi Saga, Shinobu Kuroki, Susumu Tachi
Issue Date:August 2007
pp. 3-es
Among several tactile sensors in use currently, none can evaluate the sense of gentle touch. We have developed a fibratus tactile sensor that utilizes the property of reflection. This sensor enables to evaluate the sense of gentle touch. We propose a new i...
