Arata Jingu | 神宮 亜良太

I am a first-year Ph.D. student at Human Computer Interaction Lab at Saarland University, advised by Prof. Dr. Jürgen Steimle.
My interests are: (1) leveraging the human-body mechanism to interact with computers, (2) exploring novel interactions with a low-burden device, and (3) expanding the possibilities of future entertainment.

Visions

Lips as Interface
My three papers (CHI'23, UIST'21, WHC'21) explored "Lips as Interface". Lips have high potential as I/O interfaces: dexterous, inherent in humans, sensitive to touch, electrically conductive, valley-shaped capable of converging ultrasonic waves, close to other intraoral parts, and easy to access from the outside environment. Just as our fingers have become a touch I/O interface in today's touchscreens, we might witness how our lips EVOLVE in the following decades.

LipNotif: Use of Lips as a Non-Contact Tactile Notification Interface Based on Ultrasonic Tactile Presentation

In Proc. UIST'21 (full paper, acceptance rate: 25.9%)
We propose LipNotif, a non-contact tactile notification system that uses airborne ultrasound tactile presentation to lips. This work is based on the lips' inherent structures/properties in mid-air ultrasound haptics. LipNotif allows users to receive tactile notifications using lips without sacrificing busy eyes/ears/hands or wearing bulky devices.

Tactile Perception Characteristics of Lips Stimulated by Airborne Ultrasound
Arata Jingu, Masahiro Fujiwara, Yasutoshi Makino, Hiroyuki Shinoda
In Proc. WHC'21 (full paper, acceptance rate: 40%)
We investigated the tactile perception characteristics of lips in mid-air ultrasound haptics. The lowest tactile thresholds of the lips were achieved at the valley-shaped area of the lips in terms of location, lateral modulation with periodic circular trajectories (LMc) in terms of modulation type, and 40 Hz in terms of modulation frequency.

Dynamic Iris Authentication by High-speed Gaze and Focus Control

In Proc. SII'21 (short paper)
We propose a dynamic iris authentication system using high-speed gaze and focus control by high-speed image processing. We control high-speed rotational mirrors and liquid-based variable focus lens by triangulation with a wide-angle camera. We also control the liquid lens with additive modulation of a sine wave to get the most focused iris image.
