Bevel or Not: Identifying the Potential of Bevels for Touch Input Accuracy on Ring Device

Smart rings can serve as a wearable platform for off-device control of nearby devices. However, their thin bands lead to a small touch surface on the ring, limiting touch input expressivity and accuracy. To address this, we investigate the effectiveness of ring shapes that use beveled surfaces in addition to the flat…

Improving Putting Accuracy with Electrical Muscle Stimulation Feedback Guided by Muscle Synergy Analysis

Muscle synergy analysis provides a method for quantifying differences in muscle use between expert and novice athletes. However, the practical applications of muscle synergy analysis with feedback remain underexplored. In this paper, we present a golf putting training system that utilizes electrical muscle stimulation…

Invisible Light Touch: Standing Balance Improvement by Mid-Air Haptic Feedback

Improving standing balance is critical for preventing falls and ensuring the well-being of older adults. In this paper, we present Invisible Light Touch (ILT), a mid-air haptic feedback application designed to improve standing balance by utilizing the light touch effect, a well-documented phenomenon in medical researc…

Estimating Attention Allocation by Electrodermal Activity

Electrodermal activity (EDA) represents changes in the electrical activity of the palmar skin and serves as an indicator of sympathetic nervous system activity. This paper presents a novel method for estimating attention allocation under divided attention conditions using only EDA data. Our approach involves the use o…

Learning Effects and Retention of Electrical Muscle Stimulation in Piano Playing

Electrical muscle stimulation (EMS)-based systems have been proposed to assist in the learning of motor skills for piano playing. However, learning effects and retention have not been thoroughly evaluated. To address this, we conducted two user studies to investigate the learning effects and retention of EMS for piano…

Assisting with Fingertip Force Control by Active Bio-Acoustic Sensing and Electrical Muscle Stimulation

Fingertip force control plays an important role in learning motor skills. Exoskeleton gloves have been developed to assist with fingertip force control, but having the equipment on the fingers interferes with finger motion control and tactile sensation. Thus, we present a system for assisting with voluntary fingertip…

Muscle Synergies Learning with Electrical Muscle Stimulation for Playing the Piano

When playing scales on the piano, playing all notes evenly is a basic technique to improve the quality of music. However, it is difficult for beginners to do this because they need to achieve appropriate muscle synergies of the forearm and shoulder muscles, i.e., pressing keys as well as sliding their hands sideways.…

Controlling Maximal Voluntary Contraction of the Upper Limb Muscles by Facial Electrical Stimulation

In this paper, we propose to use facial electrical stimulation to control maximal voluntary contraction (MVC) of the upper limbs. The method is based on a body mechanism in which the contraction of the masseter muscles enhances MVC of the limb muscles. Facial electrical stimulation is applied to the masseter muscles…
