Social Digital Cyborgs: The Collaborative Design Process of the JIZAI ARMS

Half a century since the concept of a cyborg was introduced, digital cyborgs, enabled by the spread of wearable robotics, are the focus of much research in recent times. We introduce JIZAI ARMS, a supernumerary robotic limb system consisting of a wearable base unit with six terminals and detachable robot arms controll…

Affective Profile Pictures: Exploring the Effects of Changing Facial Expressions in Profile Pictures on Text-Based Communication

When receiving text messages from unacquainted colleagues in fully remote workplaces, insufficient mutual understanding and limited social cues can lead people to misinterpret the tone of the message and further influence their impression of remote colleagues. Emojis have been commonly used for supporting expressive c…

MetamorphX: An Ungrounded 3-DoF Moment Display that Changes its Physical Properties through Rotational Impedance Control

Humans can estimate the properties of wielded objects (e.g., inertia and viscosity) using the force applied to the hand. We focused on this mechanism and aimed to represent the properties of wielded objects by dynamically changing the force applied to the hand. We propose MetamorphX, which uses control moment gyros…

Teardrop Glasses: Pseudo Tears Induce Sadness in You and Those Around You

Emotional contagion is a phenomenon in which one's emotions are transmitted among individuals unconsciously by observing others' emotional expressions. In this paper, we propose a method for mediating people's emotions by triggering emotional contagion through artificial bodily changes such as pseudo tears. We focus…

PoCoPo: Handheld Pin-based Shape Display for Haptic Rendering in Virtual Reality

We introduce PoCoPo, the first handheld pin-based shape display that can render various 2.5D shapes in hand in realtime. We designed the display small enough for a user to hold it in hand and carry it around, thereby enhancing the haptic experiences in a virtual environment. PoCoPo has 18 motor-driven pins on both sid…

PaCaPa: A Handheld VR Device for Rendering Size, Shape, and Stiffness of Virtual Objects in Tool-based Interactions

We present PaCaPa, a handheld device that renders haptics on a user's palm when the user interacts with virtual objects using virtual tools such as a stick. PaCaPa is a cuboid device with two wings that open and close. As the user's stick makes contact with a virtual object, the wings open by a specific degree to dyna…

Transcalibur: A Weight Shifting Virtual Reality Controller for 2D Shape Rendering based on Computational Perception Model

Humans can estimate the shape of a wielded object through the illusory feeling of the mass properties of the object obtained using their hands. Even though the shape of hand-held objects influences immersion and realism in virtual reality (VR), it is difficult to design VR controllers for rendering desired shapes acco…
