“…Thus, each joint motion depends only on the motor motion corresponding to the joint. The parallel rotational mechanism can be considered as a linearized version of linkage-based mechanisms [10- 13,20,21] under the assumption that the transmission through the second joint is rigid enough.…”

“…Certain non-commercialized haptic interfaces have targeted high force capabilities, ROMs, and high backdrivability [15,20,21]. One hybrid actuation mechanism separated high-and low-frequency force generation using different sizes of actuators for the base part and distal side [15].…”

“…Thus, it had a high overshoot and long settling time. Barnaby et al developed a haptic interface with backdrivable actuators, timing belt reductions, and a four-bar linkage mechanism [21]. While the system showed high backdrivabilty, the force was as low as those of commercial haptic interfaces.…”

This paper presents a haptic interface with modular linear actuators that addresses the limitations of conventional devices based on rotary joints. The proposed haptic interface is composed of parallel linear actuators that provide high backdrivability and small inertia. The performance of the haptic interface is compared to those of conventional mechanisms in terms of force capability, reflected inertia, and structural stiffness. High stiffness, large range of motion, and high force capability, which are in trade-off relationships in traditional haptic interfaces, are achieved. The device can apply up to 83 N continuously, i.e., three-fold more than most haptic devices. The theoretical minimum haptic force density and stiffness of the proposed mechanism are 1.3 to 1.9 and 37 times those of the conventional mechanisms under similar conditions, respectively. The system is scalable because the structural stiffness depends on only the timing belt stiffness, whereas that of conventional haptic interfaces is inversely proportional to the cube of the structural length. The modular actuator enables changes in the degrees of freedom (DOFs) for different applications. The proposed haptic interface was tested through an interaction experiment in a virtual environment with virtual walls.

“…Some exosuits [36,37] use a similar cable/clutch design, integrating the bowden cables on the suit or soft fabric and creating similar motion constraints via passive actuation. Wearables with more advanced control designs [38] include brushless motor actuators attached to the body attachment, allowing for more realistic force feedback and active effects. The controller presented in this paper aims to provide feedback for continuous motion as well as impact by combining a flywheel that can rotate in 2 degrees of freedom and a brake mechanism.…”

Most haptic actuators available on the market today can generate only a single modality of stimuli. This ultimately limits the capacity of a kinaesthetic haptic controller to deliver more expressive feedback, requiring a haptic controller to integrate multiple actuators to generate complex haptic stimuli, with a corresponding complexity of construction and control. To address this, we designed a haptic controller to deliver several modalities of kinaesthetic haptic feedback using a single actuator: a flywheel, the orientation of which is controlled by two gimbals capable of rotating over 360 degrees, in combination with a flywheel brake. This enables the controller to generate multiple haptic feedback modalities, such as torque feedback, impact simulation, low-frequency high-amplitude vibrations, inertial effects (the sensation of momentum), and complex haptic output effects such as the experience of vortex-like forces (whirl effects). By combining these diverse haptic effects, the controller enriches the haptic dimension of VR environments. This paper presents the device’s design, implementation, and characterization, and proposes potential applications for future work.

Human–computer interaction scholars are increasingly touching on topics relatedto politics or democracy. As these concepts are ambiguous, an examination ofconcepts’ invoked meanings aids in the self-reflection of our research efforts. Weconduct a thematic analysis of all papers with the word ‘politics’ in abstract,title or keywords (n=378) and likewise 152 papers with the word ‘democracy.’We observe that these words are increasingly being used in human-computerinteraction, both in absolute and relative terms. At the same time, we show thatresearchers invoke these words with diverse levels of analysis in mind: the earlyresearch focused on mezzo-level (i.e., small groups), but more recently the workhas begun to include macro-level analysis (i.e., society and politics as played inthe public sphere). After the increasing focus on the macro-level, we see a tran-sition towards more normative and activist research, in some areas it replacesobservational and empirical research. These differences indicate semantic differ-ences, which – in the worst case – may limit scientific progress. We bring thesedifferences visible to help in further exchanges of ideas and human–computerinteraction community to explore how it orients itself to politics and democracy.
