Vestibular perception is useful to maintain heading direction and successful spatial navigation. In this study, we present a novel equipment capable of delivering both rotational and translational movements, namely the RT-Chair. The system comprises two motors and it is controlled by the user via MATLAB. To validate the measurability of vestibular perception with the RT-chair, we ran a threshold measurement experiment with healthy participants. Our results show thresholds comparable to previous literature, thus confirming the validity of the system to measure vestibular perception. Clinical relevance-This research presents a novel motion simulator to deliver combined or independent stimulation of the vestibular canals and otolith organs.

HighlightsWe developed a wearable platform (KiD) designed for tracking movements of children We establish the potential of KiD as stand-alone movement measurement platformWe demonstrate successful classification of different types of movements using KiD Accelerations collected using KiD compare well with those of optical MoCap systems

This work presents a simple integer-only instruction set architecture and microarchitecture derived from One Instruction Set Computers (OISCs) and embedding multiple execution modes (mOISC), capable of running at a reasonable performance level to enable basic usability in microcontroller applications. The purpose of mOISC is to enable simple data transfer tasks and run small programs while maintaining ultimate simplicity. We present the internal organization for a computer architecture including an 8 bit I/O register, and 64 kB central Random Access Memory (RAM), organized in two-bytes words. The processor can run code generated assuming an OISC or a Complex Instruction Set Computer (CISC) scheme (op-code based), depending on the programmer's demands and based on the initial setting of a register during start-up. To enable practical applications and demonstrate successful exploitation of mOISC in view of integration in a compiler back-end, we designed a custom Proof-of-Concept (PoC) software design toolchain based on LLVM and clang. Although not targeting all the features of commercial ISA, the toolchain is capable of compiling C code from LLVM intermediate representation or generating mOISC code translated from ARM, x86, RISC-V, and MIPS assembly. The toolchain also enables practical Value Change Dump (VCD) simulations output with graphical plots of the CPU state and associated symbols. A PoC microcontroller system has been synthesized in a low power Field Programmable Gate Array (FPGA) and verified in a basic wireless telemetry application including a Synchronous Peripheral Interface (SPI) RFM9x Long RAnge (LoRA) transceiver and a MAX30205 Inter Integrated Circuit (I 2 C) temperature sensor, using its 8 bit I/O port, with software bus interface implementation. mOISC occupies ∼6% of resources on a Cyclone 10LP FPGA, for 1397 Adaptive Look-Up Tables (ALUTs) and 461 dedicated logic registers. The measured dynamic current consumption of the complete FPGA board with synthesized mOISC is 12 mA at 100 MHz clock.
