His work primarily focuses on improving the functionality and efficiency of haptic devices.

Latest Patents

One of Halagur's latest patents is related to the "Braking control of haptic feedback device." This invention involves a controller that obtains a back electromotive force (BEMF) signal associated with a haptic feedback component. The BEMF signal is generated by the movement of the haptic feedback component. The controller determines a time length for the BEMF signal to cross an amplitude-based window and, based on this time length, calculates a braking amplitude for a control signal. This control signal is designed to reduce the energy level of the haptic feedback component, thereby enhancing its performance.

Another significant patent is focused on "Haptics audible noise reduction." This innovative technique proposes methods to design and generate haptic waveforms that reduce or eliminate audible noises produced by a haptic actuator during operation. The haptic controller composes a voltage waveform at a resonant frequency of the actuator and generates a corresponding control signal. By including a ramp-down portion in the voltage waveform, the current flowing within the actuator is gradually reduced before entering a high impedance state, effectively minimizing audible noise.
