US 2018/0082482 A1 · EP 3,488,315 B1 (granted 2021)

Display system having world and user sensors

Apple Inc. · Published March 22, 2018 · with Ricardo Motta, Brett Miller, Tobias Rick

The sensing behind passthrough AR. World-facing and user-facing sensors unified in one display system — the architecture that lets a headset see the room and the wearer at once.

US 2019/0221044 A1

Display system having sensors

Apple Inc. · Published July 18, 2019

Sensors living inside the screen. Integrating cameras and sensors into the display stack itself — the display stops being just an output and becomes an input.

US 10,817,594 B2

Wearable electronic device having a light field camera usable to perform bioauthentication from a dorsal side of a forearm near a wrist

Apple Inc. · Granted October 27, 2020 · 51 Scholar citations

Your wrist is the password. A light-field camera on a wearable that authenticates from the dorsal forearm — biometrics with no fingerprint sensor and nothing to touch.

US 10,657,957 B2

Light field capture

Apple Inc. · Granted May 19, 2020

The whole light field, in one shot. Captures ray direction as well as intensity — the raw material for refocus-after-capture and single-shot depth.

US 11,550,408 B1

Electronic device with optical sensor for sampling surfaces

Apple Inc. · Granted January 10, 2023

A stylus that truly sees color. Multi-channel optical sensing samples real-world surfaces — point at anything and capture its exact color, not an approximation.

WO 2024/238704 A1 · US 2024/0385454 A1

Head mountable display

Apple Inc. · Published November 21, 2024 · Vision Products Group era

Building the headset, piece by piece. Head-mounted display systems from the founding years of the Vision Products Group.

US 2025/0181155 A1

Camera-less eye tracking system

Apple Inc. · Published June 5, 2025

Gaze tracking with no camera. The sensor disappears entirely — eye tracking that leaves only the signal.

WO 2026/072497 A1

Efficient eye imaging system for near-eye displays with integrated photodiodes

Apple Inc. · Published April 2, 2026

The display becomes the sensor. Photodiodes woven into the screen image the eye from inside it — sensing without a visible sensor.

WO 2016/097470 A1 · US 2016/0173869 A1

Multi-camera system consisting of variably calibrated cameras

Nokia Technologies Oy · Priority December 15, 2014 · with Ting-Chun Wang

Bokeh before Portrait mode. A main high-quality camera paired with auxiliary stereo cameras producing depth for defocus effects — filed two years before the iPhone 7 Plus made computational bokeh mainstream.

US 10,574,905 B2 · US 10,089,740 · WO 2015/134996 A1

System and methods for depth regularization and semiautomatic interactive matting using RGB-D images

Pelican Imaging / Fotonation · US granted 2018 & 2020
First-listed inventor

Making light-field depth trustworthy. Depth regularization that cleaned up noisy light-field depth — the foundation of the startup’s product demos (shown to Apple and Amazon, in Manohar’s account).

US 9,898,856 (2018) · US 10,540,806 B2 · WO 2015/048694 A2

Systems and methods for depth-assisted perspective distortion correction

Pelican Imaging / Fotonation · US granted 2018 & 2020 · 183 Scholar citations

His most-cited work. Uses depth to undo wide-angle perspective distortion — the reason faces stop looking warped at the edge of the frame.

US 9,170,580 B2

Determining trajectories of redundant actuators jointly tracking reference trajectory

Mitsubishi Electric Research Laboratories · Granted October 27, 2015

The control theory under the drones. Optimal trajectories for redundant actuators — from his Mitsubishi research-lab years, feeding the aerial-robotics work.

US 2012/0068927 A1 · GB 2,434,227 B (granted 2010)

Computer input device enabling three degrees of freedom and related input and feedback methods

With T. Poston · US filed 2007 · UK granted December 15, 2010 · 162 Scholar citations

His earliest invention on record. Three degrees of freedom in a single input device — and his second most-cited invention.

Research papers

The math behind the bets.

From MIT aerial robotics to computational cameras — each paper with the key idea it contributed and why it mattered.

Depth from semi-calibrated stereo and defocus

201625 citations

Two depth cues are better than one. Fuses stereo disparity with defocus blur — depth that holds up exactly where each cue alone fails.

Computational rim illumination with aerial robots

201424 citations

Drones as studio lights. Autonomous quadrotors that position themselves around a subject for perfect photographic rim lighting — robotics in service of the image.

Controlled manipulation with multiple quadrotors

201125 citations

Aerial robotics as a crew, not a solo act. Teams of quadrotors cooperating to carry and manipulate objects — coordination as a control problem.

A robust environment for simulation and testing of adaptive control for mini-UAVs

200925 citations

The flight simulator the lab trusted. A testbed for proving adaptive controllers in simulation before risking real hardware — infrastructure as research.

DC motor damping: a strategy to increase passive stiffness of haptic devices

200826 citations

Stiffer virtual walls, calmer motors. Damping the motor instead of fighting it — haptic devices that feel more solid with less energy.

Rendering stiffer walls: a hybrid haptic system using continuous and discrete time feedback

200711 citations

Touch you can believe. Hybrid continuous–discrete control that renders a virtual wall as genuinely solid — the haptics behind believable contact.

Visibility volumes for interactive path optimization

200811 citations

Planning through what can be seen. Treats visibility as a first-class citizen in motion planning — paths optimized inside the volume of the observable.

Dynamic modeling and control of a flexible four-rotor UAV

20107 citations

A bending drone doesn’t fly like a rigid one. Models flexibility in the airframe itself — control that accounts for the wobble instead of ignoring it.
