Unlocking The Robotic Cleaner of Tomorrow
Apr 2019
Adapting your products to customer needs is critical, and robotic vacuum cleaners have made serious headway in recent years when it comes to improving the user experience. But challenges still exist: robots that get stuck on chair legs, lost in corners, or take inefficient routes, all of which lengthen cleaning times and drive up battery consumption (driving down user satisfaction).
Motion sensors play a key role in improving robotic vacuum cleaner performance. Read our Ebook, “Unlocking the Robotic Cleaner of Tomorrow” to learn:
  • The top challenges that persist in the robotic vacuum industry
  • A few key trends shaping the market
  • How to choose the right sensor set (to mag, or not to mag...?)
  • How sensor fusion ensures peak performance


Motion Sensors For Low-Latency 3D Audio Head Tracking
Mar 2019

3D audio can truly immerse a user in a new space. Sounds from a real-world source reach each ear at a different time, and your brain interprets these differences in time to determine directionality.

The World...At Your (Customers’) Fingertips: 8 New Use Cases for Handheld Motion Control
Feb 2019

Handheld motion control isn’t new. As a core feature for devices in the past, it was expensive to produce and was never able to fully blossom. But over the years, motion sensor technology has advanced by leaps and bounds, unlocking new uses.

The World Isn't Flat: Go Beyond Single-Axis Planar Navigation
Feb 2019

Robotic vacuum cleaners are all about simplifying lives by saving time. Cleaners that get lost or stuck in corners, miss spots on the floor or run out of battery before returning to their dock lead to dissatisfaction with your product. But innovations in sensor technology can enable robots to clean smarter and more effectively. And, multi-axis sensors are leading the charge.

Arm Cortex-M7 Processor in Sensor Fusion
Nov 2018

This paper sets out to explain the background of sensor fusion processing and to present to the reader the advances in device capability that the Cortex-M7 processor enables. As well as explaining the benefits of the Cortex–M7 architecture in sensor fusion.

Arm-Powered Sensor Fusion
Nov 2018

From game consoles to smart TV remote controls to, more recently, smartphones, sensor fusion has been used to create more intuitive and fun interactions for consumer electronics. Hillcrest has been a pioneer in this space for over a decade, developing proprietary signal processing techniques to transform human movement into high quality, application-ready motion information using MEMS inertial and magnetic sensors.

3D Mouse Cursor Control for Smart TV Applications
Oct 2013

This document explains the foundations of 3D mouse cursor control for Smart TV applications. More specifically, it describes the 4 most important considerations for cursor control:

– The development of the PC mouse and the optimization for GUI navigation

– Specific considerations of the air-mouse and the living room environment

– Absolute Pointing use cases

– Freespace optimizations for Smart TV applications

Pointing on TV: A Comparative Study of Touch vs. Motion
Oct 2013

As demand for Internet content on television increases, service providers and consumer electronics manufacturers need alternative technologies to the traditional up/down/left/right remote control in order to delight consumers with new interactive experiences on TV. This paper describes why pointing is the right solution for controlling the TV experience, and compares two technologies that enable pointing remote controls: touchpad and motion control. A series of studies compare these two methods of pointing for two common use-cases: navigation and casual gaming. Results show that pointing by motion is superior to pointing with touchpad for both use-cases.
