AVGVST Guest Post: Technology from Neo Tokyo

This is a guest post by AVGVST creative agency. AVGVST are our good neighbours here in Nishizabu Tokyo, so we thought it is a good idea to ask them to create a few good-looking blog posts for us.

Teamwork

LP-RESEARCH provides answers to some of today’s hard engineering problems and questions. It is in the company’s essence to find those solutions and provide them to the people who need them most.

Find out more about the company and the people behind it in this interview with the LP-RESEARCH team.

Global Scale

We are in Germany, on one of the fastest highways on this planet – Die Autobahn. A silver limousine is cruising down the road, gentle and elegantly it cuts through traffic. Its driver wears augmented reality glasses projecting his distance to other cars, navigation information and nearby construction zones directly onto the road into the driver’s field of view.

Beijing China. A forklift is navigating autonomously through a warehouse to organize the stock of an international trading company. Following its pre-programmed routine, the forklift silently moves from A to B, B to C, repeat, effortlessly picking up and delivering palettes loaded with goods to be shipped.

Thousands of miles away, an employee of a Swiss chocolate factory is packing pralines into heart-shaped boxes. His movements are efficient, following a dynamically calculated pattern optimized to maximize productivity, while at the same time helping the employee to keep a healthy posture and minimize the strain on his joints.

From the warehouse in China over chocolate made in Switzerland to cruising on the German Autobahn, there is one thing that connects all these locations: A technology company from Tokyo – Life Performance Research Inc.

Solutions to Hard Problems

The core of LP-RESEARCH’s business and the starting point on many of their journeys to finding a solution to a hard problem relies on their advanced sensing and measurement technology. LP-RESEARCH’s product, the Life Performance Motion Sensor (LPMS) algorithmically fuses together information from a gyroscope, accelerometer and other sensors.

Mathematically “glued” together, these data streams produce a result that is in its accuracy and responsiveness superior to the information gathered from a singular source. This type of sensor fusion represents the focus and core knowledge of LP-RESEARCH’s developments and is applied in all variations of the company’s products and services.

iOS Support for LPMS-B2

LPMS-B2, besides Bluetooth classic, also supports Bluetooth 4 / Bluetooth Low Energy. This allows us to connect the sensor to Apple mobile devices such as the iPad, iPhone or the Apple watch. We recently have created a library that enables development of applications supporting LPMS-B2 on these devices.

The library can be accessed via our open source repository.

The repository contains a skeleton application that shows usage of the most basic parts of the library. The library itself is contained in the following files:

LpmsB2.m
LpmsB2.h
LpmsBData.m
LpmsBData.h

A sensor object is initialized and connected using the follwoing code:

#import "LpmsB2.h"
#import "LpmsBData.h"
..
CBPeripheral *peripheral;
CBCentralManager *centralManager;
..
LpmsB2 *myLpmsB2;
myLpmsB2 = [[LpmsB2 alloc] init];
[myLpmsB2 connect:centralManager Address:peripheral];

More coming soon..

LPVR Manual & VIVE Pro Holder Prototype

LPVR Quick Start Guide

We have written a quick start guide for the LP VR system. The guide describes the assembly of the VIVE marker holder and the installation/usage of the LPVR SteamVR driver. The guide at the moment doesn’t contain information about the new VIVE Pro holder, but this will be added later.

Download the guide from here: LpvrGettingStarted20180402.pdf

VIVE Pro Sensor Holder

We have been working on the development of a optical marker/sensor holder for the VIVE Pro for a few weeks. It is not completely finished yet, but below is a photo of a prototype.

LP Sensors at Bandai Namco VR Zone: Ghost in the Shell VR Experience

Shinjuku VR Zone logo

Recently Bandai Namco has opened a VR entertainment center in central Tokyo, titled the VR Zone. One part of VR Zone is a revolutionary new free-roaming arcade experience built on the theme of anime classic Ghost in the Shell.

LP-RESEARCH has provided IMU technology that allows the system to operate with the HTC VIVE. The result is a uniquely fascinating and fun arcade experience. Our team was very happy to test the experience before the official openning of VR Zone and greatly enjoyed it. VR at its finest, highly recommended!

Large-scale VR Application Case: the Holodeck Control Center

The AUDI Holodeck

LPVR interaction

Our large-scale VR solution allows any SteamVR-based (e.g. Unity, Unreal, VRED) Virtual Reality software to seamlessly use the HTC VIVE headset together with most large-room tracking systems available on the market (OptiTrack, Vicon, ART). It enables easy configuration and fits into the SteamVR framework, minimizing the effort needed to port applications to large rooms.

One of our first users, Lightshape, have recently released a video showing what they built with our technology.  They call it the Holodeck Control Center, an application which creates multi-user collaborative VR spaces. In it users can communicate and see the same scene whether they are the same real room or in different locations. The installation showcased in the video is used by German car maker Audi to study cars that haven’t been built yet.

Our technology is essential in order to get the best VR experience possible on the 15m × 15m of the main VR surface, combining optical tracking data and IMU measurements to provide precise and responsive positioning of the headsets.  Please have a look at Lightshape’s video below.

Ready for the HTC Vive Pro

In the near future, this installation will be updated to the HTC Vive Pro which our software already supports. The increased pixel density of this successor of the HTC Vive will make the scenes look even more realistic. The resolution is high enough to actually read the various panels once you are in the drivers seat! Besides that, we are also busy studying applications of the front-facing cameras of the Vive Pro in order to improve multi-user interaction.
