A system for controlling ARGB LED (addressable full-color LED) tapes and LED matrices such as WS2812B from Windows and other devices.
The system can also be used from Unity, Unreal, etc., and operates at high speed and stability at 60 fps. The system has also been adopted by arcade game machine manufacturers for their sound games.
We are designing the hardware from draft to prototype and developing the software up to mass production.
June 2021 – July 2021
Developed middleware to analyze the center of gravity, stride length, and gait habits of a pedestrian by analyzing the output of a new type of pressure sensor at a national research institute. In July 2021, the device applying this software was exhibited at an exhibition organized by the Ministry of Education, Culture, Sports, Science and Technology.
Produced image analysis software by full scratch when OpenCV could not be used in the past. This experience helped us to respond in the short term.
Also analyzed the new pressure sensor (DLL) with permission, as there was a lack of documentation on it.
January 2017 – present
Have developed specialized configuration tasks and tools for the 24-hour unattended operation of Windows 10, like a games machine or a vending machine.
For example…
To prevent the file system from being corrupted even if the power supply is suddenly unplugged.
To ensure that updates and dialogs do not occur on their own.
Automatic Windows activation during mass production
Ignore keyboards and other devices plugged into the USB port.
Encrypts and installs applications (copy protection)
Update and maintenance functions.
Design and development of security devices such as USB dongles (which must be inserted to boot).
2012 – 2014
To realize a new way of playing with toys and arcade game machines through bidirectional communication using a wireless LAN.
Regarding the communication system, 1 hardware person, and 1 software person were me. (There seemed to be a lot of people in the game development itself)
Conception, design, implementation, and testing of the communication system.
Providing operational DLLs and sample programs to the game production side.
The challenge was to devise a robust connection and data transfer method, even with limited equipment and a poor installation environment.
- The electronic toy side has a small amount of RAM and only supports UDP with 11.b/g.
- The game console (Windows) side could be crowded with players, who were an obstacle to radio interference.
- Multiple game consoles were deployed in the same location (beyond the number of channels of the wireless LAN) and the toy had to be able to communicate with approximately any of the consoles.
- The location of the game machines could not be chosen, so there was a risk of interference from other business WLANs.
- There was a risk of microwave ovens interfering with the wireless LAN if the installation location was close to a food court.
- Basic protocols such as DHCP were also unstable due to the unstable wireless LAN.
- The wireless LAN parent unit was installed in a game machine, but it was necessary to automate the setup of the parent unit during mass production at the factory.
Developed a robust network structure and protocol using UDP and were able to construct a system that can be mass-produced and operate stably in the field.
Business Outcomes
Achieved Inter-device communication without any restrictions on the installation location or the number of players.
The unit won the 2012 Toy Award.
January 2009 – present
Created an Encoder, decoder, and publishing system for new 2D symbols at the request of a major publisher.
The system uses Adobe Illustrator scripts to enable automatic, high-volume publishing.
Also developed a decoder (image recognition) for environments with poor shooting conditions.
The basic specifications were provided by the customer, and we developed the detailed specifications and implementation.
It is probably available in large quantities in the world.
July 1999 – present
Develop systems for devices built into arcade game machines.
Examples of built-in devices handled include:
Have designed and implemented software for devices built into game consoles, and created sample software for use by higher-ups in C++ and Unity.
Also offer mass production support, including the development of software to absorb mechanical behavior with manufacturing variations.
Debugging is also available, including the collection and analysis of recordings and error logs, and the automation of reproduction.
All these products have been featured in various media and have been placed in the games section of shopping malls and other places, where they have been well received.
January 1999 – present
Took charge of the design, development, and maintenance of a customer management system for a game center. We developed the basic part of the system, and the subcontractor continued the development.
We are proud that our system that automatically awards points to members using a “card reader unit and sales monitoring board” retrofitted to a medal machine has been a driving force in IoT since 1999.
April 1993 – present
Since my previous job, I have been the main programmer for game machines and other equipment installed in game arcades and daycare facilities for the elderly.
In addition to software for prototyping and mass production, we also develop various types of software to improve factory productivity.
2017 – 2018
Developed software for a neck-mounted toy that acts at a designated location in an amusement park in an environment where radio waves cannot be used, and for a fixed device and a transmitter terminal carried by the crew that sends data to the toy via infrared light.
Problem Solved:
No tampering with a home appliance remote control, etc.
Considering the effects of outdoor sunlight, we devised a robust transmission method and transmission format.
Business Outcome
Meeting the customer’s requirements, the product was produced in large quantities.
