Technology demonstration

A technology demonstration is a prototype, rough example or an otherwise incomplete version of a product, put together with the primary purpose of showcasing the idea, performance, method or the features of the product. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach.

Computer technology demonstrations should not be confused with demoscene-based demos, which, although often demonstrating new software techniques, are regarded as a stand-alone form of computer art.


Computers and gaming

Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development.

  • Computer game developers use "tech demos" to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing. Short segments using finished game engines may be presented as game demos. Critics are also fond of calling certain complete games technology demos, due to the emphasis of the designers solely on the game's technology, severely lacking content in the process. id Software in particular has garnered its share of such criticism.
  • Graphics cards manufacturers use tech demos to showcase the performance of their cards even before there are any games that can deliver that performance or before the product is ready to be used outside of the development labs. In November 2002, NVIDIA started the practice of featuring realistic female characters in graphics card technology demos, by releasing Dawn for its GeForce FX card. The demo featured a scantily clad forest fairy with semi-realistic short hair and beautiful wings. Later NVIDIA followed with similar, new demos and ATI Technologies joined the race.
  • Being by nature much less complex than complete games (that have to include dynamic physics modelling, audio engines, etc.), technology demos for graphics can deliver substantially better image quality, making the general look of games lag several years behind video card technology demos. For example, the PlayStation 2 demos Namco Girl (a lifelike female character from Ridge Racer winking flirtatiously at viewers) and old man used all the processing power to produce a high-quality single character model, in a static environment. Xbox trailers also showed Raven, a buff woman and her robot, showing off martial art moves.

Computer technology demos should not be confused with demoscene-based demos, which, although often demonstrating new software techniques, are regarded as a stand-alone form of computer art.

Google Tech Demo

Demo Slam, a website from Google Inc., as launched with the slogan "Bring your creativity. Bring your tech. Just bring it in general, fool! Demo Slam is here!", is a large collection of technology demonstrations uploaded by users, and some of the Google executives as well, which will go to the 'Contender'

Sales engineering technology demonstration

Sales Engineering staff, often bearing the title Sales Engineer or Presales Consultant, will prepare technoloy demonstrations for business meetings or seminars to show capabilities of business products. This can include both software and hardware products, and can show multiple products integrating together. Usually a demonstration is less than a Proof of concept, but can come some of the way to showing how a business project may be justified. Large companies with tens or hundreds of Sales Engineers will often have a team who specialize in the production of demonstration systems and plans.


Occasionally, technology demonstrations prove to be rigged or even completely fake. For example, an empty case with blinking LEDs can be presented as the product, a demonstration of Internet Quality of Service software can be done on a LAN with manually regulated traffic, and pre-rendered videos or pictures with notably higher-quality models can be presented as actual game footage.

  • Deployment
  • Game demo. A game demo is usually distinguished from the full game not by being unfinished or untested, but by deliberately including only a portion of the full game's content (released to advertise the game and prove its quality to prospective players).
  • Research and development
