Impressions: Project Natal - Ricochet

If there was something that kept our heart from leaping duringMicrosoft’s admittedly impressive (lifestyle video aside) onstageunveiling of Project Natal, it was our last experience with acamera-enabled Microsoft game, the limp You’re In The Movies.

We mention our fears during our chat with Microsoft’s Don Mattrick,and he promises that the system isn’t too good to be true beforeliterally pulling us into a nearby meeting room to take part in a fewgames of Project Natal’s Ricochet prototype with the project’s creative director, Kudo Tsunoda.
   
Onwalking into the room, it’s immediately obvious that the system picksup Tsunoda’s body movements accurately with its stock but evenlighting. And, challenged by Mattrick, Tsunoda dims the lights to thelevel of a dark but not pitch-black room, and returns to playing Ricochet with no drop in precision.

A topic only touched upon during Microsoft’s press briefing, Tsunodaexplains that this was possible due to the way in which Project Natalanalyses your body to create your “skeleton” which it can thenaccurately follow, even if your arm or leg moves out of the camera’sview. The software can predict the placement of the limb based on thepositioning of the rest of the skeleton.

Of course, the proof is in the playing, and it isn’t until we stepinto the camera’s view that it starts to make sense. On beginning, thesystem takes 2-3 seconds to read your body shape, and we see our avatarreadjusting its height, since we’re several inches shorter thanTsunoda. And then, as much as this might sound like hyperbole, everysingle movement, however small, Natal picks up, from a scratch of thenose to a small hop forward or backwards.

Ricochet itself, a simple 3D physics-enabled block-breaking game that reminds of the Dreamcast’s Cosmic Smash,is an effective demonstration of some of Project Natal’s capabilities.That said, our initial difficulties betray the separation that stillremains between player and game. It’s hard to sense where the ballwould exist in the real world, making it a challenge to reach out intoreal space in order to hit a virtual one. Moreover, once we manage toget it bouncing around, our reactions tend to lag a split second afterthe ball’s out of our reach.

So, while we have no qualms in stating that Project Natal readsmovement supremely accurately, the issue of navigating a 3D space on a2D screen remains an issue. Accordingly, Ricochet the game is much more about trying to deal with keeping a vast quantity of balls in play via quick, expansive movements.

With Ricochet currently a tech demo, it would ultimately be foolishto assume that Project Natal’s future will entirely consist of similarmini-game experiences – that would surely squander the breadth of theprecision the system offers. But if Ricochet proves anything, it’s the bottom line: is Natal is for real? The answer to that is, definitively, yes.

少数报告要来了么

请问Cosmic Smash是啥？

有可能真如jl在一发布会中所说1%的价钱实现专用设备80%的特性~~
甚至可能是比1%更低~

神了

期待插空气活塞游戏出现

没看到那是斜体的么，那是指DC上的某个游戏。

本来类似的技术在CES 2008上就有很成熟的展示：

不妨看一下后来被微软收购的3DV Systems的 Zcam

是的 有质疑才有进步

神机的龟头棒怎么还不让试玩呢？

一些索饭的选择性失明技能早都练到极致了
这种消息必然被自动屏蔽

我们向微软的Don Mattrick提及对于Natal计划的疑虑，而在拉我们进入附近的会议室参与Natal计划创意总监Kudo Tsunoda所展示的Ricochet原形技术demo前，Mattrick承诺Natal绝不是一项太美好以致于无法实现的计划。

一走进会议室，我们看到Natal系统精确追踪到Tsunoda身体的运动。针对Mattrick提出的要求，Tsunoda将室内灯光调至灰暗但不至于完全漆黑的程度后，游玩Ricochet仍不会有精确度上的下降。

Tsunoda解释了Natal系统何以分析玩家的身体来创建一套可以精确追踪位移的「骨架定位点」系统。即使你的四肢移出摄影机的视野之外，软体还能以其他骨架定位点来预测肢体的位移幅度。

实际试玩无疑是证明Natal能力的途径。系统一开始需花费两至三秒分析玩家的体型，因为我们比Tsunoda矮了几吋，萤幕上的人物身高开始调整。下述记载也许听来像是浮夸不实，小从抓抓鼻子大至前后跳跃的运动都能为Natal所追踪。象徵

令人联想到Dreamcast游戏Cosmic Smash的Ricochet，是一项简单的3D物理打砖块游戏，有效展示部份Natal系统的能力。我们起先遭遇的困难在于玩家与游戏的空间分野。感知游戏中球体于现实世界的定位并不容易，这使得玩家试图于现实空间中对虚拟球体作出回应成为挑战。此外当我们试图回击球体时，我们的动作在球体跑出玩家可及范围之外后，会有一刹那的延迟。

儘管我们对于Natal系统读取分析玩家运动的优秀精确度疑虑不再，从3D空间(现实)转化至2D平面(萤幕)的操控联想仍是一项问题。Ricochet是一款要求玩家以迅速动作操纵大量球体运动的游戏。

在技术demo Ricochet的展示后，预期Natal计划的未来将仅限于类似迷你游戏的体验会是愚蠢的，且该类型的应用无疑浪费了Natal系统所能提供的精确度。Ricochet究竟证明了什麽？至少我们可以回答Natal计划究竟是真是假 -- 答案只有一个： YES。

算上这个起码四家大媒体公开褒奖PN好用、实用，看样子八九不离十
