國外新的大尺寸多點觸控技術

2008年9月30日 2 則評論
以前曾經異想天開的說為何不用一整排的CCD來做運算, 就可以解決 Ghost Point 問題,

結果想不到義大利佬真的把它給實做出來, 而且用的是成本低廉的 25fps 非廣角的

Webcam, 主要的軟體難度在於他們提出解決了攝影機同步的問題, 不過我個人認為

25fps 的速度實在太慢了, 如果能用交錯取樣的方式, 也許可以增加到 50fps,100fps

在低成本的製作下, 還需要解決外在光源影像, 取樣背景變化影響, 仔細觀察其下方

似乎有擺上一個黑色的棒子來幫助分離手指影像.

不過根據我個人的想法應該是WebCam用紅外線的, 同時具有紅外線發光源,

然後採用交錯的方式進行取樣以提升反應速度, 然後將其包裝成如同 UbiqWindow

一般的一支棒子, 我相信對量產化及市場反應會有較好的幫助.

希望有同好一起來研究呢~呵呵

舊瓶新裝 – 滑動輸入法是新概念? 老觀念?

2008年9月15日 尚無評論
下面這網頁你看的到嘛?
在觸控上很不錯的概念輸入法. 
 


呵呵, 這種輸入方式我在 n 年前那時候還是 8088 單色時代就用過
 
只是那時候用滑鼠還挺難控制的, 不過用來做數字輸入挺方便的
 
類似像是電話轉盤一樣, 不過是用滑動方式輸入, 一但進入中心區域
 
就會產生軌跡的明顯斷點, 然後根據移動向量變化作為特徵比對,
 
字太多的話, 很容易判別. 這樣的概念跟現在 firefox 有一種手勢輸入法很像,
 
在一個圈圈內,  然後判斷出去圈圈的向量換成一組序列來定義手勢
 
類似下面的圖的蓋念, 不過我那時後只有做數字, 因為太多的話向量
 
差異不大, 尤其解析度不高的時候, 最好先透過二元樹展開, 把常連貫的字母
 
分開擺在不一樣的地方, 這樣應該就會像寫字一樣順喔. 還沒實做過. 呵呵
 
 
這是示範 APPLE, 其中 PP 要進入中間點再出來, 對右手手勢來說一搬都會從偏右在近來
 
把圓型向量切 32 階的話, 每階是 11.25 度, 這樣的取樣度比較不太容易, 除非內徑的圓更小
 
這改良方式一式把內徑圓縮小, 取得進出向量的更大差異化, 另外一種就是比較難的分析,
 
把圓型切成 16 階, 甚至 8 階就好, 每個有 22.5 或 45 度, 透過其進出的軌跡角度來判別
 
如下圖所示
 
 
 
Palm Pilot 用的辨識方法就有點類似這樣的概念, 主要都是用座標系絕對向量, 而非位移相對向量,
 
Palm 把整個比畫軌跡轉成只有八個方向, 例如 A 就轉換成 ^ 就是 2->2->2->2->4->4->4->4 轉成特徵就是 2->4
 
L 就是 5->5->5->5->5->3->3->3 轉成特徵就是 5->3, 所以 Palm 的辨識速度很快, 但是辨識率要高, 就必須避開
 
特徵重複的字母寫法, 所以 Palm 才會有自己專利的字母手勢寫法..
 
這都是很久以前玩的~呵呵~很久沒用到, 想不到現在還會出現在觸控上面, 真是奇蹟呢.
 
我個人也是覺得, 用鍵盤來做滑動, 第一沒有實體鍵盤, 滑動停止的轉折點很難抓, 很容易滑過頭,
 
第二就像您說的在大的觸控屏會滑到手破皮吧~呵呵~所以用一個小圓盤來代替比較好啦~~

UI 設計新概念 – 翔基的網頁即將改版

2008年9月12日 尚無評論
翔基的網頁將在今年內改版, 預計未來的 UI 操作模式將會呈現全新的風貌如何稱為全新的風貌呢? 就是充分發會 RIA 的 Rich Interactive Application呵呵, 這是我在微軟 MIX’08 上面聽到對 RIA 的新定義, 也就是將來翔基

會有一個全互動架構的網頁, 同時將會以創新的 UI 呈現方式來呈現網頁內容,

以後操作網頁就會像是操作手機, HTC Diamond 或是 Apple iPod 的介面一樣,

下面就是一些基本的介面構想, 我們將會在年底就能完全呈現出來.

 

當然這兩種模式只是把目前網頁上常用的選單做一些小小的改變, 就可以給使用者帶來全新的感受, 這樣的改變, 未來能將會充分運用在網頁中, 會有各種不同新型態的呈現方式, 敬請各位好友期待囉~~
 網頁持續改版中~~~~敬請期待~~~呵呵

Gesture-based digital signage: A new marketing future

by Michael Mascioni*

• 08 Sep 2008When people talk about gesture-based digital signage, the conversations are usually geared toward the future. But research is showing that the future apparently isn’t far off, based on the growth and impact of gestural displays in shopping malls and other public places. 
In fact, Mike Ribero, CEO of Reactrix Systems, predicts an “explosion of gesture-based media in the next five years.” He adds that such media will “appear in places you’d never expect to see them.” 

 

From his perspective, gesture-based signs have significant advantages over traditional out-of-home displays: they’re “not intrusive, and capture the consumer’s attention without diminishing their control over interactive experiences.” One of the keys to gesture-based media is that they “hold the audience’s attention for a longer time,” and “attract people from a distance.” 

 

For example, a study conducted by Arbitron last November with 4,000 consumers in 20 malls exposed to Reactrix displays showed that consumers at those malls spent significantly longer amount of time in front of the gesture-based sign. 

In addition, 70 percent of consumers in that survey “actually interacted” with those displays,” he said. Ribero also believes the social networking experiences afforded by those displays are “far more enjoyable and robust experiences than those offered by traditional kiosks.”

Reactrix technology explained:

 
Reactrix’s gestural displays have been well received on a number of levels. According to Ribero, research conducted by shopping malls employing Reactrix displays have ranked those displays as “one of the most effective types of media” at their malls, and its displays are the “one of the highest revenue generating displays” in General Growth Properties’ shopping malls,” based on a study conducted by the mall in the first quarter of 2008. 

Reactrix generated such a strong response from the application of its gestural system with a STEPscape display for Samsung this year that even Reactrix “was flabbergasted.” The company had a single STEPscape display operating on a rotating basis in four shopping malls in Florida, where 20-25 back-lit displays were already installed.  

A study conducted by an outside research firm in Feb. 2008 with nearly 400 consumers found that 35 percent of consumers at those malls recalled the Reactrix display, while only 15 percent could recall the 20-25 static signs at the four locations. 

Reactrix recently applied its system in a unique way to the Florida lottery. The company used its SMARTspot technology to beam real-time Lottery jackpot numbers every Wednesday and Saturday to participating shopping malls in Florida. Through Reactrix’ STEPscape SMARTspot platform in mall walkways, users had a chance to participate in a lottery game by stepping on virtual Lotto balls floating above a yellow backdrop, triggering the appearance of virtual money where they step. They could also push the balls around and make them collide with each other.

Portugal’s gesture-based innovator

YDreams, based in Portugal, had considerable success with the YSenses point-of-sale promotion it developed for Compal at the “World of Flavors” fair at seven Continente supermarkets last year. The campaign was deployed throughout Portugal, according to Marta Vieira, director of business development and operations for YDreams. 

For that promotion, a game was presented on a large plasma screen displaying a fruit orchard populated by trees filled with fruit, allowing users to play and win prizes by purchasing four or more Compal products. Users had an opportunity to “pick” pieces of fruit from the orchard on the screen by clapping in front of the screen in an effort to pick as many pieces of fruit as possible from the Compal YSenses Interactive orchard.

The promotion generated “an average of 400 interactions per day,” and “customers who played the Compal Senses game were 40.3 percent more likely to actually purchase the brand’s products,” according to YDreams.

YDreams also developed an interactive cinema campaign called Happiness Factory for Coke. The campaign centered around a game which was designed to enable users to interact more with the Coke brand and allowed users to control the main character’s movements by waving their arms from left to right. 

In the game, the worker character runs left and right to in an effort to catch as many Coke bottles as possible falling from the sky. An announcer preps the audience for the surprise and mimics the worker during the game.

Research conducted with participants indicated the campaign’s major brand impact: 300 of those surveyed about the experience said they were “positively surprised by its innovative action,” and 40 percent of the respondents indicated increased brand awareness of Coke as compared to traditional in-cinema advertising.

YDreams elicited highly positive results with an interactive adver-game it delivered in +Cinema theaters in the Lisbon, Portugal, area to promote Vodafone’s Duplex ADSL brand this April. The game, which was developed together with the agency Brandia Central, allowed users to control the movements of the main character (VodaRed Man) on the screen by waving their arms in the air. That character ducks left or right to avoid hazardous objects that are hurled at him, and retrieve as many ADSL packages as possible.

According to surveys conducted with moviegoers participating in the game, “moviegoers who played the Vodafone game were more inclined to purchase Vodafone products,” reports YDreams. The surveys also found that brand recall and awareness of those products was higher than that generated by traditional cinema advertising.

YDreams also created a special buzz with an interactive product promotion it developed for Dove’s soap products at Sao Paulo movie theaters in 2007, which afforded moviegoers the opportunity to play with soap bubbles that appeared to descend on screens in those theaters. Webcams were installed at the back of those theaters to track the movements of those people while they were interacting with the bubbles. The moviegoers had an opportunity to push and burst bubbles on the screen through their gestures.

Gesturetek in malls

GestureTek is another company that has made a strong impact with its gestural interactive marketing displays in public places. The company had “great success” with a system it installed in the flagship store of Hudson Bay in Toronto with “multisports windows,” said Vincent John Vincent, president of GestureTek. The system, which was situated at the corner of a window in that store, utilized eight- by 12-foot projectors and featured special effects and ads for Hudson Bay. 

 
GestureTek has witnessed growing demand for its systems in retail digital signage applications over the past few years, as shopping  malls and other retail outlets seek new ways of making shopping a “destination experience” and more enjoyable. The majority of malls installing GestureTek’s systems are now using it for digital signage applications, Vincent said.

Most of the GestureTek experiences in shopping malls and retail outlets are entertainment, though they are ultimately designed to promote the brands of the malls and retail outlets and carry the logos of those operators. 

GestureTek’s ScreenFX system was an integral part of the launch of the Charlestown Mall in Ireland. The GestureFX family of interactive display systems can project visual content onto any surface, including floors, walls, tables, countertops and bartops. Users control multimedia content and special effects by moving their hands and bodies without the need for other user interfaces. GestureFX utilizes GestureTek’s patented video gesture control software and special camera technology.  

The system, which was installed in a high-traffic location inside the Charlestown Mall, was integrated into a Panasonic 103-inch plasma display, allowing users to interact with it. GestureTek’s GroundFX interactive floor displays were also installed at several entrances in the mall.

General feedback so far indicates that users have found that application an “enjoyable experience,” Vincent said.

GestureTek’s ScreenXtreme system was also used in a gestural brand experience for the Spanish retailer Musgo-SXT. In that window promotion, users were immersed in a soccer game through a multimedia interactive experience.

In addition, Target Stores has used GestureTek’s system in interactive billboards in an underground mall in Canada to great advantage. That system has proven to have a “positive effect on store traffic,” Vincent said.

Some retail applications of GestureTek’s systems are designed to promote specific products of particular companies. For example, Telefonica, a leading Spanish telecommunications company and part investor in GestureTek, is using GestureTek’s multitouch system to provide more information about its products and brand in its stores.  This application, framed around the Telefonica Retail Window, affords users an opportunity to collaborate with others while interacting with content on the screen.

The impact of gesture-based displays in public places will be even greater in the near future due to key new technological developments. One of the most important of those will be a greater convergence between gestural and mobile systems in public places, opening up even more expansive forms of interactivity in those settings, Vincent predicts.
