לא מפעיל סלולרי – רשת חברתית

Thursday, October 1st, 2009

רשתות חברתיות ,כפי שאנחנו מכירים אותן כיום, החלו להיות פופולריות בראשית המאה (אוי, זה נשמע ממש עתיק). אנחנו מתלהבים משירותים כגון פייסבוק, מיי-ספייס, לינקד-אין, טוויטר ואחרים בגלל יכולת השיתוף וזרימת המידע בינינו לבין הסובבים אותנו. אולם, נראה ששכחנו שלפני ביאת הפייסבוק ודומיו היו פה רשתות חברתיות, שקיימות עד היום. אני מדבר כמובן על הרשתות הסלולריות.mobile-social-networking

רשת סלולרית היא רשת חברתית. במקום קליינטים ודפדנים יש לנו מכשירי סלולר. התוכן הוא קול וטקסט (אני בכוונה מתעלם לרגע מה-DATA) ושם המשתמש הוא מספר הטלפון שלו. אבל כאן נעצר הדמיון ומתחיל ההבדל. יכולת השיתוף מוגבלת. לקוחות סלולר עושים את רוב השיחות והמסרונים שלהם אחד-על-אחד. גם יכולת הוספת חברים היא די מוגבלת. המשתמש מזין בצורה ידנית את מספר הטלפון של החבר שלו. אם אותו חבר ישנה את מספר הטלפון שלו, המשתמש לא ידע על על כך מייד (כמה פעמים התקשרנו למספר טלפון רק כדי לשמוע הודעה קולית שמודיעה על שינוי מספר?). אפשר למצוא עוד הרבה הקבלות שבהן תמיד תמצא הרשת הסלולרית בצד המוגבל, אבללרשת הסלולרית יש יתרון אחד מובהק – זמינות. לכל אחד מאיתנו יש מכשיר סלולרי אותו הוא נושא לכל מקום ובכל עת – ג ם כשאנחנו לא מול המחשב. אם כן, למה אנחנו לא רואים טלפונים ורשתות סלולר עם תכונות “חברתיות”?

הרבה דובר על כך. פחדנות וחוסר חזון הם המוטיבים החוזרים ברוב המקרים. אולם בשנים האחרונות התחלנו לראות ניצנים של שינוי. הבולט בהם הוא סדרת הטלפונים של INQ. הטלפון משלב אנשי קשר מרשתות חברתיות כגון פייסבוק, סקייפ וטוויטר ישירות לתוך ING_bigספר הכתובות של הטלפון. כלומר, לא עוד אפליקציות שצריך להזיע ע”מ להוריד ולהפעיל אותן אלא ממש ערוצי התקשרות נוספים כחלק אינטגרטיבי מהטלפון. שליחת הודעות מיידיות (Instant Messages) שקולה לשליחת SMS. שיחה לחבר בסקייפ גם כן אפשרית כמו שיחת טלפון רגילה. הטלפון כבר מופץ ע”י מספר מפעילים סלולרים בולטים בעולם כגון Singtel הסינגפורית ו-3 הבריטית.

יש עוד הרבה מקום לחדשנות גם אחרי INQ. למשל, סינכרון בין מספרי טלפון של מנויים ושמות משתמשים שלהם ברשתות חברתיות. שירות כזה יאפשר למנויים להוציא שיחת טלפון רגילה (לא VoIP על-גבי רשת הדאטה) לשם משתמש – אשר ניתן לזהות אותו בצורה קלה וידידותית והגישה אליו תמיד מעודכנת – ולא למספר חסר משמעות. גם המעפילים ישמחו. אין חשש לקניבליזציה בשיחות (השיחה היא שיחת GSM רגילה – זוכרים?) ולצד זאת יגבר השימוש בדאטה לטובת עדכון פרטים ושיתוף.

jajah_twitter_call

לפני כשבועיים השיקה JAJAH שירות שמדגים מה ניתן לעשות כאשר משלבים טלפוניה מסורתית עם חדשנות אינטרנטית . השירות מאפשר למשתמשי טוויטר לדבר זה עם זה ע”י הקלדת שם המשתמש הטוויטרי תוך כדי שמירה על פרטיות. רק משתמשים שעוקבים זה אחר זה יכולים לדבר בינם וגם כאשר הטלפון מצלצל לא מופיעים מספרי הטלפון. דוגמה לכך ניתן לראות בסרט הוידאו ב- CNN למטה:

עדכון (מחורים ברשת): שירות דומה מציעה חברת Mobivox, אשר מאפשרת ללקוחותיה להתקשר מהטלפון ליעדים בסקייפ.

מעסיקים מיוחדים בהייטק

Sunday, August 30th, 2009

logoישנם רגעים בחיים שהמילה ‘ציניות’ מתחלפת ב’ציונות’. קבוצת “מעסיקים מיוחדים בהייטק” הינה קבוצה ששמה לה למטרה לפתוח   לבבות ודלתות לאפשרויות העסקה של אנשים בעלי צרכים מיוחדים בעבודה בהייטק. אנשים בעלי צרכים מיוחדים הינם אנשים עם לקויות פיזיות או כאלו שעברו משבר נפשי אולם יש להם זיקה למחשבים והם מעוניינים ויכולים להשתלב בעבודה בהיי-טק.

השבוע העברתי הרצאה על רשתות חברתיות באינטרנט (להורדה לחצו כאן) בפני חלק מאותם אנשים מיוחדים. היוזמה להרצאה באה מרן שפי ודרור ולד מחברת ג’ג’ה (JAJAH) אשר מרכזים פעילויות דומות במסגרת פרוייטק מעורבות חברתית בג’ג’ה. פעילויות אלה כוללות הרצאות דומות אחרות שנוגעות להייטק וכן עבודה משותפת בין נפגעי נפש ומתנדבים מג’ג’ה בתחומים כגון שפות תכנות, בניית אתרים, Flash, שימוש באינטרנט ועוד. חשוב לציין שהפעילות ההתנדבותית קיבלה עידוד ותמיכה מצד עמיחי אורן, ה-CTO ומנהל הפיתוח של ג’ג’ה.

פעילויות התנדבותיות כגון אלו הינם חלק מפרוייקט מפגש בין אנשי מחשבים לנפגעי נפש אותו מרכזת סיגל גוטרזון. הפרוייקט “רץ” כבר מספר רב של שנים במהלכם זכה להכרה מטעם המחלקה לבריאות הנפש במשרד הבריאות, כפרוייקט תומך שיקום, וכן פעמיים ב”אות גלובס” לעסקים קטנים.

ההרצאה שהעברתי אפשרה לי להכיר יותר את הפעילות הנ”ל ואת האנשים המלווים אותה. אני שמח שהייתה לי הזדמנות להתודע לפעילות מבורכת זאת. אני מקווה ומאמין שפרוייקט “מפגש בין אנשי מחשבים לנפגעי נפש” וכן קבוצת “מעסיקים מיוחדים בהייטק” ודומיהם ימשיכו לקצור פירות בשילובם של פרטים חלשים בחברה הישראלית.

Yahoo Messenger 10 Beta is Released

Tuesday, August 25th, 2009

Yesterday Yahoo released Yahoo messenger 10 beta. Amongst the new and improved features are High-quality video calls (requires both sides to have the new version), new “Y! Updates” view of the contact list, improved localization support and more nice tweaks. I especially like the new Y! updates view. In addition to your contact’s status, the new view aggregates your contacts activities on Twitter, Picasa, YouTube, Last.fm and Yelp. I hope more social networks like Facebook and MySpace will be included in later versions.

One of the new tweaks is related to making voice calls. When you make a PC-2-PC call and the recipient does not pick up / declines / goes to Voicemail, Yahoo Messenger will offer to sign up to Yahoo Voice (supported by JAJAH) and reach the contact on his landline or mobile phone.

Google Voice – how to make outbound calls?

Tuesday, March 17th, 2009

I can’t believe I didn’t mention it in my last post. Google Voice is really great but it looks to me like it’s more focused on getting incoming calls than placing outbound calls (even though they’re free for now). A Google Voice user has 3 ways to make a call: making a callback from his on-line account, calling back people who left a voicemail or manually typing the desired number.

Let’s have a closer look. The first way is simple and intuitive. Google Voice on-line page is based on Google’s famous UI principles thus making it easy to make the call. However, it still requires going on-line with your computer which is somewhat limiting. I didn’t hear about a mobile web version for the service like JAJAH’s mobile web, but I’m sure Google is working on it right now. The second way to make calls  is to callback a person back from a voicemail but that’s more a by-product for the voicemail service than a “legitimate” way to place calls.

The third way is to call your Google Voice number, press 2 and then manually type the destination number . That’s a big problem. Most of the mobile calls we make are from the phone’s address book or call log. Typing the number requires memorizing the number and the entire process takes time. The solution is either to have a number mapped to the destination, like JAJAH Direct service, or install a mobile plug-in. A mobile plug-in can be installed on most phones today and use the phone’s capabilities. On smart phones devices like iPhone/iPod, Symbian, Windows Mobile and Android, Mobile VoIP calls can made thus saving you the cost of local call to your operator. In addition, the applications can intercept outgoing calls and route them through Google Voice. The advantage here is that the user doesn’t have to learn new tricks to make calls. She’ll still dial like she used to and the application will make the decision how to route the call. On features phone, which are still the majority of phones today, a J2ME plug-in can be installed to make calls. The plug-in could interface with the phone’s address book, allowing the user to choose a contact to dial to rather than typing the number manually. My guess is that Google will soon launch applications for mobile phones.

Google Voice – what’s next

Saturday, March 14th, 2009
Google’s latest revolution and the usual suspect

By now, the news of Google Voice has spread all over the web. Some celebrates the new revolution from the world’s web seminary, while other raise the usual concerns about invading your privacy. To the skeptics, I can only say, common! Nobody’s forcing you to use it. Google’s power is incredible but there’re still alternatives out there. Besides, free services in exchange for some level of privacy invasion already exist and gain popularity. (Gmail, being the most obvious example, but there’re others). Moreover, we already deliberately provide so much private information about ourselves in Facebook, Twitter, windows messenger status and others that privacy claims about big brother monitoring seems somewhat archaic.

One number, many friends

However, Google Voice is facing other challenges before it become globally  available and gain widespread use. First of all, Google Voices should help its users to spread their new number with their friends, family and colleagues. Perhaps a variation of Google Mobile sync service could help in that. Another related problem is that the numbers given to users are still only US. Even if the service becomes global, the given number is always local to the user. So, if I get a US number and my friend live in Austria, it will still cost a lot of money to make the international call from Austria to Germany. Of course, this is a common problem with all international calls. However, if Google has ambitions to make their service ubiquitous, they’d need to find a solution to this issue. JAJAH Direct can provide such a solution and at low-cost rates.

I’m sorry, what did you say?

One of Google Voice prominent service is it’s voicemail transcripts. It’s a great service, if, Google can indeed make fully automated transcriptions. Personally, I don’t see that happening in the near future. Google’s Speech-to-text services are gaudi and GOOG-411. Both services are limited to recognizing specific words out of a pre-defines list like Joe’s Pizza, economics, Texas. At this point, it’s not possible to fully transcribe complete voice mails without making mistakes, asking the user to repeat some words or have human intervention. A partial solution might be to make an educated guess about the nature of the voicemail content. If Google could assume a particular voicemail is of specifi context (entertainment, sports, business), it could reduce the number of transcription mistakes to a minimum. Since Google already has vast knowledge about its users habits and interest areas, that seems to be taken care of. Also, let’s not forget that transcription service should be able to understand different accents, languages, oral mistakes made by the user’s themselves,  nick names, voice interference and more before it become accurate. I know of only one such device that does a similar task, but, it will be in production state only 142 years form now.

One last thing

In addition to the above , Google has to overcome huge operational and regulatory challenges. Call termination, VoIP-related fraud, IP call routing and hosting are just few of issues any valuable VoIP company has to deal with. I wonder how much Google Voice is ready to cope with these issues, especially if it wishes to become a global service provider like JAJAH.
