Development of the Nintendo DSi started at the end of 2006, around the time of the Wii's release. It was the first time Masato Kuwahara of Nintendo's Development Engineering Department served as a hardware project leader. Work went at a quick pace to meet deadlines; his team had to devise a theme for the new DS in time for a late December presentation, and by February 2007, most specifications for a chipset had to be completed. Kuwahara reported that his team had difficulty determining the potential market for the handheld during the design process; he said of their goal, "We have to be able to sell the console on its own . It also has to be able to meld into the already-existing DS market." The console's digital cameras were considered early in development: Nintendo president and Chief Executive Officer Satoru Iwata described the touchscreen as the Nintendo DS's sense of touch, and the microphone as its "ears"; a co-worker suggested that it should have "eyes". Kuwahara's team originally wanted one camera with a swivel mechanism, but this was abandoned due to concerns of reliability, cost, and the need of a thicker console. Owing to consumer demand, Nintendo also improved the handhelds' volume and audio quality and made it slimmer with larger screens compared to the Nintendo DS Lite. However, to improve portability without sacrificing durability, the GBA cartridge slot present on earlier models was removed. To compensate, Nintendo continued to support the DS Lite as long as there was consumer demand for it.
"I made the presentation then at the end asked everyone if this was a game system they would want to own. The result was three to seven. Three people wanted it, seven didn't. And I imagine that since one of the designers was standing right there in front of them, some of them held back their true opinion. In truth, it was probably more like one to nine. It was as bad as I had feared."— Kuwahara on Nintendo EAD's reaction to the original DSi designs.
The DSi's size was changed midway through development thus delaying its release. Its original design included two DS game card slots, because of demand from both fan communities and Nintendo employees, which consequently made it larger. When the console's designs were unveiled to Nintendo Entertainment Analysis and Development producers in October 2007, it was met with lukewarm reception due to its size. However, Iwata and Kuwahara's own hopes resulted in the creation of a prototype. A quick hands-on investigation led them to abandon the dual-slot design, which made the DSi approximately 0.12 inches (3 mm) slimmer. Ever since the handheld's in-company unveiling, its internal designs were finished along with assembly and durability specifications. Iwata described having to resize the console so close to manufacturing as being essentially the same as making another handheld.
Yui Ehara, designer of the DS Lite and DSi's original casing, had to redesign the latter. He advocated to change the six speaker apertures, as their circular perforations were redundant to the rest of the handheld's interface. He believed that this alteration also signaled a clearer distinction between the DSi and its predecessors while keeping the unit "neat" and "simple". Ehara hoped the DSi's added features would not interfere with his desired iconic image of the Nintendo DS product line: two rectangles, one on top of the other, with each half containing another rectangle inside. This model was publicly revealed at the October 2008 Nintendo Conference in Tokyo, along with its Japanese price and release date. While the DS product line's worldwide yearly sales figures had consistently surpassed those of its primary market rival, Sony's PlayStation Portable, demand for it in Japan was decreasing; Nintendo's launch of the DSi was intended to stimulate sales. The company was less concerned with releasing the DSi in other territories, where DS Lite market demand remained high.
Development of a large DS Lite model in 2007 eventually led to the DSi XL (known in Japan as the Nintendo DSi LL (ニンテンドーDSi LL, Nintendō DSi LL?). Nintendo had designed a large DS Lite model with 3.8-inch (97 mm) screens, compared to the standard 3-inch (76 mm) screens; development of this new handheld advanced far enough that it could have begun mass production. However, Iwata placed the project on hold due to consumer demand for the DS Lite and Wii. He later pitched the idea of simultaneously releasing large and small versions of the DSi instead, but Nintendo's hardware team was incapable of developing two models concurrently. After finishing work on the DSi, Kuwahara started the DSi XL project and became project leader. The DSi XL, a DSi model with 4.2-inch (110 mm) screens, was announced on October 29, 2009. Various names for it were considered, including "DSi Comfort", "DSi Executive", "DSi Premium", "DSi Living", and "DSi Deka" (Japanese for "large"). Mario creator Shigeru Miyamoto insisted on "DSi Deka". The handheld has an improved viewing angle over its predecessor, which allows onlookers to see the screen's contents more easily. This feature was absent from the large DS Lite model due to cost issues at the time, which also limited LCD screen size. The cost of LCD screens is determined by how many pieces are cut from a single large glass sheet. To keep these costs within a certain threshold, Nintendo set a screen size limit of approximately 3.8 inches (97 mm), which was later increased to 4.2 inches (110 mm).

Famous quotes containing the word development:
“Every new development for the last three centuries has brought men closer to a state of affairs in which absolutely nothing would be recognized in the whole world as possessing a claim to obedience except the authority of the State. The majority of people in Europe obey nothing else.”
—Simone Weil (19091943)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (18171862)
“Information about child development enhances parents capacity to respond appropriately to their children. Informed parents are better equipped to problem-solve, more confident of their decisions, and more likely to respond sensitively to their childrens developmental needs.”
—L. P. Wandersman (20th century)
