─ Tell us about the ideas and concept behind the creation of the LSPX-P1 portable ultra-short throw projector.
Murasawa: The Life Space UX concept, which includes this portable ultra-short throw projector, focuses on how our living spaces can be transformed.
─ What is the recommended way to use the LSPX-P1?
Murasawa: The LSPX-P1 is connected to an external input device to enjoy TV, movies and games, just like a regular projector. It also uses an ultra-short throw lens, so it doesn’t need the projection distance usually required for conventional projectors, enabling it to be used in a variety of locations.
─ Was there anything that left a particular impression on you during the development process?
Murasawa: One of the features of the Life Space UX concept is that we focus not solely on the product itself, but also on how the product will fit into the environment in which it is placed. When planning the product itself, we consider these factors across a wide range of details.
For example, conventional projectors have on their main body a power button and several other buttons for focus, volume and various settings. While we obviously focused on the device’s user-friendliness for our customers, we decided to place only the power button on the body of the LSPX-P1. As for the ultra-short throw, we assumed that customers would naturally put the projector at some distance from themselves, so we decided to put together all the various operational buttons on a smartphone application, and then create an autofocus setting to enable the focus to adjust automatically if the projector is moved. We believe that we have achieved a product that combines user-friendliness with all the concepts we had hoped to convey.
─ The compact projector body is equipped with everything, including the battery and speakers. What did you struggle with achieving the ideal size?
Murasawa: We really struggled with making the projector a compact size that would be portable. The portable ultra-short throw projector is approximately 8 cm wide, which is the size that we determined could be gripped easily in one hand.
The target width of a compact 8 cm was incredibly difficult to achieve. Although compact and bright, the laser light source generates a lot of heat. Furthermore, in order to maintain the harmony between the displayed video content and the room, we concealed components such as heat vents and video terminals, which are reminiscent of AV devices and electronic products, by wrapping them in perforated metal. This process reduces heat waste efficiency while suppressing operational noise to levels of 22dB or less, which is roughly equivalent to the sound of rustling foliage.
