Sensation and Perception3:42 with Hope Armstrong
How are digital products sensed and perceived? Let's take a closer look.
- Sensation: the immediate, relatively unprocessed result of stimulation of sensory receptors, such as touch, smell, taste, hearing, and vision
- Perception: how sensory information is organized, interpreted, and consciously experienced
- Proprioception: an awareness of the position and movement of the body
Let's take a closer look at how products are sensed and perceived. 0:00 When designing digital products, the first sense that comes to mind is likely vision. 0:05 While vision certainly shapes the user experience for 0:11 sighted folks, there are other sensations at play as well. 0:13 Sensation refers to the immediate, 0:18 relatively unprocessed result of stimulation of sensory receptors. 0:20 Information is taken in via touch, smell, taste, hearing, and vision. 0:25 Touch is a common sensation with digital products. 0:32 Haptic feedback is the use of touch to communicate with users. 0:35 Think of a time when you set an alarm on your phone to vibrate. 0:40 That vibration is haptic feedback. 0:44 It's also common in gaming and virtual reality as it expands a 2D 0:46 experience on a device into a more fully embodied experience in the real world. 0:52 Hearing is another sensation that is affected by digital products. 0:59 When your phone gets a call, it plays a ringtone, and 1:04 many apps offer the option of playing a sound when a notification is received. 1:07 As for smell and taste, 1:13 those senses aren't involved in the digital product experience, yet. 1:15 Maybe that's for the best. 1:19 If the Internet started pumping out weird smells as I browse the web, 1:22 I don't think I'd be a fan. 1:26 But outside of digital product design, smell and taste can certainly be applied 1:28 to other forms of interactive design, such as experience design and service design. 1:33 These disciplines craft experiences in the physical world, and 1:39 go beyond devices like computers and mobile phones. 1:43 Next up, let's take a look at perception. 1:47 Perception is how sensory information is organized, interpreted, and 1:51 consciously experienced. 1:55 It's a person's unique mix of past experiences, learnings, and expectations. 1:58 Since it's continuously being reshaped and 2:03 molded, it can be changed and influenced over time. 2:07 An example of this is pattern recognition. 2:11 Our brains are constantly filtering out information and 2:15 stimuli of various importance. 2:18 Thus, the designer's pursuit of shifting the user's attention towards what matters. 2:20 User researchers employ studies that use eye tracking software 2:27 that analyzes a user's eyes as they move across the screen. 2:31 These studies have shown that people have developed banner blindness. 2:35 Our brains have been exposed to so much banner advertising 2:40 that anything that resembles the common shape and placement of banners is ignored. 2:44 So take care to avoid presenting important information like a banner ad, 2:49 because that's likely to get overlooked. 2:53 Perception also extends to the physical body. 2:56 Proprioception is an awareness of the position and movement of the body. 2:59 Mobile devices and gaming systems are equipped with accelerometers and 3:05 spatial sensors. 3:09 These detect motion and gestures, and 3:11 these interactions can be a valuable input to shape the user experience. 3:14 Fitness apps such as Fitbit use the accelerometer to detect movement and 3:19 count user's steps. 3:23 That's it for sensation and perception. 3:25 Hopefully, these lessons have given you a more nuanced view of how 3:29 people interact with technology. 3:32 Now that we have these interaction design fundamentals down, 3:35 join me as I design interactions in the next stage. 3:38
