TIMING METRICS

1. Launch Time After Pitch Release measures the amount of time in seconds between pitch release and the start of the swing. The event of swing launch is illustrated using a white sphere on the pitched ball path in the virtual realm so that the user can obtain a more physical understanding between the timing of the swing launch in relation to the speed of the pitch.

2. Launch Time Before Home Plate Crossing measures the amount of time in seconds between the start of the swing and when the pitch crosses the front of home plate.

3. Time to Contact measures the amount time in seconds between the start of the swing and when bat-barrel contact occurs or when the nearest distance between the ball and barrel occurs. The event of ball-barrel contact or minimum distance between the ball and barrel during the swing is illustrated using a black sphere on the pitched ball path and a black cylinder on the barrel swing path in the virtual realm so that the user can obtain a physical understanding of where contact or the nearest point to contact has occurred.

4. Bat vs. Ball Arrival Time measures the relative arrival time of the ball and bat across home plate in seconds. A positive time value means that the bat arrived at home plate first so if contact is made then contact occurs around the front of home plate and the pitch is pulled. Whereas a negative time value means that the ball arrived at home plate first so if contact occurs then contact occurs around the tip of home plate and the pitch is hit to the opposite field. If this time is zero and contact occurs, then contact occurs over the middle of the plate and the ball is hit up the middle

BAT SWING AND PITCHED BALL METRICS

1. Attack Angle in degrees measures the angle between swing plane of the bat relative to the ground as the bat crosses home plate from back to front. High average hitters have Attack Angles equal to and opposite (negative) of the pitch’s Descent Angle.

2. Vertical Angle in degrees measures the angle between the swing plane of the bat relative to a horizontal plane over home plate in a direction moving laterally from one side of home plate to the other. High average hitters also have Vertical Angles equal to the pitch’s Lateral Angle.

3. Connection Angle in degrees measures the angle between the bat and the player’s torso (tilt of player’s torso determined from HMD orientation) and is measured as the bat crosses over home plate. Hitters with Connection Angles of 90 degrees optimally utilize their body movement in powering the swing.

4. Descent Angle in degrees measures the angle between the trajectory plane of the pitched ball relative to a horizontal plane over home plate as the ball crosses home plate from front to back

5. Lateral Angle in degrees measures the angle between the trajectory plane of the pitched ball relative to a horizontal plane over home plate as the ball crosses home plate from one side to the other side.

BAT SWING KINEMATICS

Experts in the field of Kinesiology, the scientific study of human body movement, will not only find the maximum magnitudes of the velocities and accelerations useful in analyzing and optimizing the swing mechanics of a hitter, but also the relative timing of these maximum magnitude events will provide useful information in evaluating the sequence of movement within the hitter’s swing.

1.The Max Sweet-Spot Speed of the Bat Barrel is measured in MPH during the swing along with the timing of this event in seconds WRT swing launch. The position and orientation of the bat barrel for this event is shown in the swing path of the bat barrel as a white cylinder in the virtual realm.

2. Max Hand Speed is measured in MPH during the swing along with the timing of this event in seconds WRT swing launch. The “hand position” on the bat for this event is shown in the swing path of the bat as a white sphere in the virtual realm. The hand position is denoted as the point on the bat handle that is six inches above the bat knob. Consequently, this is essentially the pivot point on the bat handle between the hitter’s two hands.

3. Max Bat Knob Speed is measured in MPH during the swing along with the timing of this event in seconds WRT swing launch. The position of the bat knob for this event is shown in the swing path of the bat knob as a white cube in the virtual realm.

4. Max Bat Rotational Speed is measured in RPS (revolutions per second) during the swing along with the timing of this event in seconds WRT swing launch. A long white rod in the virtual realm is used to illustrate in the bat swing path where this event occurs.

5. Max Bat Knob Acceleration is measured in g’s (1 g = 9.81 m/s2) during the swing along with the timing of this event in seconds WRT swing launch. The position of the bat knob for this event is shown in the swing path of the bat knob as a black cube in the virtual realm.

6. Max Bat Rotational Acceleration is measured in RPS2 (revolutions per second squared) during the swing along with the timing of this event in seconds WRT swing launch. A long black rod in the virtual realm is used to illustrate in the bat swing path where this event occurs.

HIT BALL FLIGHT METRICS (if ball-barrel contact occurs)

1. The Exit Velocity of the hit ball at contact is measured in MPH. Exit Velocities greater that 95 MPH with Launch Angles between 25 and 30 degrees tend to enhance the likelihood that a home run will occur.

2. The Launch Angle is measured in degrees and is the angle between the direction of the hit ball’s trajectory off the bat and the ground. Launch Angles between 25 and 30 degrees with Exit Velocities greater than 95 degrees tend to enhance the likelihood that a home run will occur.

3. The Direction Angle is measured in degrees and is the angle that provides the direction of the hit ball relative to “up the middle” or the center of the baseball diamond. For example, the Direction Angle is 0 degrees for a ball hit directly toward second base, the Direction Angle is 45 degrees for a ball hit down the first base line, the Direction Angle is -45 degrees for a ball hit down the third base line, and the Direction Angle is -180 or 180 degrees for a foul ball hit straight back. Direction Angles with magnitudes between 45 and 180 degrees denote foul balls.

4. Flight Distance is measured in feet and denotes the total distanced that the hit baseball has traveled before hitting the ground.

5. Hang Time is measured in seconds and denotes the total time that the hit baseball has traveled in the air before hitting the ground.

6. Hit Probability is measured as a percentage (%) and provides the degree of likelihood that the outcome of the hit ball is a hit. Players who hit for high average would want to achieve percent values as large as possible (max is 100%).

7. Home Run Probability is measured as a percentage (%) and provides the degree of likelihood that the outcome of the hit ball is a home run. Players who are power hitters would want to achieve percent values as large as possible (max is 100%).

Solutions: Getting From Opportunity to Vision

Solutions: Getting From Opportunity to Vision

by Edmond DoughertyNo Comments

In this entry we’ll discuss SOLUTIONS. We recently talked about OPPORTUNITY IDENTIFICATION and then VISION as important steps in the
product development journey. Journey? Hmmm. It’s actually a pretty good analogy, so let’s ride it. In terms of a journey, OPPORTUNITY IDENTIFICATION is the beginning and VISION is the end.

Normally you’ll start a journey at point A, and hope to arrive safely at point B. In developing a product, you start by identifying the opportunity, that’s point A. Point A is a dark, flawed place where pain and problems exist. Point B is our vision: a better world, the problem is fixed, the sun is shining, the pain is relieved and life is made better by your idea in some way.rubik-cube

But how do we get from point A to point B? That’s where the SOLUTIONS come in. Solutions provide us a path to move from A to B. Here’s a simple example. Suppose we have strong evidence that basketball players have trouble keeping track of the time left on the shot clock. Not the most important problem in the world admittedly, but a problem/opportunity nonetheless. High level basketball moves so fast the players don’t have the ability to keep track of time, even with digital shot clocks displayed all over the stadium. So this is our world at point A – players are not well aware of the shot clock. The vision for point B then should be pretty obvious…imagine a world where players know how much time is left. All we need is a solution, our road from point A to point B.

In a journey, there are many ways to get from point A to point B, and a good traveler will get out the maps (Google or otherwise), train and plane timetables, in order to consider many paths and options. Designers should do the same when considering solutions to achieve their vision. The cats at Novation believe the best way to develop solutions is to start with a brainstorming session. A simple 15 minute session can generate hundreds of ideas – some of them good.

“Some of them!” you exclaim?

Yes, that’s right….not all of the ideas are good ones. A lot of the ideas generated in brainstorming are pretty useless, but all you need is a single good solution. If you have scores of ideas to sort through it is very likely you’ll come up with the one that works to get you to your vision quickly.

In the next few blog entries, we will explain how we brainstorm so you can develop multiple solutions, and more importantly, we will discuss how to evaluate those solutions so you can find the right one for you.
Is there more than one solution to most problems?

Vision: Defining and Refining Product Ideas

Vision: Defining and Refining Product Ideas

by Edmond DoughertyNo Comments

visionOnce we’ve found a potential business opportunity, an idea we think may have a market, the next thing we need is a vision. As engineers and designers, our instinct is to go right to a solution and prototype, and skip the vision. But here at Novation Tech, we take the time to do it right and look into the future to define our vision.

That’s right, we’re time travelers. Well, not exactly time travelers, but we try to envision how our idea might come to life in the future. We try to imagine in great detail, the final product. The look. The feel. As they say in design school – the form, fit and function.

We try to imagine how our customers might use our product, what functions it must perform, and how well it must perform its functions. We don’t worry about how we can make it happen yet; for the time being we assume we build it to do anything we need.

One valuable exercise is to design a one page advertisement for your future product. A sketch, a description of the product, a list of its capabilities, some specifications, and anything else you might look for if you were going to buy the product. It is a great way to define your vision.

Since you now have an idea and a vision, in the next entry we’ll discuss how you get from idea to vision.

Ideas: The First Steps on the Road to a Final Product

Ideas: The First Steps on the Road to a Final Product

by Edmond DoughertyNo Comments

ideaSeveral readers have asked how we get our ideas for products. We have several creative minds working on our team, each with their own interests and views. If left on their own, the ideas and projects would wander wildly. They would be fun and interesting – two of our goals – but we are a business and need to ensure that our research and development resources are spent wisely. So how do we herd this bunch of cats?

In this and the next couple of blog entries we will take you through the process, from idea to innovation.

The first thing we do when we want a new product is to look for pain. Ouch… that doesn’t sound good does it? But as creative designers who are also entrepreneurs, we don’t want to develop a solution looking for a problem. We want to find a real life problem (pain) first and then find a solution. Finding what makes people unhappy, frustrated, dissatisfied, finding their pet peeves, is a great place to start in developing a new product. Think about it…what really bugs you about your day to day life? Dislike your alarm clock? Hate making breakfast/your boring commute/your uncomfortable desk? Hmmm. How many people are there who feel the way you do? Probably a lot. Chances are by finding the pain, you may have uncovered an opportunity for a profit making product or two.

So begin a collection of all those observations of what annoys people, how you can make a situation better, and we’ll show you how to take those ideas to reality.

In the next entry we’ll talk about Vision.
